Here is a little math activity I did with the kids that they actually LOVED.
I got a fishing pole and attach a clothes pin to the end of the line. Then I filled a baggie with various colored fish crackers. If you have a staircase that works really well. If not, you can always have them fish over the back of a couch.
I had them drop the line (and the clothes pin) over the staircase and then I attached the bag of fish crackers at the bottom of the stairs and gave the line a tug.
They loved reeling in their "fish"
I had them separate the fish into colors and put them in a little pile.
