I created this center for my students to practice their high frequency words. This download includes all the high frequency words for Grade1- Reading Street Common Core Edition. Yes it also includes the Review unit!
You will need slider boxes for each group member. I use paper letter tiles to build the words. You could easily laminate letter cards, use small magnetic letters, or even old scrabble game tile pieces. Simply print, laminate, and cut slider cards and your center is ready to go.
