## Lesson details

### Key learning points

1. The negative or minus sign in front of a number shows that it is a negative value.

### Common misconception

Pupils do not write negative numbers beginning with the negative symbol e.g. writing 3- and not -3.

Take time to model the writing of a negative number. "I know it is negative so I begin with the negative symbol."

### Keywords

• Numeral - A symbol or name that stands for a number

• Negative number - A number less than zero.

Give pupils frequent quickfire counting opportunities at different points in the day - for example, when lining up. This can be with a resource, such as a counting stick, or without. Count backwards and forwards across zero, initially in ones.
