Write an upper case letter on one half with a permanent marker and the lower case letter on the other half.
Write onsets (consonants or blends) on one half and rimes (word endings) on the other half. Children twist around and read words. You could also ask children to write the words.
Practice making and reading two letter words by writing a letter on each half.
Write numerals or number words on the eggs. Children fill with the appropriate amount of beans or pennies.
Make compound words with eggs.
Let children draw pictures of all the animals that come from eggs.
Write a poem about spring on a small sheet of paper. Fold it up and put it in the egg.
Practice addition and subtraction with eggs.
Write words on the eggs. Write the same word on a 1 ½” x 3” sheet of paper and cut between the letters to make a puzzle. Place puzzle pieces in the egg. Children shake and then open and put the pieces together to make the word.
Hint! I have tried both Sharpies and permanent markers and they rub off. I would suggest just putting clear tape on top of the marker.
