Problem solving strategies

PROBLEM-SOLVING STRATEGIES

7TH GRADE MATH


Draw a picture

DRAW A PICTURE

  • When problems involve objects, distances, or places you can draw a picture to make the problem easier to understand.

  • You will often use your picture to solve the problem.


Use concrete models

USE CONCRETE MODELS

  • If a problem involves objects, you can sometimes make a model using (or drawing) those objects to act out the problem.


Guess and check

GUESS AND CHECK

  • If you do not know how to solve a problem, you can always make a guess.

  • Then check your guess using the information in the problem.

  • Use the result to make a better guess.

  • Repeat until you find the correct answer.


Work backwards

WORK BACKWARDS

  • Some problems give you a sequence of information and ask you to find something that happened at the beginning.

  • To solve a problem like this, you may want to start at the end of the problem and work backwards.


Find a pattern

FIND A PATTERN

  • In some problems, there is a relationship between different pieces of information.

  • Examine this relationship and try to find a pattern.

  • You can then use this patter to find more information and the solution to the problem.


Make a table

MAKE A TABLE

  • When you are given a lot of information in a problem, it may be helpful to organize that information.

  • One way to organize information is to make a table.


Solve a simpler problem

SOLVE A SIMPLER PROBLEM

  • Sometimes a problem contains large numbers or requires many steps.

  • Try to solve a simpler problem that is similar.

  • Solve the simpler problem first, and then try the same steps to solve the original problem.


Determine a reasonable answer

DETERMINE A REASONABLE ANSWER

  • In some problems, it is possible to find the correct answer by determining which answers could make sense in the situation.

  • Estimate or use mental math skills to determine a reasonable answer.


Act it out

ACT IT OUT

  • Some problems involve actions or processes.

  • To solve these problems, you can act it out.

  • Actively modeling the problem can help you find the solution.


Make an organized list

MAKE AN ORGANIZED LIST

  • In some problems, you will need to find how many different ways something can happen.

  • It is often helpful to make an organized list.

  • This will help you count the outcomes and be sure that you have included all of them.
