Just in case you haven't noticed, I have been adding fun things to do with the kiddos this summer. These have been SUPER SIMPLE activities that require little money. We recently set up a marble run out of the swimming pool noodles. You cut the noodle in half, there is a crease in the middle- perfect for a marble run! Set up a track using several noodles, and masking or painters tape. Then get your marbles lined up for some fun!
