I found some of these at the store recently!
Have you seen them???
I bought them right away and we've been having so much fun with them in preschool! I made an ABC chart, we give the kids a pile of crackers and they match the cracker letters to the letters on the chart! For the kids that already know their letters, they can find the cracker letters to make their name or simple words! So fun!
p.s. If you would like a copy of the chart I made, just shoot me off an e-mail and I will attach it to an e-mail and send it back. I created it in Word.
