📐 Topic Summary
3D shapes, also known as solids, are objects that have three dimensions: length, width, and height. Unlike 2D shapes (like squares and circles that are flat), 3D shapes take up space. This worksheet helps you identify common 3D shapes in everyday objects, bridging the gap between abstract geometry and the world around you. Understanding these shapes builds a strong foundation for more advanced math concepts later on.
🧮 Part A: Vocabulary
