Each year during our study of liquid measurement I encourage parents to obtain plastic measuring cups, spoons, and containers for their children to practice measuring. The children respond to this homework because we call it 'Math Bath.' In their assignment notebooks each night we write 'take a bath' in the math block. The children are to take their plastic containers to the bathtub and practice measuring (ex: How many teaspoons are in a cup?) The children love to surprise their parents with the silly assignment and they really do practice their measuring skills!
