Challenges – only answer question numbers listed for your chosen challenge

• Ref Ch: print Day 2 Ref CH Digit Cards (or you can easily make your own) – shuffle the cards and turn over 2 numbers. Use these to create two 1decimal place numbers. For example: if you turn over a 3 and a 7 that would give you 0.3 and 0.7. Subtract the smaller number from the larger number: 0.7 – 0.3 = 0.4. Repeat 10 times.
• Ch1: complete questions: 1 (a&b), 2, 3, 4 (a&b) & 6 on Day 2 Worksheet and check your answers using Day 2 Worksheet Answers.

Extension: watch https://studio.youtube.com/video/ZH84yMAEn84/edit – in the video, Mrs Pearson chooses some three-decimal numbers below 1 whole and carries out some calculations which lead to a surprising result! What do you notice?
Can you figure out the steps that Mrs Pearson carries out in each calculation? Try it for yourself using your own decimal numbers – take care that the tenths and thousandths digits are different.

Day 3: totalling one whole

LI: to find the complements which sum to make 1

Watch “Lesson 3 - Complements to 1” video: https://whiterosemaths.com/homelearning/year-5/

Challenges – only answer question numbers listed for your chosen challenge

• Ref Ch: open Day 3 Ref Ch – find pairs using hundred grids. Answers are on the second page.
• Ch1: Using digit cards (use Day 2 Ref CH Digit Cards), shuffle the cards and turn over two cards.  Use these to create a 2 decimal place number.  Record that number and find its complement to make 1 whole.

e.g. 1 & 5 could become either 0.15 or 0.51. If 0.15, then its complement would be 0.85 BUT if 0.51 it would pair with 0.49 to make 1.0

• Ch2: complete questions: 1, 2, 3, 4, 5 & 6 from Day 3 Worksheet and check your answers using Day 3 Worksheet Answers.
