Grade 3 Mathematics Lesson Plan: Space and Shape – Position, Orientation, and Views
Materials Needed:
– Geometric shape cut-outs (e.g., squares, triangles, circles)
– Grid paper
– Markers and crayons
– Ruler
– Projector or smartboard for visual demonstration
– Worksheets with position and orientation exercises
– 3D shape models (e.g., cubes, cylinders)
– Tablets/laptops (optional, for online activities)
Learning Objectives:
By the end of the lesson, learners will be able to:
1. Identify and describe the position of shapes using terms such as ‘above’, ‘below’, ‘next to’, ‘in front of’, and ‘behind’.
2. Understand and demonstrate the concept of orientation using 2D shapes.
3. Recognize and describe views of 3D objects from different angles.
Vocabulary:
1. Position – The location of an object (e.g., ‘above’, ‘below’).
2. Orientation – The way an object is turned or facing.
3. View – How an object looks from a particular angle.
4. 3D Shapes – Objects that have three dimensions (e.g., length, width, height).
5. 2D Shapes – Flat shapes that have only two dimensions (e.g., length and width).
Previous Learning:
Students have previously learned about basic shapes (2D), including circles, squares, and triangles, and have been introduced to the concept of flat versus solid shapes.
Anticipated Challenges and Solutions:
– Challenge: Students may struggle to understand the concept of orientation.
– Solution: Use hands-on activities with shape cut-outs allowing students to physically manipulate and position the shapes.
- Challenge: Some learners may find it hard to visualise 3D shapes from different views.
- Solution: Provide physical models and use technology tools (like a projector) that display 3D shapes from different angles.
Lesson Structure:
Beginning Activities (4 minutes):
– Briefly introduce the lesson topic, highlighting the importance of understanding position, orientation, and views in mathematics and real-life contexts.
– Engage students with a quick 2-minute discussion: Ask them to describe the position of a book on their desk (e.g., “Is it above or below the pencil?”).
Middle Activities (32 minutes):
1. Direct Instruction (10 minutes):
– Use the smartboard to demonstrate different positions of geometric shapes. Show visuals representing ‘above’, ‘below’, ‘next to’, etc.
– Introduce the concept of orientation with the help of shape cut-outs. Rotate shapes and ask students to describe their orientation.
- Guided Practice (12 minutes):
- Hand out grids and shape cut-outs. Ask students to place the shapes in designated positions (e.g., “Place the square below the triangle”).
- Circulate the classroom to provide support and feedback.
- Independent Practice (10 minutes):
- Distribute worksheets that require learners to answer questions about the position and orientation of shapes, as well as sketching views of a 3D shape from two different angles.
End Activities (4 minutes):
– Review the key concepts by conducting a 2-minute Q&A session where students can share what they learned about position and orientation.
– Issue exit tickets where students draw a shape and write its position and one orientation description, allowing for quick assessment of understanding.
Assessment and Checks for Understanding:
- Observation during guided and independent practice.
- Review of completed worksheets and exit tickets for comprehension of key concepts.
Differentiation Strategies for Diverse Learners:
- For Advanced Learners: Challenge them to create their own real-world scenarios using positions and orientations to explain to the class.
- For Struggling Learners: Pair them with stronger peers during the guided practice for additional support. Provide simpler shapes and clearer instructions.
Teaching Notes:
This lesson supports learners in developing spatial awareness, which is crucial for understanding geometry in further schooling. Utilising both 2D and 3D objects provides varied visual stimuli and kinesthetic learning opportunities. Ensure that all materials can be easily handled by students with physical disabilities, and consider using digital tools for learners who benefit from visual aids.
