10 times table
The simplest table thanks to place value: every answer is the digit shifted left with a 0 added.
The 10 times table is straightforward and exposes children to the most powerful idea in number: multiplying by 10 shifts every digit one place to the left and a zero is added in the ones column.
Worked examples
1×10=10, 2×10=20, 3×10=30 ... 10×10=100, 11×10=110, 12×10=120.
To ×10 any whole number: add a zero. 7 × 10 = 70. 23 × 10 = 230.
Decimals: 0.4 × 10 = 4. The decimal point doesn't move — the digits do (KS2 lesson, but useful to plant the idea).
Frequently asked questions
Why 'add a zero' — isn't that just a rule?
It's a consequence of the place-value system: 7 ones become 7 tens, written 70. The zero is a placeholder for ‘no ones’. Show this with Dienes blocks.
Doesn't ×10 mean the digits move?
Yes — ‘the digits shift left, the decimal point stays’ is the more correct phrasing, especially when decimals arrive in Year 4.
Tens facts up to where?
KS1 covers up to 12 × 10 = 120. KS2 extends to 10 × any number.
