A PDF PowerPoint based on a selection of Maths SATs, tricky, reasoning questions with answers. I have also included a 'Convince Me' question at the beginning, whereby children can work independently or as a group to solve this. At the end are the rules for playing the game Pentamin, for which I have included the link for the website where you can print the game board. It was a lesson that I used in the run-up to SATs, however, could be used as a collaborative lesson once a unit has been complete
