Because I haven't posted a freebie in a while, here is something I hope you can use in any grade level.
You can add a magnet to the back or leave them as is. Some ideas I use them for are:
1. any type of word works: spelling names, CVC words, spelling words, sight words
2. ABC Order
3. Letter Sound Correspondence
4. Capital Letter Lowercase Letter Match up
What are some other ways that you would use these in your classroom?
