This center couldn't be easier to set up. Just spread sight word circles on the floor and toss a bean bag. Your students will have so much fun while they learn their sight words. There are 38 Benchmark sight words along with 22 more words that we use in our district. There are six lists with 10 words in each. The lists are color coded in rainbow colors. The easiest is the red List A and the hardest is the purple List F.
