Pat - Tyylee, do they stay without turning over. I hate letters that turn over. The letters cost enough, companies should put enough magnets on them. Yes, they slide easily but stay in place better on the board. We send the CUS in an envelope to be glued in a book that we made.
Students then illustrate the page.
I send mine home every night but at this point in the program they aren't doing them every night as they should. On that day we use the homework book for Familiar Reading and the student gets a prize for completing the book. I have started including some word cards in the homework for a couple of slow to accelerate children. They just weren't acquiring sight vocab. It seems to be helping.
