The kiddos playing & learning with Grimm’s wooden sets. The rainbow is a favorite. I’m always intrigued at what Maggie & Lily come up with when they build something with it. Maggie’s last creation was a maze to fit the wooden balls through. Lily turned an arc upside down and made it a seesaw. I love working with these at the end of the day. These are one of the few materials the kids play with together beautifully. With no fuss. None.
