Where Year 2 fits

In Year 2 the headline event arrives: the first times tables. Still in Phase 1, children step past 100, start thinking in hundreds-tens-ones, and push their instant facts out to 20. Remember the golden rule of the refreshed curriculum: it's progression-based — children move on when they're ready, not on a birthday. Treat year levels as a guide only.

What children learn in Year 2 Number

Children read, write and order numbers to 120 and unpack three-digit place value (hundreds, tens, ones). They count in 2s, 3s, 5s and 10s, round to the nearest 10, and memorise the addition and subtraction facts to 20. Multiplication gets real: arrays (rows and columns), the link between skip-counting and times tables, and memorising the ×÷ facts for 2s, 5s and 10s. Fractions grow to thirds (and equivalents like 2/4 = 1/2), and children combine coins and notes into totals.

Five ways to help at home 🏡

1. Spot arrays in the wild

Egg cartons, muffin trays, chocolate blocks: 'Two rows of 5 — how many?' Arrays are how the curriculum introduces multiplication.

2. Link skip-counting to tables

They already count 5, 10, 15… show them that's the 5 times table wearing a disguise. '4 fives — count it: 5, 10, 15, 20.'

3. Practise facts in tiny bursts

Two minutes, a few facts, most days. Quick and cheerful beats long and grim — the goal is instant recall, not endurance.

4. Round when you shop

'That's $38 — about how many tens is that?' Rounding to the nearest 10 is a Year 2 skill and supermarkets are free practice.

5. Build numbers past 100

Say a number like 117 and ask: how many hundreds, tens, ones? Then swap — you build, they name. Three-digit place value clicks fast this way.
