Make a leaf collage, go on a scavenger hunt. Play I Spy on a walk, make a wacky relay race with obstacles in the backyard using household items. Paint leaves and stamp them onto newsprint. Make a rock garden, make scare crows using old clothes, use side walk chalk, blow bubbles.
Have fun = ) Having a special tote that you keep special puzzles and craft and hobby projects in for rainy days keeps them special.
Lots of luck
