# Visualising and Explaining at KS1

Young children are often good at imagining - in these tasks we ask them to use their imaginations in a mathematical way.

### How Many Pieces?

##### Stage: 1 Challenge Level:

How many loops of string have been used to make these patterns?

### Holes

##### Stage: 1 and 2 Challenge Level:

I've made some cubes and some cubes with holes in. This challenge invites you to explore the difference in the number of small cubes I've used. Can you see any patterns?

### Poly Plug Pattern

### So It's 28

##### Stage: 1 Challenge Level:

Here is your chance to investigate the number 28 using shapes, cubes ... in fact anything at all.

These caterpillars have 16 parts. What different shapes do they make if each part lies in the small squares of a 4 by 4 square?
