We talk a lot about using manipulatives in the classroom and I stumbled across these prime number manipulatives that a teacher came up with. He used Scrabble tiles and wrote on the back of them. He admitted to runing about 5 Scrabble games in the process, but you can always use them in the game again. He used these tiles to show up on a document camera and the students used paper ones that looked like them. I thought it was a cool way to show prime factorizations of numbers then using them to find the GCF and LCM of two numbers. It just shows us that if you are creative, you can think of your own cheap manipulatives to use in your classroom.
