Quick quiz on comparing shape sizes for 3rd graders.

📚 Quick Study Guide

• 📏 Understanding Size: Size refers to how much space a shape takes up. We can compare sizes by looking at shapes and deciding which is bigger or smaller.
• 👁️ Visual Comparison: Sometimes, you can tell which shape is bigger just by looking! If one shape clearly covers more area, it's larger.
• 🧩 Overlapping: Imagine placing one shape on top of another. If the first shape completely covers the second shape, then the first shape is bigger.
• 📐 Using Units: We can also measure the size of shapes using units like squares. Count how many squares each shape covers to compare their sizes.
