When Easter rolled around I gathered up plenty of plastic Easter eggs to use in a literacy center for my preschool class.
I separated the eggs (cut the hinges) and wrote a capital 'A' on one end and a lower case 'a' on the other end. Then repeated this with all the letters of the alphabet and put the 52 pieces in our science table with Easter grass for the students to dig through and find matches.
Not only did they have to match the upper/lower case letters but the colors of the eggs as well.
This activity could be modified to include matching numbers/dots, compound words, contractions, etc.
The ideas are limitless and the supplies are surprisingly cheap, especially if you buy the eggs and grass after the season.
