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. 7
of 3010
36, 50 add 14
1, 4, 9
20 x 100 = 2000cm
30 ÷ 10 = 3
x 7 = 21
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)
1 2 3 4 5
3 6 9 12 15
Simple Linear Patterns
Number of Triangles (T)
Number of matches (M)
1 2 3 4 5
3 6 9 12 15
+ 3 + 3 + 3 + 3
For every new triangle =>
the number of matchsticks rises by 3
Simple Linear Patterns
Number of Triangles (T)
Number of matches (M)
1 2 3 4 5
3 6 9 12 15
+ 3 + 3 + 3 + 3In words:
no. of matches = 3 x no. triangles
In symbols:
M = 3 x T
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
Simple Linear Patterns
Number of Spiders (S)
Number of legs (L)
1 2 3 4 5
8 16 24 32 40
1 spider
8 legs
2 spiders
16 legs
3 spiders
24 legs
Simple Linear Patterns
Number of Spiders (S)
Number of legs (L)
1 2 3 4 5
8 16 24 32 40
+ 8 + 8 + 8 + 8
In words:
no. of legs = 8 x no. of spiders
In symbols:
L = 8 x S
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
