# Patterns with tenths and hundredths (add/sub)

Lesson

Let's bring together everything we've seen so far with patterns - whether working with decimals in the tenths place, decimals in the hundredths place, or fractions. Each time, we've seen that we need to:

1. Find the pattern - which will either be given, or which will need to be found by looking at the list of numbers.
2. Continue the pattern - using the pattern that you found.

Watch the video below to see some examples!

Now that you've seen how to work with patterns using decimals and fractions, have a go at some questions!

#### Worked Examples

##### Example 1
