Montessori Math

Lately Hunter's biggest questions/concerns have been how much is one hundred and how much is one thousand. I think these questions started after we read the Usborne book "How big is a Million?" (shamelessly spamming myself! It really is a neat book, hardback and has a HUGE poster in the back with a.. well, I don't want to give away the ending but lets just say it has a million of something!)

So since most EVERYTHING is packed up I've been racking my brain trying to figure out how to illustrate 100 and 1000 for him. One of the ladies on my diapering message board is into Montessori teaching and I had seen her post pics of her homemade montessori materials before so I asked her about it. I ended up making 10's bars out of pipe cleaners and pony beads, total cost $4.

So I put 10 beads on a half pipe cleaner and twisted the ends back into the beads to keep them from falling off. I made 10 of these. Then with Hunter we counted out 10 individual beads. Then I showed him how we could replace 10 of those beads with a 10 bar, and then did 11-20, 21-30, etc.. you get the picture. When we got to 100 he got a huge grin on his face and it was like a light bulb went off. He could SEE 100 and actually understand how we got there! AMAZING!
