Square and cube numbers
Use integer powers and associated real roots (square, cube, and higher); recognise powers of 2, 3, 4, and 5; distinguish between exact representations of roots and their decimal approximations

Square and cube numbers means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Place-value grid (ones / tenths / hundredths); Pencil. 1. Say the goal of Square and cube numbers in plain words once. 2. Adult shows 0.3 as three tenths on the grid. 3. Child builds three decimal amounts on the grid and reads them aloud. 4. Fresh check: one fresh tenths/hundredths reading. Record and stop. Done: three correct decimal readings. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Calculate squares, cubes, and higher integer powers of whole numbers
- Find square roots and cube roots of perfect squares and perfect cubes
- Recognise key powers (powers of 2 up to 2¹⁰, powers of 3 up to 3⁵, etc.) and distinguish exact roots from approximations
“Can your child work out that √25 = 5 and ∛27 = 3 — knowing these are the inverse of squaring and cubing — and say whether √50 is closer to 7 or 8?”
