The 2s, 5s, and 10s: Your First Times Tables!
For grown-ups
Companion summary
Have you ever noticed how counting money or sharing sweets always seems to follow a secret pattern? Knowing your 2s, 5s, and 10s helps you add up coins, split things fairly, and save loads of time every day. Here is a brilliant trick: the 10 times table is just any number with a zero added on the end. When these feel easy, try spotting how the 5 times table is exactly halfway between two answers in the 10 times table.

Look at these numbers: 2, 4, 6, 8, 10. Now look at these: 5, 10, 15, 20, 25. And these: 10, 20, 30, 40, 50. Do you spot a pattern in each row? Each row is a counting sequence — you are adding the same number each time. That is exactly what times tables are: counting in equal steps!
