Presentation Transcript

### PROBLEM-SOLVING STRATEGIES

7TH GRADE MATH

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.

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

- 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

- 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.
