This video looks at how to identify the rule and continue a pattern involving decimals.

Complete the pattern: 4.2, \, 4.0, \, 3.8, \, ⬚, \, ⬚, \, ⬚ .

Worked Solution

Idea summary

To continue patterns with decimals, we look for how our numbers are changing. Then we can continue the pattern.

This video looks at some pattern concepts where we cross over whole number values, and places.

Consider the following pattern. 1.8, \, 1.5, \, 1.2, \, ⬚, \, ⬚, \, ⬚

a

What is the pattern?

A

Subtract 0.03

B

Subtract 3

C

Subtract 30

D

Subtract 0.3

Worked Solution

b

Complete the pattern.

Idea summary

When continuing a pattern, we need to make sure we remember the place value we are looking at, so we can regroup if necessary.
