Year 7 Maths Lesson 7: Substitution (recap)

Learning Objectives:
Substitution (Recap)

Introduction:
What do pronumerals represent?
Please note in your books:
If a = 10, what does 3a = ?

3a
= 3 x a
= 3 x 10

Convention:
We write 5 lots of x as:
5x

We write 3 x (x + 1) as:
3(x + 1)

4ab is the way we write 4 x a x b

If a = 2 and b = 3, what does 4ab = ?

4ab
= 4 x a x b
= 4 x 2 x 3
= 8 x 3
= 24

If T = 4a - 2, what does T = ?

Year 8 Maths Lesson 7: Addition and Subtraction in Algebra

Learning Objectives:
Substitution involving powers

Resources:
Heinemann 8
WS C4-9 - Mixed simplification
HW Worksheet

Extension Work:

Supplementary Work:

Timing:
Intro (5 min)
Reminder of simplifying:
7f + 8fg - 4f - 6fg
= 7f - 4f + 8fg - 6fg
= 3f + 2fg
5x + 2y - 3xy + 2x
= 5x + 2x + 2y - 3xy
= 7x + 2y - 3xy
1) Identify the pronumeral part of each term
2) simplify like terms
