Encourage your kids to read all summer with an add-a-bead bookmark.
At the beginning of the summer, buy beads that your child will find enticing: letters that spell out his name, for example, or some shaped like bugs or animals. Tie one plain bead to the end of a yarn lace, and have him use the lace as a bookmark. Each time he finishes a book (or a chapter, for lengthier tomes) he gets to pick out a bead and add it to his bookmark.
A yarn lace with tips makes for easy stringing
