Stage: 1 Challenge Level: 
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 $4$ 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?
Possible extension
Challenge children to make different repeating patterns using the tiles, or they could design their basic tile.Possible support
Learners could try the Turning Man problem first.Mixed triangles. Reflections. Visualising. Tangram. Rotations. Compound transformations. Working systematically. Practical Activity. Interactivities. Investigations.
