Staggered rocks are better than stacked rocks...check!
Knowing where to put rocks...check!
First graders investigated the rocks they'll be using to build their walls, thinking about each rock's unique properties. Some rocks were pointy, making them good to sneak between jagged areas. Other rocks were small and couldn't support a lot of weight at the base of the bottom, leaving a first grader to acknowledge their future use at the top of a wall. Great thinking first graders!
