Kids love slapping things. The goal is to get them to not slap each other. I'm sure you have seen some version of "Sight Word Slap" before, where you give the kids fly swatters, and they have to slap the word before their opponent does. I tried it and the kids were obsessed!
This is how we played...I placed several of our sight words on the table. Two kids got to hold a fly swatter, and the kids would go around the table taking turns reading any word they could see. The first person to slap the word got a point for their team! They were so excited to be reading, earning points, but most of all to slap with the swatters.
There was definitely DRAMA when they slapped the word at the same time... that called for a "re-read"....
I would love to have this at a center, but this is not something you can leave the kids alone doing....we can all see how that could turn real bad, real fast. :) But my heart was happy when the students were engaged, practicing their sight words!
