This is a super cute and easy pumpkin/fall themed activity. All you need is:
*cut up green yarn (or string or whatever else you might have)
*orange circles (or pumpkin cutouts or stickers)
*a sheet of paper
Have your child create a "pumpkin patch" by gluing the "pumpkins" and the "vines" throughout the paper. You could even have various sized orange circles!
Super simple, frugal, and a fun way to teach that pumpkins grow on a vine (they don't just appear in a box at a grocery store!).
