## Step 3 | Add by making 10 • Represent and use number bonds and related subtraction facts within 20.
• Add and subtract 1-digit and 2-digit numbers to 20, including zero.
• Read, write and interpret mathematical statements involving addition (+), subtraction (–) and equals (=) signs.

## Maths Focus

• Children will add two single-digit numbers that total more than 10, by breaking one number into two parts to bridge the 10.
• Children will deepen their understanding and proficiency in adding two single-digit numbers by bridging 10.

## Step 4 | Not crossing 10 • Represent and use number bonds and related subtraction facts within 20.
• Add and subtract 1-digit and 2-digit numbers to 20, including zero.
