What is a Dozen?
Empty egg carton; art supplies such as crayons, paint, stickers, or markers; 12 items such as crackers or toys that will fit in egg carton compartments
Help your preschooler learn what a dozen is and practice counting to 12. Let your child decorate an empty egg carton with crayons, markers, stickers, and/or paint. Then he can fill each compartment with any small item, such as marbles, small toy cars, crackers, or whatever he'd like, as he counts to 12. You can also use the egg carton to teach him about subtraction. If you take out 2 marbles, how many are left?
