### Lesson Plan: Ball and Box Shapes
**Grade:** Primary 2
**Subject:** Mathematics
**Duration:** 60 minutes
**Topic:** Ball and Box Shapes
---
#### Objectives:
1. **Knowledge:** Students will be able to identify ball (sphere) and box (cuboid) shapes.
2. **Skills:** Students will compare and contrast the properties of spheres and cuboids.
3. **Attitude:** Students will appreciate the presence of shapes in everyday surroundings.
---
#### Materials Needed:
- Real-life objects resembling balls (e.g., tennis ball, soccer ball, basketball)
- Real-life objects resembling boxes (e.g., cereal box, rectangular tissue box)
- Chart paper
- Markers or crayons
- Template of a sphere and cuboid to color and cut out
- Building blocks or modeling clay
---
#### Lesson Steps:
1. **Introduction (10 minutes):**
- **Welcome Activity:** Begin with a quick discussion about shapes they already know. Show images of basic shapes like circles, squares, and rectangles.
- **Introduce the Topic:** Explain that today we'll learn about ball shapes (spheres) and box shapes (cuboids). Show a real soccer ball and a cereal box to set the context.
2. **Lesson Development (30 minutes):**
- **Identifying Properties (15 minutes):**
- **Ball Shape (Sphere):** Show various ball-like objects. Discuss how they are round, can roll, and have no edges or vertices.
- **Box Shape (Cuboid):** Show various box-like objects. Discuss how they have flat faces, edges, and vertices.
- **Comparison:** Use a chart to compare the properties. For example, write on a board:
- Sphere: round, rolls, no edges
- Cuboid: flat faces, edges, vertices
- **Interactive Activity (15 minutes):**
- **Building Models:** Give students building blocks or modeling clay and ask them to create their own sphere and cuboid. Walk around and assist students, encouraging them to discuss the shapes they’re creating.
- **Cut and Color Activity:** Provide templates of a sphere and cuboid. Ask students to color and cut these out. Discuss the features as they work.
3. **Conclusion (10 minutes):**
- **Class Discussion:** Bring the group together and ask students to share what they made and observed about spheres and cuboids.
- **Everyday Connections:** Ask students to name other items in the classroom or at home that resemble these shapes.
4. **Assessment (10 minutes):**
- **Worksheet:** Provide a worksheet with pictures of various objects. Ask students to identify whether each object is more like a ball or a box and color accordingly.
- **Oral Questions:**
- Can you name something at home that looks like a sphere?
- What shape is a dice (if it’s a cuboid)?
- Which shape can roll?
---
#### Differentiation:
- **For advanced learners:** Challenge them to find other examples of 3D shapes like cones and cylinders and discuss their properties.
- **For struggling students:** Provide more guided practice and simplify the task, such as using just one sphere and one cuboid for identification and comparison.
---
#### Homework:
- **Shape Hunt:** Ask students to find three items at home that are spheres and three that are cuboids. Draw or bring a picture of these items to share in the next class.
---
#### Reflection:
After the lesson, reflect on what went well and what could be improved. Assess students’ engagement and understanding based on their participation in activities and accuracy in the worksheet. Adjust future lessons on 3D shapes based on observations and feedback.

This lesson aims to introduce primary 2 students to the fundamental 3D shapes of spheres (balls) and cuboids (boxes) through engaging, hands-on activities that solidify their understanding and appreciation of geometric shapes in their environment.
