Maths Year 2 Autumn Multiplication and Division

Each unit has everything you need to teach a set of related skills and concepts.

Understand multiplication as sets (suggested as 2 days)

Planning and Activities

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.

You Will Need

Mental/Oral Maths Starters

Day 1
Count in 2s (pre-requisite skills)

Suggested for Day 2
Count in 10s (simmering skills)

Worksheets

Day 1
Children continue to reason about number patterns, counting in 2s and 10s.

Day 2
Children work out how many 2ps (to 24p) or 10ps (to 90p) are needed to pay for items in a shop.

Mastery: Reasoning and Problem-Solving

  • What comes next?
    34 + 10 = 44
    44 + 10 = 54
    54 + 10 = 64
  • Circle the number which does not belong in each sequence:
    12, 14, 16, 18, 19, 22, 24
    60, 50, 40, 30, 12, 10, 0
    17, 19, 22, 23, 25, 27, 29
  • How many lots of 10 in 40?
    14 is how many 2s?
    There are ☐ tens in 90.
    2 × 10p = 20p; 10 × 2p = 20p What do you notice?
  • Count in 10s to 70. How many numbers have you said?
    Count in 2s to 16. How many numbers have you said?


In-depth Investigation: Clapping Times
If you count from 1 to 20 and clap more loudly on the numbers in the two times table, as well as saying those numbers loudly, which numbers will be loud? Clapping Times from nrich.maths.org.
