Flat vs. Solid Shape Sort (3D Shapes)
This sort activity is designed to ensure students truly grasp the concept of sorting by shape—not just by visual cues like color. Unlike activities where items may be color-coded, this sort challenges students to focus solely on identifying and categorizing flat (2D) shapes and solid (3D) shapes, fostering a deeper understanding of shape attributes and differences. Students practice distinguishing between shapes they can draw on paper and solids they can hold, helping build essential geometry v
