While teaching word families, I use these mats (printed on colored paper and laminated) in multiple ways: rolling the dice to spell "-ot" words, shaping letters out of play-dough to spell "-ot" words, and dry erase writing "-ot" words!
The dice attached can be printed on colored paper to match, or white. Each letter or letter combination has matching picture clue and spells a real "-ot" word.
Note: My kids were fascinated with making dice out of paper after this activity! :)
