"O" is for Octopus. Matching letters with pictures can help your preschooler or kindergartner learn letters and beginning sounds. With the Alphabet Match flash cards, each card shows a letter and colorful picture on one side while the reverse side repeats the letter with the word for that picture. Alphabet Match Flash Cards also show your child the difference between uppercase and lowercase letters. For every "o" ostrich card, there is an "O" Octopus card. Imagine all the fun in matching all the letters in the alphabet with everyday things like Apples to Zippers, and not-so-everyday things like Alligators to Zebras.
