You will all be familiar with the game ‘dominoes’ but what is a triomino? A tetromino? A pentomino? How many arrangements of each can be made? In the second academic workshop of the term, Year 5 explored polyominoes and all of the different possibilities. Once again, the children demonstrated excellent collaborative skills and resilience. As a final challenge, the children had to try to fit all of the pentominoes into a rectangle. This really put their spatial reasoning to the test!
