# Star Find

Can you see which tile is the odd one out in this design? Using the
basic tile, can you make a repeating pattern to decorate our wall?

## Problem

Here is a grid made up of $9$ squares. All of them are the same except for one. Can you find the odd one out?

The basic tile from the design above looks like this:

In the star design, the tile has been turned around, or
**rotated** , into different positions.

Below is a wall of $16$ blank tiles. Using the basic tile, can you
make a **repeating pattern** to decorate our wall? Try
making more designs by rotating the tile and using it in more than
one position.

## Student Solutions

Debbie who is 7 and goes to Applegrove Primary School tells us that the odd one out is the middle square because it has two of the designs on it.

## Teachers' Resources

### Why do this problem?

This problem gives learners a chance to talk about similarities and differences, and also rotations and, in particular, quarter turns. These sheets may be useful to give to pairs or individuals:this sheet has $16$ copes of the basic tile and this sheet has a $4$ by $4$ grid which is the same size as the tiles.### Key questions

What can you tell me about this pattern?

What is the same about these two tiles?

What is different about these two tiles?

How can we make this tile look the same as that one?

How will you arrange the tiles to make your own pattern?
