Tens Rods (as I call them) and Ones Cubes can be a hot commodity. I know how we beg and borrow for more of these tools. One way to help the situation is to make them yourself. I know…who has the time for something like this…but let me tell you, this is one of the easiest DIY projects I will ever post. I would still have your district buy the ‘real’ ones but these are good for extra groups and just to have some extra on hand.
(whew, that was a lot 🙂
1) Tens Rods and Ones Cubes measure about 1 cm in width; so I just take a ruler and mark small nicks 1 cm apart on the sponge
2) Then cut and that’s it.
It doesn’t come out perfect, but the kids still understand that 10 ones cubes equal 1 ten rod. It gives them a 3D tool that is cheap, cheap, cheap!
