Growing and Shrinking Patterns Study Sheet

Growing and Shrinking Patterns Study Sheet

A growing pattern happens when something is added each time. You can have a growing pattern with pictures, objects, shapes, and even numbers. Look at the following number pattern. How does it grow? 

1, 4, 7, 10...

Think of addition with growing patterns.
1+1=2
2+1=3
3+1=4

----------------------------------------------------------------------------------

A shrinking pattern happens when something is taken away each time.

12-3=9
9-3=6
6-3=3

3-3=0

An architect is designing a neighbourhood of houses.  Describe the architects design pattern.

Sample answer:

Number of Houses	Number of Shapes
1	2
2	4
3	6
4	8
5	10

The house pattern is an increasing pattern.  I would need 10 shapes to build the 5^th house.

I used a t-chart to help me organize the data (I will be able to fill in a blank t-chart). 

The number of shapes is growing by 2 each time. 

0+2=2

2+2=4

4+2=6

6+2=8

8+2=10
