### Exploring Wild & Wonderful Number Patterns

EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.

### I'm Eight

Find a great variety of ways of asking questions which make 8.

### Sending Cards

This challenge asks you to investigate the total number of cards that would be sent if four children send one to all three others. How many would be sent if there were five children? Six?

# 1, 2, 3, 4, 5

## 1, 2, 3, 4, 5

Using the numbers $1, 2, 3, 4$ and $5$ once and only once, and the operations $\times$ and $\div$ once and only once, what is the smallest whole number you can make?

### Why do this problem?

This short problem could be used to start a lesson or fill a gap made by those who finish early. It will promote thinking about numbers and offers opportunities to practise multiplication and division.

### Key questions

What results can you find obeying these rules?
Why do you not get any divisions by $5$?
Does it help to multiply by $1$? If not, why not?
