LESSON 5: PROBLEM- SOLVING: MATH By Junli Kasper Fifth Grade Problem.

Why learn how to solve word problems? Because we need to use math to find answers in every-day life.

To solve word problems easily, we need to follow these steps: U = Underline the question Find the question and Underline it! Find the question and Underline it! 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? Sid has $ He bought two a poster for $5.69. How much money did he have left after his purchases? 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? 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?

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!!!!

A = Are the Important Words Circled? ( especially the clue words?) Sid has $ 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 $28.00 $ $33.69 Video Games Video Games Plus Poster Total Amount Spent

Sid has $ 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?Sid has $ 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?

$ $16.31 Sid’s Money What he spent Leftover!

V = Verify Your Answer. (Is it reasonable? Does it Make Sense?) $16.31 IS reasonable because it is smaller than $ 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. Can’t End in two Zeroes.

L = Let the Answer Stay or Rework the Problem I got that one correct, but I may have to rework the next one!

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