Excerpt

Student Information Card

Guess and Check Strategy

The Guess and Check strategy can be helpful for many types of problems. When you use this strategy you will need to make a reasonable guess, based on the information that you have been given, check your guess and check again if necessary. When you check, your guesses should get closer and closer to the answer, until you reach the correct answer itself.

Example: Paul is 12 years old and his mom is three times as old.
How many years must pass before his mom is twice as old?

1. What do you know already?

You know that Paul is 12 and his mom is 3 times as old as Paul, which
must mean that Paul’s mom is 36 years old (3 x 12 = 36).

2. Make a guess.

4 years must pass.

In 4 years time Paul will be 16 and Paul’s mom will be 40. Your guess is
not correct because 40 is not twice or double 16.

4. Make a guess.

10 years must pass.

In 10 years time Paul will be 22 and Paul’s mom will be 46. Your guess is
not correct because 46 is not twice 22 (but getting closer).

6. Make a guess.

12 years must pass.

In 12 years time Paul will be 24 years old and Paul’s mom will be 48. Your
answer is correct since 48 is twice 24.

8. Correct Solution.

Does your solution answer the question? Yes. 12 years must pass before
Paul’s mom is twice as old as Paul.
