A lot of sight word activities. Sight Word Graphing - good idea, can adapt for more difficult words and get a newspaper article or a page from a book/story and have them go through and graph how many times the sight words occur from the article/story.
Sight word dice game- During this activity students can practice their sight words by rolling the dice and writing the sight word based on their roll. I like that I can accommodate this activity based on our learning and/or student need.
Big Book Station--these are sight word pointers and are great for finding sight words in books. The children choose a pointer and look for that word as they read. I printed the words on colored cardstock stars and taped them to straws.
