### Domino Square

Use the 'double-3 down' dominoes to make a square so that each side has eight dots.

### The Puzzling Sweet Shop

There were chews for 2p, mini eggs for 3p, Chocko bars for 5p and lollypops for 7p in the sweet shop. What could each of the children buy with their money?

### Sandwiches

Arrange the digits 1, 1, 2, 2, 3 and 3 so that between the two 1's there is one digit, between the two 2's there are two digits, and between the two 3's there are three digits.

# Plenty of Pens

## Plenty of Pens

Amy went into her local stationery shop. Her mum had given her £$2.50$ to spend.

Amy liked the look of some luminous pens and fancy pencils.

She bought four times as many pens as pencils and was given $40$p change.

How many of each did she buy?

### Why do this problem?

This problem can be approached in several different ways (by randomly trying numbers, working in a systematic way to try numbers, making a table) and could be a nice way of introducing algebra.

### Key questions

What do we know?
What could we try first?
How many pencils might she have bought? How many pens would that mean she'd bought?
What could we try next?

### Possible extension

Learners could try Buckets of Thinking which involves similar mathematics.

### Possible support

Using real pencils and pens may help children keep track of what they have tried.
