## Lesson details

### Key learning points

2. The addends are written in columns with the same value digits in the same column
3. The sum is recorded underneath the addends with the same value digits in the same column

### Common misconception

Pupils may not refer to the size of the numbers when manipulating the digit cards.

Encourage them to talk about the size of the numbers and whether the digit cards represent ones, tens or hundreds.

### Keywords

• Sum - The sum is the the total when numbers are added together.

• Column addition - Column addition is a way of adding numbers by writing a number below another.

Pupils would benefit from having the number cards 0-5 to help them solve the problems in the lesson.
