Quadrominoes Solution

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

How many different shapes can you make by joining together four square tiles edge to edge?

Solution:

There are seven different shapes you can make by joining together four square tiles edge to edge.

Any other shapes can be turned around to match one of these. 

If you are allowed to flip the shapes over then there are two pairs of shapes which are the same. There are then only five different shapes.
