Week 9 Reflection

The coming storm is my writing that I have been working on
Exercise 7 This is my Numeracy follow up I am learning to

What to do   

Use the information given to you to derive the answer to a similar problem.

1. If 2 × 25 = 50 what is 2 × 24 ?48
2. If 4 × 25 = 100 what is 4 × 27 ?108
3. If 3 × 15 = 45 what is 3 × 14 ?42
4. If 4 × 15 = 60 what is 4 × 17 ?68
5. If 6 × 15 = 90 what is 6 × 14 ?56
6. If 2 × 25 = 50 what is 2 × 26 ?52
7. If 4 × 25 = 100 what is 4 × 24 ?96
8. If 3 × 15 = 45 what is 3 × 16 ?48
9. If 4 × 15 = 60 what is 4 × 13 ?56
10. If 6 × 15 = 90 what is 6 × 17 ?102

Exercise 8

What to do   

Use the strategy add a little/subtract a little to solve these problems.  

Julie wanted to find 3 × 28.

She knows that 28 is near 30, so she used 3 × 30 = 90 and subtracted 3 × 2 = 6 to get the answer.  

Julie recorded this in her maths book

3 × 28 = 90 – 6 = 84

Using Julie’s method find the answer to the following problems.  Record your working like Julie did.

1) 4 × 19  76 (2) 3 × 41 13 (3) 5 × 59 259

4) 7 × 52 310         (5) 4 × 73 289         ( 6) 3 × 37 97

7) 6 × 102 612       (8) 5 × 301 151 (9) 4 × 698 298

10) 3 × 499 1299 (11) 7 × 602 422 (12) 9 × 3999 35991

WALT: Comprehend what I read.I  have learnt what we use water for and how we can use water.
