Lesson 1: Introduction to Shapes
Objective: Students will be able to identify shapes in 3D objects
Materials Needed:
- Various 3D objects (cubes, pyramids, spheres, cylinders)
- Magnets (optional)
Lesson Plan:
1. Begin the lesson by introducing the concept of 3D objects. Explain that 3D objects are real-life items that have more than two dimensions. Give examples of 3D objects that can be found in the classroom (e.g. ruler, eraser, desk, books, pencil cases etc.)
2. Introduce the 3D objects that students will be working with. These will likely include cubes, pyramids, spheres, and cylinders. Ask students to describe the shapes of these objects, and explain that these are the same shapes used in everyday objects. Students can hold the objects in their hands, explore them, and even use magnets to make them “float” in the air if magnets are available.
3. Ask the students to identify which objects have the same shape. For example, ask them to look at a cube and a pyramid and determine which shape is the same. Ask other questions like, “Which shape is different from the others?”
4. Call on students to explain their answers, and then explain why the shapes 3D objects have these shapes. Explain that the shapes are used to create different objects. For example, cubes are often used to build buildings, pyramids can be found in certain types of ancient architecture, and spheres can be used as balls in sports.
5. Conclude the lesson by having students draw 3D objects on a piece of paper. Ask them to name the shapes they drew, and explain why the shapes are useful.
Assessment: Ask students questions throughout the lesson and use their drawings as a form of assessment.
