As part of our exploration of Natural Maths through the Multiplication Explorers course (described in my post here), we made multiplication manipulatives out of pieces of board, nails and wool. It was a maths lesson in itself for the boys to use a protractor to divide a circle into 10. They then enjoyed banging the nails into the wood, and then winding the wool around in patterns to show the multiplication tables. For me, it was such a different way to see these number patters, and particularly helpful to my second son, who isn't a great fan of numbers, but is a visual learner.
