1. Starter Question 1. Write the next two numbers in the sequence: 14, 28, 42, 2. Write the first three square numbers 3. Write 20m in cm 4. 36, 50add 14 1, 4, 9 20 x 100 = 2000cm 30 ÷ 10 = 3x 7 = 21

2. Simple Linear Patterns A pattern is made using matchsticks: 1 triangle 3 matches 2 triangles 6 matches 3 triangles 9 matches Number of Triangles (T) Number of matches (M) 12345 36912 15

3. Simple Linear Patterns Number of Triangles (T) Number of matches (M) 12345 36912 15 + 3 For every new triangle => the number of matchsticks rises by 3

4. Simple Linear Patterns Number of Triangles (T) Number of matches (M) 12345 36912 15 + 3 In words: no. of matches = 3 x no. triangles In symbols: M = 3 x T

5. Simple Linear Patterns M = 3 x T Q) If there are 20 triangles how many matches do I need? Know T=20 M = 3 x T M = 3 x 20 M = 60

6. Simple Linear Patterns Number of Spiders (S) Number of legs (L) 12345 8162432 40 1 spider 8 legs 2 spiders 16 legs 3 spiders 24 legs

7. Simple Linear Patterns Number of Spiders (S) Number of legs (L) 12345 8162432 40 + 8 In words: no. of legs = 8 x no. of spiders In symbols: L = 8 x S

8. Simple Linear Patterns L = 8 x S Q) If there are 20 spiders how many legs are there? Know S=20 L = 8 x S M = 8 x 20 M = 160
