Paper grocery bags; boxes (shoe boxes or other gift boxes work well)
These blocks are easy to make and great for one year olds who aren't quite able to skillfully maneuver heavy wooden blocks yet, and older kids will enjoy them, too. You can make 2 types: 1) To make large blocks, fill a paper grocery bag full with crumpled newspaper. Fold and tape the sides of the open end as if you were wrapping a present. Help your child decorate the blocks using markers, crayons, or stickers. 2) To make smaller blocks, use shoe boxes covered in colored construction paper or wrapping paper. Now let your child build (and knock over!) the blocks.
