UNRAAVEL a Math Problem

- Sure-Fire Steps to Becoming a Math Genius!

UNRAAVEL Strategy presented by Larry I. Bell.

Taken from Area 6 ALTs

Fourth and Fifth Grade Problem.

Sometimes it can be difficult to figure out what

to do when you are faced with a word problem.

- Even Albert Einstein said
- Do not worry about your difficulties in

Mathematics. I can assure you mine are still

greater.

If he had known about UNRAAVEL..

- ..he may have been able to do even more with

Math! - Are you ready to learn how to UNRAAVEL a math

problem?

U Underline the question

Allison is buying five sets of markers for each

of her twelve art students. If each set of

markers costs 5.75, how much will she spend on

markers?

- Find the question and Underline it!

Sid has 50.00. He bought two video games that

cost 14.00 each. He also bought a poster for

5.69. How much money did he have left after his

purchases?

We are going to practice UNRAAVEL with this one!

The soccer team scored six times as many goals

during the regular season as they did during

playoffs. The team scored forty-two goals during

the regular season. How many goals were scored

during the playoffs?

The students are asked to put their booth fifteen

feet from the entry way on the path to the

parking lot. The parking lot is sixty-two feet

from the entry way. How far is their booth from

the parking lot?

N Now Predict What Do You Think You Need to

Do to Solve the Problem?

- Do you think the answer will be larger or

smaller? Do you think you will need to add,

subtract, multiply, or divide? Are there any

hints that you may need to estimate?

I predict that I will need to subtract. I saw

the words HAVE LEFT in the question.

R Read the Word Problem

- Read the
- entire problem!!!!

Read it, Dudes and Dudettes!

Sid has 50.00. He bought two video games that

cost 14.00 each. He also bought a poster for

5.69. How much money did he have left after his

purchases?

A Are the Important Words Circled? (especially

the clue words?)

- Sid has 50.00. He bought two video games that

cost 14.00 each. He also bought a poster for

5.69. How much money did he have left after his

purchases?

A Apply the Steps You Chose to Solve the Problem

- 14.00
- X 2

Video Games

28.00

Video Games Plus Poster

28.00 5.69

33.69

Total Amount Spent

- Sid has 50.00. He bought two video games that

cost 14.00 each. He also bought a poster for

5.69. How much money did he have left after his

purchases?

Sids Money

- 50.00
- - 33.69

16.31

What he spent

Leftover!

V Verify Your Answer. (Is it reasonable?

Does it Make Sense?)

16.31 IS reasonable because it is smaller than

50.00. It would make sense to have this amount

left after buying games and a poster.

E Eliminate Wrong Answers.

- a. 66.31
- b. 15.00
- c. 55.76
- d. 16.31

Too big.

Cant End in two Zeroes.

Too big.

L Let the Answer Stay or Rework the Problem

I got that one correct, but I may have to rework

the next one!

How do you UNRAAVEL?

- U nderline the question
- N ow predict what you think you need to do to
- solve the problem
- R ead the word problem
- A re the important words circled?
- (especially clue words)
- A pply the step(s) you chose to solve the problem
- V erify your answer (is it reasonable does it
- make sense?)
- E liminate wrong answers
- L et the answer stay or rework the problem
- ?Double check your work!
