In his book “How to Solve It,” George Pólya (1945) said, “One of the most important tasks of the teacher is to help his students. This task is not quite easy; it demands time, practice, devotion, and sound principles. The student should acquire as much experience of independent work as possible. But if he is left alone with his problem without any help, he may make no progress at all. If the teacher helps too much, nothing is left to the student. The teacher should help, but not too much and not too little, so that the student shall have a reasonable share of the work.” (page 1)
What is a problem in mathematics? A problem is “any task or activity for which the students have no prescribed or memorized rules or methods, nor is there a perception by students that there is a specific ‘correct’ solution method” (Hiebert, et. al., 1997). Problem solving in mathematics is one of the most important topics to teach; learning to problem solve helps students develop a sense of solving real-life problems and apply mathematics to real world situations. It is also used for a deeper understanding of mathematical concepts. Learning “math facts” is not enough; students must also learn how to use these facts to develop their thinking skills.
According to NCTM (2010), the term “problem solving” refers to mathematical tasks that have the potential to provide intellectual challenges for enhancing students’ mathematical understanding and development. When you first hear “problem solving,” what do you think about? Story problems or word problems? Story problems may be limited to and not “problematic” enough. For example, you may ask students to find the area of a rectangle, given the length and width. This type of problem is an exercise in computation and can be completed mindlessly without understanding the concept of area. Worthwhile problems includes problems that are truly problematic and have the potential to provide contexts for students’ mathematical development.
There are three ways to solve problems: teaching for problem solving, teaching about problem solving, and teaching through problem solving.
Teaching for problem solving begins with learning a skill. For example, students are learning how to multiply a two-digit number by a one-digit number, and the story problems you select are multiplication problems. Be sure when you are teaching for problem solving, you select or develop tasks that can promote the development of mathematical understanding.
Teaching about problem solving begins with suggested strategies to solve a problem. For example, “draw a picture,” “make a table,” etc. You may see posters in teachers’ classrooms of the “Problem Solving Method” such as: 1) Read the problem, 2) Devise a plan, 3) Solve the problem, and 4) Check your work. There is little or no evidence that students’ problem-solving abilities are improved when teaching about problem solving. Students will see a word problem as a separate endeavor and focus on the steps to follow rather than the mathematics. In addition, students will tend to use trial and error instead of focusing on sense making.
Teaching through problem solving focuses students’ attention on ideas and sense making and develops mathematical practices. Teaching through problem solving also develops a student’s confidence and builds on their strengths. It allows for collaboration among students and engages students in their own learning.
Consider the following worthwhile-problem criteria developed by Lappan and Phillips (1998):
Of course, not every problem will include all of the above. Sometimes, you will choose a problem because your students need an opportunity to practice a certain skill.
Key features of a good mathematics problem includes:
Problem solving is not a neat and orderly process. Think about needlework. On the front side, it is neat and perfect and pretty.
But look at the b ack.
It is messy and full of knots and loops. Problem solving in mathematics is also like this and we need to help our students be “messy” with problem solving; they need to go through those knots and loops and learn how to solve problems with the teacher’s guidance.
When you teach through problem solving , your students are focused on ideas and sense-making and they develop confidence in mathematics!
Selecting activities and/or tasks is the most significant decision teachers make that will affect students’ learning. Consider the following questions:
By definition, a “ low floor/high ceiling task ” is a mathematical activity where everyone in the group can begin and then work on at their own level of engagement. Low Floor High Ceiling Tasks are activities that everyone can begin and work on based on their own level, and have many possibilities for students to do more challenging mathematics. One gauge of knowing whether an activity is a Low Floor High Ceiling Task is when the work on the problems becomes more important than the answer itself, and leads to rich mathematical discourse [Hover: ways of representing, thinking, talking, agreeing, and disagreeing; the way ideas are exchanged and what the ideas entail; and as being shaped by the tasks in which students engage as well as by the nature of the learning environment].
