Sometimes it can be difficultto figure out what to do whenyou are faced with a word problem. We will use the UNRAAVEL method to figure this out!
U = Underline the question Find the question and Underline it! 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? We are going to practice UNRAAVEL with this one! Wally had 18 basketball cards. He had 46 baseball cards. How many more baseball cards than basketball cards did Wally have? Tammy is 2 years holder than Kurt. Kurt is 4 years younger than Hal. Hal is 9 years old. How old is Tammy? Joey gets on the school bus at 3:30. The ride from school to home takes 30 minutes. At what time did Joey get home?
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 MORE in the question.
R = Readthe Word Problem Read the entire problem!!!
Read it, Dudes and Dudettes! Wally had 18 basketball cards. He had 46 baseball cards. How many more baseball cards than basketball cards did Wally have?
A = Are the Important Words Circled? (especially the clue words?) Wally had 18 basketball cards. He had 46 baseball cards. How many more baseball cards than basketball cards did Wally have?
A = Apply the Steps You Chose to Solve the Problem 46 Baseballcards - 18 Basketball cards HOW MANY MORE Is a key word to subtract
3 16 Baseballcards 46 - 18 28 Basketball cards Difference
V = Verify Your Answer. (Is it reasonable? Does it make sense?) 28IS reasonable because it is smaller than 46. It would make sense to have this amount left after finding the difference of 46 and 18.
E = EliminateWrong Answers. a. 64 b. 32 c. 48 d. 28 Too big. Didn’t regroup. Too big.
L = Letthe answer stay or rework the problem I got that one correct, but I may have to rework the next one!
How do you UNRAAVEL? Underline the question Now predict what you think you need to do to solve the problem Read the word problem Are the important words circled? (especially clue words) Apply the step(s) you chose to solve the problem Verify your answer (is it reasonable; does it make sense?) Eliminate wrong answers Let the answer stay or rework the problem Double check your work!
Awesome Job DO YOUR BEST ON THE TEST!
