I believe this site is free for teachers and Home-Learning Families for A YEAR.

Students can read these online books together with you or on their own. Lots of different categories of which to choose! Have fun….try to pause and locate words…frame them! Look away and spell them! If you have magnetic letters …try to “make/build the word”!...then “Mix and Fix”; play “What’s Missing?” or “Table Write!” the sight/popcorn word!