The strengths of using Low Floor High Ceiling Tasks:
Examples of some Low Floor High Ceiling Tasks can be found at the following sites:
Math in 3-Acts was developed by Dan Meyer to spark an interest in and engage students in thought-provoking mathematical inquiry. Math in 3-Acts is a whole-group mathematics task consisting of three distinct parts:
Act One is about noticing and wondering. The teacher shares with students an image, video, or other situation that is engaging and perplexing. Students then generate questions about the situation.
In Act Two , the teacher offers some information for the students to use as they find the solutions to the problem.
Act Three is the “reveal.” Students share their thinking as well as their solutions.
“Math in 3 Acts” is a fun way to engage your students, there is a low entry point that gives students confidence, there are multiple paths to a solution, and it encourages students to work in groups to solve the problem. Some examples of Math in 3-Acts can be found at the following websites:
Number talks are brief, 5-15 minute discussions that focus on student solutions for a mental math computation problem. Students share their different mental math processes aloud while the teacher records their thinking visually on a chart or board. In addition, students learn from each other’s strategies as they question, critique, or build on the strategies that are shared.. To use a “number talk,” you would include the following steps:
“Number Talks” can be used as an introduction, a warm up to a lesson, or an extension. Some examples of Number Talks can be found at the following websites:
“This is easy.” Three little words that can have a big impact on students. What may be “easy” for one person, may be more “difficult” for someone else. And saying “this is easy” defeats the purpose of a growth mindset classroom, where students are comfortable making mistakes.
When the teacher says, “this is easy,” students may think,
Instead, you and your students could say the following:
Tracy Zager wrote a short article, “This is easy”: The Little Phrase That Causes Big Problems” that can give you more information. Read Tracy Zager’s article here.
Do you want your students to memorize concepts, or do you want them to understand and apply the mathematics for different situations?
What is a “worksheet” in mathematics? It is a paper and pencil assignment when no other materials are used. A worksheet does not allow your students to use hands-on materials/manipulatives [Hover: physical objects that are used as teaching tools to engage students in the hands-on learning of mathematics]; and worksheets are many times “naked number” with no context. And a worksheet should not be used to enhance a hands-on activity.
Students need time to explore and manipulate materials in order to learn the mathematics concept. Worksheets are just a test of rote memory. Students need to develop those higher-order thinking skills, and worksheets will not allow them to do that.
One productive belief from the NCTM publication, Principles to Action (2014), states, “Students at all grade levels can benefit from the use of physical and virtual manipulative materials to provide visual models of a range of mathematical ideas.”
You may need an “activity sheet,” a “graphic organizer,” etc. as you plan your mathematics activities/lessons, but be sure to include hands-on manipulatives. Using manipulatives can

Addition and subtraction, multiplication and division, equation-related mathematical problems, problem|definition & meaning.
A mathematical problem is an unsolved question . These problems usually provide some values and ask to find some unknown value . For example, if you cycled a total distance of 16 km in one hour, then what was your average speed? In other problems, you might have an equation already and need to solve it for the unknown variable e.g., what is the value of x in x + 6 = 21?
Some mathematical Problems include the usage of words , such as, “Jim maintained a speed of 30 kilometers per hour during the entire hour . How much ground did he cover?” Others use equations such as “If x + 19 = 78, what is x?” In this article, we shall talk about them in great detail.
Figure 1 – Problems in Mathematics
Word problems are notoriously difficult for pupils to master. Because there are so many moving parts in the process of solving word problems , it can be difficult to isolate the specific factor that is making things difficult for students.
Figure 2 – Types of Word Problems
There are three primary categories of problems involving addition and subtraction:
Any problem in which you begin with one quantity , acquire some more, and then finish with a greater quantity is said to be a joining problem. Any situation in which you begin with one quantity , remove some of that quantity , and then finish up with a smaller quantity is known as a separating problem. Take, for instance:
In each of these scenarios, the end outcome is unknown because we know how much we begin with, we know how much is joined or separated (the change), and now we need to determine how much is left over after the process . Both of these issues may be solved using the following straightforward pattern:
Students need to solve issues in which either the result, the change, or the starting point is unknown .
