1.  I can use word clues to help me work out operations and steps in word problems From AusVELS Level 5: Number and Algebra: Apply a range of strategies to solve realistic problems GOAL AUSVELS LEVEL 5: NUMBER AND ALGEBRA

2. APK Look at your notes on the 4 operations lesson- share 3 important clues

3. NEW INFORMATION To solve written maths problems you often must decide whether to add, subtract, multiply or divide.

4. NEW INFORMATION (PLACE IN BOOKS) To solve written maths problems you often must decide whether to add, subtract, multiply or divide. Turn and Talk: What clues do I look for to know which operation to use?

5. NEW INFORMATION (PLACE IN BOOKS) To solve written maths problems you often must decide whether to add, subtract, multiply or divide. The clues for which operation/s to use is in the wording- what words do you recall from our 4 operations lesson?

6. NEW INFORMATION (PLACE IN BOOKS) Example 1: When putting together their money to buy a Mother’s Day present three children needed a total of $149. Fred had $52 and Mary had $65. How much did Billie need to put in to buy the present? HOW MANY PROBLEMS NEED TO BE SOLVED HERE?

7. NEW INFORMATION STEP 1: ADD Fred and Mary had $52 + $65 = $117

8. NEW INFORMATION Fred and Mary had $52 + $65 = $117 $117 + (?HOW MUCH BILLY NEEDS TO PAY)=$149 Use inverse operation! STEP 2: SUBTRACT We need to subtract $117 from $149 to find out how much Billie needed to pay.

9. NEW INFORMATION Fred and Mary had $52 + $65 = $117 We need to subtract $117 from $149 to find out how much Billie needed to pay. $149 - $117 = $32

10. NEW INFORMATION (PLACE IN BOOKS) Fred and Mary had $52 + $65 = $117 We need to subtract $117 from $149 to find out how much Billie needed to pay. $149 - $117 = $32 In this problem you needed to add and subtract.

11. NEW INFORMATION (PLACE IN BOOKS) Example 2: 57 students each paid $9 to go to the zoo. Their 11 teachers and parents paid $12 each. a.How much did they pay altogether? b.How much more did the students pay than the teachers and parents? HOW MANY PROBLEMS NEED TO BE SOLVED HERE?

12. NEW INFORMATION a. We must multiply 57 by 9 and 11 by 12 and then add the answers.

13. NEW INFORMATION a. We must multiply 57 by 9 and 11 by 12 and then add the answers. One way to do this is –

14. NEW INFORMATION a. We must multiply 57 by 9 and 11 by 12 and then add the answers. One way to do this is – 57 x $9 = 50 x $9 + 7 x $9 = $450 + $63 = $513

15. NEW INFORMATION a. We must multiply 57 by 9 and 11 by 12 and then add the answers. One way to do this is – 57 x $9 = 50 x $9 + 7 x $9 11 x $12 = 10 x $12 + 1 x $12 = $450 + $63 = $120 + $12 = $513 = $132

16. NEW INFORMATION a. We must multiply 57 by 9 and 11 by 12 and then add the answers. One way to do this is – Step 1. Step 2. 57 x $9 = 50 x $9 + 7 x $9 11 x $12 = 10 x $12 + 1 x $12 = $450 + $63 = $120 + $12 = $513 = $132 Step 3. $513 + $132 = $645

17. NEW INFORMATION (PLACE IN BOOKS) a. We must multiply 57 by 9 and 11 by 12 and then add the answers. One way to do this is – 57 x $9 = 50 x $9 + 7 x $9 11 x $12 = 10 x $12 + 1 x $12 = $450 + $63 = $120 + $12 = $513 = $132 $513 + $132 = $645 They paid $645 in total

18. NEW INFORMATION b. We must subtract the amount the teachers and parents paid from the amount the students paid.

19. NEW INFORMATION b. We must subtract the amount the teachers and parents paid from the amount the students paid. 4. $513 - $132 = $381

20. NEW INFORMATION (PLACE IN BOOKS) b. We must subtract the amount the teachers and parents paid from the amount the students paid. $513 - $132 = $381 The students paid $381 more.
