I had made Alphabet Easter Eggs for Butterfly to practice her upper and lower case letters, then I saw this idea to use for Number practice. (I forget and can't seem to find now, which site I saw this from, remind me if it's yours.)
Numbered Easter Eggs with pom poms.
I included zero, to reinforce this number as well.
Fill the egg with the right amount of pom poms.
And of course, the zero egg was kept empty!
And here's some cute Spring worksheets I found at Kids Soup that Butterfly enjoyed doing.