You’ll find that there are innumerable opportunities throughout the day to utilize the terminology of joining and separating! The most obvious of them is eating because your child is always considering joining other children in order to grab more of their food and then consuming that food after it has been obtained (separating).
When you play a game with your child that involves blocks, ask them to count how many are in their tower. Then you should ask them, “ Now I’ve added three more blocks to your tower . How many blocks do you currently have on your tower?” Have your child count the number of cars in a row while they see vehicles parked in a parking lot. Then pose the following question: “If two vehicles depart the parking lot, how many vehicles will be left?”
If your child is having trouble, you shouldn’t give them the solution. Instead, you should assist them in carrying out the action.
“You have 9 blueberries. Now you are going to devour four of them. When you consume those blueberries, what happens to the blueberries? Your kid might remark something along the lines of “They went in my stomach!” And you are able to reply, “Good.” So, those blueberries are still sitting there on your plate, are they?”
They will respond with a negative, at which point you can say, “Ok. So please display those blueberries that are disappearing from your dish. When performing an additive comparison, the problem might have the following forms, where x could be any whole number.
There are three primary kinds of word problems involving multiplication and division
When there is the same number of items in two different groups, we refer to such groupings as “equal groups.” Therefore, an equal number of items or things are grouped together in each equal group.
For example: If there are three boxes and you put five candies in each box, then there will be an equal number of candies in each box. At this point, we will assume that there ar e three equal groupings , each containing five candies .
The operations of multiplication and division can be represented by using rows and columns in an array. The rows denote the number of different categories. The number of items in each category, as well as their respective sizes, are denoted by the columns, although this is not necessarily a strict rule, and the two can be swapped.
It is essential for one to keep in mind that rows, which represent groups, are drawn horizontally, and columns, which represent the number of items in each group, are drawn vertically.
When doing a multiplicative comparison, the problem can involve expressions such as where x can be any whole number.
It is possible that the product, the size of the group, or the number of groups will all be unknown within each type of problem. Once again, we make use of counters to guide the students through the process of selecting the appropriate equation to apply while trying to solve the various kinds of issues.
The difference between issues involving addition and subtraction and problems involving multiplication and division should be brought to the attention of the students.
Students’ thinking and ability to solve problems are considerably improved when they are required to compose word problems in a fashion that is consistent with a certain word problem style. Because this is a considerably more difficult ability, the first time we practice composing word problems, we usually do so under the supervision of an instructor.
Equations are used to solve issues , and in order to solve a problem using equations, we must do two things:
One of the most notable characteristics of an algebraic solution is that the quantity that is being sought is incorporated into the very operation that is being performed. Because of this, we are able to construct a statement of the conditions in the same form as if the problem had already been solved.
Figure 3 – Equation Related Mathematical Problems
Nothing else has to be done at this point other than to simplify the equation and determine the total sum of the quantities that are already known. Because they are equivalent to the unknown quantity on the opposite side of the equation , the value of that is likewise determined, which means that the problem has been solved as a result.
These examples are quite literally examples of problems and illustrate the process of translating words into equations and then simplifying them to find the value of the unknown variable.
When a given integer is divided by 10, the sum of the quotient, dividend, and divisor equals 54. Determine the number that satisfies it.
Let x equal the desired number. Then:
(x / 10) + x + 10 = 54
x + 10x + 100 = 540
11x = 540 – 100
When a deal is made, a particular amount of profit or loss is realized by a merchant. In the second deal, he makes a profit of 250 dollars, but in the third, he loses 50 dollars. In the end, he determines that the three transactions resulted in a profit of one hundred dollars for him. In comparison to the first, how much ground did he make or lose?
