Check out the Day 1 Imagination Station Sciency-fun Gizmo. Includes step-by-step instructions for assembling the Off-Rail Rollers.
You’ll want one Off-Rail Roller per elementary kid.
Preschoolers use Off-Rail Rollers during Exploration Stations, so you’ll need an additional 10-pack for that station (preschoolers to do not this gizmo home).
