I've kept busy this summer helping elementary students develop an understanding of math. One of their favorite activities is using Place Value Styrofoam Cups. I saw this idea on Pinterest and decided to give it a try.
We use the cups to:
understand place value
practice counting forward and backward
learn the names of large numbers
decompose numbers to expanded form
I've given cup sets to several teachers and they have reported very positive results. This prompted me to write directions for making them. The directions are a FREE download on my Teachers Pay Teachers store. Registration is required, but there is no cost to join.
