Just some of the ways we have been exploring with them:
Sort them by color
Sort them by shape
String them together
Use them to measure lengths
I placed some on my copier and made some pattern cards for the kids to follow too.
I covered them in clear contact paper so they would last a little longer.
These are a great deal. If you have a Dollar Tree near you, go grab some. Your kiddos will gain some great skills using them....counting, patterning, color recognition, fine motor, problem solving, creativity....for cheap, cheap!
