Base Ten rods-not PinMoors but they work.
It took forever to upload this one pic of the Base ten rods I have. Search the internet for Base Ten rods (Math manipulatives). I found many places that sell them. BE SURE to get the FOAM ones that are green and not the wooden or plastic ones.
They were developed by a man named George Cuisanaire. ( I think). The orignal rods we used to get were called Cuisanaire but now they are just called Base ten rods (made in Taiwan). I found them from $3.99 to way over $20.00. If you like them wide get the 100 rod size and cut them any size you want. Like I said, I use the Base ten and cut them in thirds, to help protect my fingers a bit better. I put the pins in long ways.
I hope you try them and I hope they work for you.
