## Lesson details

### Key learning points

- A quadrilateral is a shape with four sides and four vertices.
- Interior angles in a quadrilateral are composed of two triangles.
- Interior angles in a quadrilateral are equal to 360 degrees.

### Common misconception

Pupils may not have fluency in properties of 2D shapes and may therefore not notice properties of angles within quadrilaterals such as trapeziums.

Pre-teaching or providing a scaffold containing shape names and properties will allow pupils to see the properties and support them in making connections.

### Keywords

Quadrilateral - A quadrilateral is a polygon with four straight sides and four vertices.

Point - A point is an exact location. It has no size, only position.

Sum - The sum is the result of adding two or more numbers.
