📚 Topic Summary
Cutting, tearing, and bending are all ways we can change the shape of materials. When you cut something, you use a sharp object like scissors to separate it into two or more pieces. Tearing is when you pull something apart using force, like ripping a piece of paper. Bending involves changing the shape of an object without breaking it, like bending a straw. Let's practice these concepts! 🤔
