# Algebra: Formulae

Formulae lesson plan

## KS3 Bitesize

### Objectives

• Pupils recognise the use of algebra in solving shape and space problems

### National Curriculum

• AT2 level 5, AT3 level 4

### Resources

• Worksheet
• Pencils, pens
• Further pre-prepared questions

### Teaching activities

#### Mental Starter

• Quick fire questions on simplifying.

"If I have 2x over here and another 3x over here how many x's do I have?"

"What is 3 + 4?"

"What is 5-3?"

Etc.

#### Activity

1. Give the work sheets out
2. Go through the first part of the worksheet
3. It may be appropriate to put some additional questions on the board to bridge the gap. Maybe rectangles and then triangles
4. Once the pupils have mastered that they can move on to the exercise at the bottom

#### Extension

• Solving equations would be a natural progression and extension to this topic, introducing the pupils to more complicated questions

#### Plenary

• Quick fire questions on simplifying expressions

#### Homework

• A pre-prepared sheet of basic expression to simplify