In this particular illustration, the profit and the loss are of opposing characters, so it is necessary to differentiate between them using signs that are the opposite of one another. When the profit is a plus sign (+), the loss should be a minus sign (-).
Let’s say x equals the total amount needed.
The conclusion that follows from this is that x plus 250 minus 50 equals 100.
So, x = -100 .
The fact that the answer has a negative sign attached to it demonstrates that there was a loss incurred in the initial transaction; hence, the correct sign for x is also a negative sign. However, because this is dependent on the response, leaving it out of the calculation won’t result in an error at all.

5.1: Problem Solving An introduction to problem-solving is the process of identifying a challenge or obstacle and finding an effective solution through a systematic approach. It involves critical thinking, analyzing the problem, devising a plan, implementing it, and reflecting on the outcome to ensure the problem is resolved.
The very first Mathematical Practice is: Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of ...
Mathematician George Pólya's book, "How to Solve It: A New Aspect of Mathematical Method," written in 1957, is a great guide to have on hand.The ideas below, which provide you with general steps or strategies to solve math problems, are similar to those expressed in Pólya's book and should help you untangle even the most complicated math problem.
Mathematical processes include problem solving, logic and reasoning, and communicating ideas. These are the parts of mathematics that enable us to use the skills in a wide variety of situations. It is worth starting by distinguishing between the three words "method", "answer" and "solution". By "method" we mean the means used to get an answer.
Brief. Problem solving plays an important role in mathematics and should have a prominent role in the mathematics education of K-12 students. However, knowing how to incorporate problem solving meaningfully into the mathematics curriculum is not necessarily obvious to mathematics teachers. (The term "problem solving" refers to mathematical ...
Problem solving is the goal of mathematics. Problem solving is a means of learning mathematics. Problem solving is a challenging and complex process, requiring the use of higher order thinking skills that lead to deeper understanding of meaningful mathematical concepts. Problem solving is not practicing a skill.
Here are five strategies to help students check their solutions. 1. Use the Inverse Operation. For simpler problems, a quick and easy problem solving strategy is to use the inverse operation. For example, if the operation to solve a word problem is 56 ÷ 8 = 7 students can check the answer is correct by multiplying 8 × 7.
A math problem is a problem that can be solved, or a question that can be answered, with the tools of mathematics. Mathematical problem-solving makes use of various math functions and processes.
The problem-solving process can be described as a journey from meeting a problem for the first time to finding a solution, communicating it and evaluating the route. There are many models of the problem-solving process but they all have a similar structure. ... Functional maths requires learners to be able to use mathematics in ways that make ...
Key Takeaways. Effective problem solving involves critical and creative thinking. The four steps to effective problem solving are the following: Define the problem. Narrow the problem. Generate solutions. Choose the solution. Brainstorming is a good method for generating creative solutions.
Therefore, the way in which the problem solving question is presented in assessment is important. The value in terms of problem solving will be diminished if, for example: (1) the task within the question is very familiar to the student; (2) the mathematical methods are identified explicitly in the question; (3) the question is highly scaffolded.
The problem with both keywords and the rote-step strategies is that both methods try to turn something that is inherently messy into an algorithm! It's way past time that we leave both methods behind. First, we need to broaden the definition of problem-solving. Somewhere along the line, problem-solving became synonymous with "word problems."
Problem solving is not necessarily just about answering word problems in math. If a child already has a readily available method to solve this sort of problem, problem solving has not occurred. Problem solving in math is finding a way to apply knowledge and skills you have to answer unfamiliar types of problems.

A Problem Solving Strategy: Find the Math, Remove the Context. Sometimes the problem has a lot of details in it that are unimportant, or at least unimportant for getting started. The goal is to find the underlying math problem, then come back to the original question and see if you can solve it using the math.
Polya defined problem solving as. finding "a way where no way is known, off-hand... out of a difficulty...around an obstacle". (1949/1980, p. 1). Polya stated that to know mathematics is to solve problems. The difference between nonroutine and routine problems seems to be a key element in.
