Fractions at the age of 3

This is the second time Cooper has brought one of these sheets home.  I had no idea they introduced preschoolers to fractions.  He loves telling me what each of them mean.

He is also practicing his name.  He got the first two letters in the box above.  We have been practicing spelling since the letters are on his wall above his bed.  He can get through the "e", but keeps forgetting the "r".
