Sometimes it can be difficultto figure out what to do when
you are faced with a word problem.
We will use the UNRAAVEL method to figure this out!

Pedro rode 19 miles on his bicycle last week. This week,
he rode 10 less miles than last week. What is 10
less than 19?

N = Now Predict
What Do You ThinkYou 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
or subtract?
• Are there any hints that you may need
to estimate?

I predict that I will need to SUBTRACT.
I saw the words: HOW MANY MOREin the question.

V = Verify Your Answer. (Is it reasonable? Does it make
sense?)28 IS reasonable
because it is smaller
than 46. It would make sense to have
this amount left after finding the
difference of 46 and 18.
