Your little engineers can build their very own playgrounds as they build early STEM skills. Plan, design, and then build a seesaw, a swing set, a slide and so much more! Use the activity cards to direct the play, or simply allow kids to explore open-ended building possibilities. The added art component turns STEM into STEAM to round out the learning. The included guide comes with reproducible worksheets. Slide measures 6”L.
