### Teaching and Group Activities for Understanding

**Day 1 Teaching**Launch Number grid ITP and click on multiples of 10. They all end in zero. Spot really large multiples of 10. Reset grid and click to show multiples of 2. Study the pattern here. Identify multiples of 2. Then look at patterns in odd numbers.

**Group activities**

Use the in-depth problem-solving investigation ‘Clapping Times’ from NRICH as today’s group activity.

Or, use these activities:

**-- Continue number patterns, using knowledge and understanding of counting in 2s and 10s.**

**Day 2 Teaching**Show children 10p coins and count in 10s to 70p. Point out that we can write a repeated addition of 10p + 10p + 10p etc. but we can write 7 × 10p = 70p. This means seven lots of 10p. Repeat with other numbers of 10p coins, then with numbers of 2p coins.

**Group activities**

-- Apply knowledge and understanding of counting in 10s and 2s to money. Begin to write number sentences using the multiplication sign.
