Here is a great and fun idea for kids. Turn a spot of your yard into a giant version of the classic paper-and-pencil game tic-tac-toe. Stone pavers laid into the lawn in a checkered pattern create the playing board. Kids will paint rocks into playing pieces. Enjoy!

What you need:

• 5 or 9 square stone pavers
• Trowel or shovel
• Paint
• 10 smooth, clean stones
