This is a set of 9 very simple BINGO cards for preschoolers. I have TONS of letter cards around my classroom (as I assume ALL teachers do) so I didn't add cards. Just take some letter flash cards, letter tiles or even letter magnets, pull them out of a basket and call out the letter. The kids will put a marker on their game board over the letters until someone has 4 in a row. Remind the kids to look for BOTH lowercase and uppercase letters.
