Identify faces of three-dimensional shapes

Learning Objectives Point to a face on a 3D shape. Define a 'face' as a flat surface. Count the number of faces on a cube. Count the number of faces on a rectangular prism. Identify that a sphere has zero flat faces. Match a 2D shape (like a square) to the face of a 3D shape (like a cube). Have you ever held a building block? 🧱 Let's look at its flat parts! Today, we will learn about the flat parts of 3D shapes. These are called faces. Knowing about faces helps us build amazing things! Real-World Applications Building with blocks Stacking cereal boxes at the store Wrapping a gift in a box 🎁 Looking at the sides of a dice 🎲

TermDefinitionExample 3D ShapeA solid shape that you can hold in your hands.A toy block, a ball, or a party hat. 🥳 FaceA flat surface on a 3D shape.The side of a dice with the dots on it. Flat SurfaceA part of a shape that is not bumpy or round.The top of a table or the cover of a book. 📖 Curved SurfaceA part of a shape that is round, like a ball.The outside of an orange 🍊 or a basketball. CubeA special 3D shape with 6 flat, square faces.A sugar cube or a toy block. Rectangular PrismA 3D shape with 6 flat, rectangle faces.A cereal box or a juice box. 🧃 SphereA perfectly round 3D shape with no flat faces.A bouncy ball or a marble. ⚽

Cube Face Rule A cube has 6 flat faces. Use this to remember how many sides to count on a block or a dice. Rectangular Prism Face Rule A rectangular prism has 6 flat faces. Use this when you look at a box, like a tissue box or a book. Sphere Face Rule A sphere has 0 flat faces. Remember that a ball is all curved, so it has no flat faces to count.
