Maths Year 2 Summer Number, Fractions, Money

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

Count 2s, 3s, 5s, 10s; multiples of 2, 5, 10 (suggested as 2 days)

Planning and Activities

Day 1 Teaching
Count in 2s to 50, marking the 2s on Number Grid ITP. Mark 2s from 52 to 100 using the (stripes) pattern. Repeat to count in 5s; spot the pattern. Note multiples of 2 and 5 (10s). Count on in 3s, noting which numbers which are also multiples of 2 (6x table) and 5 (15, 30, 45). Which is a multiple of 2, 3 and 5? (30)
Group activities
-- Practise counting in 2s, 3s, 5s and 10s using an online activity.
-- Spot multiples of 2s, 3s, 5s or 10s by playing ‘waving multiples’.

Day 2 Teaching
Use ITP Number Grid to highlight the count in 3s. We are counting on in 3s, adding 3 each time, so 3 + 3 is 6, 6 + 3 is 9, 9 + 3 is 12. These are multiples of 3. Note the pattern. Add the digits of each multiple of 3 in turn and show that these always add to 3 or 6 or 9 – our mathematical test to check if any number is a multiple of 3: finding the digit sum of the number. Try this for some big numbers, e.g. 123, 412, 339 and 450.
Group activities
Use the ‘Mixed Bags’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Hop in 3s along a beaded line, recording the corresponding multiplication.
-- Roll a dice; ‘collect’ corresponding bunches of 3 bananas. Record the corresponding multiplication.

You Will Need

  • ITP Number grid

Mastery: Reasoning and Problem-Solving

  • Write the missing numbers in each sequence:
    24, 26, 28, ☐, ☐, ☐
    10, ☐, ☐, ☐, 30, 35
    36, 33, 30, ☐, ☐, ☐
  • Sam counts in 3s.
    He starts at 3.
    Write the first six numbers he says.
    Write the 12th number he says.
    What number does he say before he says 51?
  • Tariq starts counting in 3s and Amir starts counting in 10s. What is the first number they will both say?

In-depth Investigation: Mixed Bags
Children look for multiples of 2p and 5p, then 3p and 5p with given totals to solve a problem.
