Hook

Warm Up:

Complete the table below with a partner.

Answer these questions on whiteboards to remind yourself of what you learnt last week.

(Use blocks or counters to help!)

n + 5 = 12

n - 3 = 7

n × 4 = 20

18 ÷ n = 6

n + 8 = 15

3 × n = 9

Create 3 slips of paper with an algebra question on it. Stick to n + ? = 10

Go around the room and guessing what people have for n and if you get it correct take their piece of paper.

The pupil with the most pieces wins!
