If you haven't seen Teacher Tipster videos, go there directly after reading this. He has some awesome videos on teaching children place values, time, and this is where I got the idea for math power tower.
I purchased the dixie cups from Costco and on the bottom of each cup you write a math fact, I made addition and subtraction sets for my younger son and a multiplication set for my older son. Inside each cup is the answer. The idea is that the child reads the math fact and if he/she answers correctly they can build a tower with each cup. What kid doesn't love building!
I've now made sets for both of my son's homeroom teachers so that the teacher can incorporate it into their classroom learning environment. To store the cups I used tennis ball containers but you can also use a Pringles can. I picked up the labels for the cans from this blog, she offers a free download.
Of course these towers can also be made using sight words too! And while you make one for your kids, make a set for your child's classroom as well- the teacher will be thrilled!
P.S.- Pajamas are optional.
