Week 8 Reflection


WALT: Create a water cycle                                                                                                                       I have learnt how the water cycle actually works. I also learnt what Precipitation, Condensation and Evaporation means.

Exercise 1
What to do   
Use the information given to you to derive the answer to a similar problem.
  1. If 9 × 20 = 180 what is 9 × 21 ? 189
  2. If 8 × 30 = 240 what is 8 × 31 ? 248
  3. If 4 × 40 = 160 what is 4 × 42 ? 168
  4. If 5 × 50 = 250 what is 5 × 51 ? 255
  5. If 3 × 60 = 180 what is 3 x 62 ? 186
  6. If 2 × 70 = 140 what is 2 × 73 ? 146
  7. If 4 × 80 = 320 what is 4 × 82 ? 328
8)    If 2 × 90 = 180 what is 2 × 94 ? 188
Exercise 2
What to do   
Use the information given to you to derive the answer to a similar problem.
1) If 9 × 20 = 180 what is 9 × 19 ? 171

3) If 7 × 40 = 280 what is 7 × 39 ? 273
4) If 5 × 50 = 250 what is 5 × 49 ? 245
5) If 3 × 60 = 180 what is 3 × 58 ? 174
6) If 2 × 70 = 140 what is 2 × 67 ? 134
7) If 4 × 80 = 320 what is 4 × 78 ? 312
8) If 2 × 90 = 180 what is 2 × 86 ? 172
Exercise 3
What to do   
Use the information given to you to derive the answer to a similar problem.
  1. If 9 × 20 = 180 what is 9 × 22 ? 198
  2. If 7 × 30 = 210 what is 7 × 32 ? 224
  3. If 5 × 40 = 200 what is 5 × 43 ? 215
  4. If 4 × 50 = 200 what is 4 × 51 ? 204
  5. If 3 × 60 = 180 what is 3 × 61 ? 183
  6. If 6 × 70 = 420 what is 6 × 73 ? 438
  7. If 6 × 80 = 480 what is 6 × 81 ? 486
8)    If 8 × 90 = 720 what is 8 × 92 ? 736

  2. If 7 × 40 = 280 what is 7 × 37 ? 259
  3. If 5 × 40 = 200 what is 5 × 38 ? 190
  4. If 4 × 50 = 200 what is 4 × 47 ? 188
  5. If 3 × 60 = 180 what is 3 × 56 ? 168
  6. If 6 × 70 = 420 what is 6 × 67 ? 402

8)    If 8 × 90 = 720 what is 8 × 88 ? 704
WALT: round up numbers to make them easier to solve
I learnt how to work out some really hard problems.


WALT: Become great bloggers
This year I have learnt how to copy a piece of work from a Google doc to a new blog post

    Wow, Reagan! This maths is really complicated and you have learnt this strategy quickly. I am really proud of how you came straight home and finished your water cycle work that you hadn't completed in class. I love watching you on my Chromebook at home and seeing how many skills you have learnt so far this year.
    Love Mum
