### PROBLEM-SOLVING STRATEGIES

7TH GRADE MATH

• 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.

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

• 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

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.
