I can solve problems involving missing coordinates

## Lesson details

### Key learning points

- Coordinate grids are not always presented with grid lines, and the axes are not always fully-labelled.
- When this is the case, it is essential to consider the known coordinates to work out missing coordinates.
- Missing coordinates sometimes appear on the same horizontal or vertical line as known coordinates, so they are the same.
- Sometimes we need to use known vertices to calculate unknown side lengths when working out missing coordinates.

### Common misconception

Pupils need to have proficiency in bridging across zero with negative numbers, in the range of −10 to 10. Grid lines that might help to support such calculations are not given in this lesson.

Pupils not secure will need a resource within the lesson to support their calculations, such as a number line going from −10 to 10.

### Keywords

Congruent - If two shapes are the same shape and size as each other, they are congruent.

Vertex / vertices - A vertex is where two or more line segments meet. The plural is vertices.
