What to notice
Multiply 6 by an even number and the answer ends in that same digit: 6 × 2 = 12, 6 × 4 = 24, 6 × 6 = 36, 6 × 8 = 48. Children enjoy spotting this echo, and it pins down four facts at once.
Every answer in the 6s is even, and every one is also in the 3s, because 6 is two 3s. So an odd answer is always wrong, and the digits add to 3, 6 or 9: for 42 it is 4 + 2 = 6, for 54 it is 5 + 4 = 9.
By the time your child reaches the 6s, turnarounds have already given them a lot. 6 × 1, 6 × 2, 6 × 3, 6 × 4, 6 × 5, 6 × 9 and 6 × 10 are in tables they have met. The new facts are mostly 6 × 6, 6 × 7, 6 × 8 and 6 × 12, which is a much shorter list.
How to practise at home
- Practise “five and one more” on paper: draw five rows of 7 dots, then one more row in a different colour. Seeing the extra row makes the strategy obvious.
- Make 6 × 6 = 36 a landmark. From there, 6 × 7 is one more 6, which is 42, and 6 × 5 is one fewer, which is 30.
- An egg carton is two rows of 6. Two cartons is 2 × 6 eggs, three cartons is 3 × 6. Counting egg cups is a nice way to see the 6s.
- Use the drill on this page and note which facts are slow. If 6 × 7 and 6 × 8 are, say them a few extra times each day for a week, then drill again.
Slips to watch for
- Mixing up 6 × 7 and 6 × 8, answering 48 for 6 × 7 or 42 for 6 × 8. The echo helps: 6 × 8 has to end in 8.
- Adding one instead of one more group: going from 5 × 7 = 35 to 36 instead of 42. Ask what “one more group of 7” looks like.
- Losing the thread in 6 × 12. Split it as 6 × 10 = 60 and 6 × 2 = 12, then 60 + 12 = 72.
