Set out your lesson

Bring to the table
- 8 large blocks or drawings
- A bowl or mat labeled “taken away”
Full guide and materials
- 8 large blocks or drawings
- A bowl or mat labeled “taken away”
- Step 1. Start with 8 blocks and count them together.
- Step 2. Say, “We take away 3.” Move 3 blocks onto the taken-away mat.
- Step 3. Count the blocks that remain and say “8 take away 3 leaves 5.”
- Step 4. Repeat with a smaller start, such as 5 take away 2.
- Step 5. Let your child move the taken-away objects for one problem and state how many are left.
- Quick check. Start with a visible set, remove a stated number, and ask how many are left. Success means your child gives the correct remainder after the removal.
Worked example. Start with 8, move 3 to the taken-away mat, and count 5 remaining.
Optional challenge. Start with 7 and separate 2. Ask how many are in the larger remaining group and have your child explain the take-away action.
What to notice. Save a parent note with the starting number, the number taken away, and the remaining count.

Check understanding
- Model 'taking away' with physical objects and say how many remain
- Act out a 'take from' situation (e.g. 5 biscuits, eat 2, how many left?)
- Explain that subtraction means finding how many are left
“If your child has 9 biscuits and eats 3, do they understand that subtracting means taking some away — and can they tell you 6 biscuits are left?”
