### PROBLEM-SOLVING STRATEGIES

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