Real-life hook
A six-pack holds 6 drinks. How many in 4 packs? 6 × 4 = 24. If you know your 5 times table, you're almost there already.

The idea
Build ×6 from ×5: 6 × a number is 5 × the number, plus one more group. 6 × 4 = (5 × 4) + 4 = 20 + 4 = 24.
Worked examples
6 × 4 = 24
- 5 × 4 = 20.
- Add one more 4: 24.
6 × 7 = 42
- 5 × 7 = 35.
- Add one more 7: 42.
Common mistake
Watch out: Forgetting to add the extra group after ×5.
Better: ×6 = ×5 then add one more group: 6 × 7 = 35 + 7 = 42.
Use it in real life
Six eggs per row, 4 rows in the tray: 6 × 4 = 24 eggs.
