This set of puzzles is a great resource to reinforce matching upper and lower case letters. The puzzles have a colorful superhero theme to appeal to students. The letters are written using the D'Nealian font.
I have included an answer key so students can self-check their work. I suggest laminating the puzzle pieces and answer key to ensure they last for many years.
