Pupils get given 3x3 grids and must shade any number of squares so the grid has reflection symmetry. They need to try and find the total number of ways that this is possible (they hopefully will not need as many grids are as on the worksheet). It is important that they try to be logical in the way they do it! If you like this resource then please check out my other stuff on here!
