So, to make it just get some pattern block picture templates (I got mine from PreKinders). Then, write the sight words you want the kiddos to practice on each shape blank.
To play, pick a pattern board and grab a tub of pattern blocks. To cover a space, a child has to say the word on the space AND use it in a sentence correctly. If they can do those two things, they can cover the space. You can play it as a game, each child with their own board, and see you can fill the board first.
