Maths Year 2 Summer Revision

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

Revision: addition and subtraction (suggested as 3 days)

Planning and Activities

Day 1 Teaching
Show children 42 + ☐ = 46. Children discuss in pairs what they think the hidden number might be. Repeat with the box in first position. Hide 10 pegs behind a cloth. Remove 7 pegs so children can see the 7 pegs, then remove the cloth to show how many are left. Write ☐ – 7 = 3. How many pegs do you think were on the coat hanger to begin with? Repeat, hiding either the first or second a number in calculations such as: 60 + 30 = 90, 37 + 40 = 77, 47 – 5 = 42, 84 – 20 = 64.
Group Activities
-- Support children with identifying the mystery numbers.

Day 2 Teaching
Show a 0 to 100 landmarked line. Ask two children up to mark on 72 and 57, and explain how they decided where to mark them. Use Frog to work out 72 – 57. Model drawing own line for Frog. Repeat for other subtractions, e.g. 84 – 65, 64 – 48.
Group Activities
-- Support children in drawing their own lines for Frog.
-- Use digit cards to make 2-digit subtractions – choose which strategy to use to work out the answer.

Day 3 Teaching
Display: Chloe has 7 stickers. Zak has 11 stickers. How many more stickers does Zak have than Chloe? Ask children to read it, and then discuss with a partner. Sketch a line of 7 smiley faces and 11 smiley faces directly underneath. Point to the 4 extra faces. So, this number story is asking us to find the difference between 7 and 11, which is 4! Repeat with other word problems.
Group Activities
-- Support children in understanding the number story before identifying the necessary calculation.

Mastery: Reasoning and Problem-Solving

  • Use four different numbers from this list to complete the number sentences below.
    5, 15, 25, 35, 45, 55
    ☐ + ☐ = 60
    ☐ + ☐ = 60
  • Write the missing number in the box.
    10 + ☐ = 16 + 3
    32 + 6 = 40 - ☐
  • Poppy and Jay count cars. Poppy counts 37 red cars. Jay counts 24 blue cars. How many cars do they count altogether?
  • There are 65 cakes. 15 boys and 29 girls each take a cake. How many cakes are left?
  • Peta buys a cake for 73p and pays with £1. How much change should she get?
