7. Mini white boards ready!

8. Simplify the following
3a + 2b + 2a - b

9. True or False
2n means the same as n + 2

10. Expand the bracket
2(a + 6)

11. True or False
3(b + 2) = 3b + 5

12. Expand and simplify
3(x + 2) + 2(2x + 4)

13. Can you expand…
(x + 2)(x + 4)

14. True or false
3a + 2a + 2b – b = 5a + b

15. Today’s Task
Now its time to answer the questions that you rated at the start of the lesson.
It is important that you start with the questions that you rated amber.

16. Plenary Can you spot my mistake? 3(2x + 5) = 5x + 8

17. Convince me that…
3(x + 4) is not the same as 3x + 7
7a – a does not equal 6.
