Add a gravel panel to the truck pit for increased learning and fun in your outdoor classroom. The Adventurous Child’s Gravel Panel Add-On provides three different ways for gravel to fill the trucks and containers below. Pouring gravel through the gravel panel allows children to observe and demonstrate directional words—in, out, on, off, here, there, beside, next to and between. (These prepositions will surely lead to a wonderful conversation about keeping the gravel in the pit!)
