I realize how important family is, and we often don't get to spend enough time with our little ones. The only homework I would like your child to do is snuggle up with you and read a book each night for at least 10 minutes. Point to the words while you are reading. Point to the pictures and have a discussion with your child about the book while creating life-long memories and a love for reading.
I may occasionally send other things home, but they are optional but beneficial.
