Little engineers can build their very own playgrounds while developing 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 let kids 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 in long. Size: 35.3 x 25.7 x 7.9 cm. Ages 5+.
