Grade 3 Lesson Plan: Exploring Area with Non-Standard Units

Objective: By the end of the week, students will be able to find areas of regular and irregular flat surfaces using non-standard units/regions, such as leaves, grids, or circles.

Materials Needed:

·         Leaves

·         Grid paper

·         Circular objects (e.g., lids, coins)

·         Rulers

·         Markers

·         Chart paper

·         Colored pencils

·         Scissors

·         Glue

·         Projector

·         Teacher’s Blogsite

Session 1: Introduction to Area (60 minutes)

Objective: Introduce the concept of area and non-standard units to measure it.

1.      Warm-up (10 minutes):

·         Begin with a brief discussion on the concept of area. Ask students if they know what area means and if they have any ideas about how to measure it.

2.      Introduction to Non-Standard Units (20 minutes):

·         Show students different non-standard units such as leaves, circular objects, and grids.

·         Discuss how these units can be used to measure area and why they might be useful.

3.      Activity: Leaf Exploration (30 minutes):

·         Divide students into small groups.

·         Provide each group with a collection of leaves.

·         Ask students to estimate and then measure the area of each leaf using the leaves themselves as units.

·         Encourage them to record their findings and observations.

Session 2: Exploring Grids (60 minutes)

Objective: Practice finding areas using grid paper.

1.      Review (10 minutes):

·         Recap the concept of area and non-standard units briefly.

2.      Introduction to Grids (15 minutes):

·         Explain how grids can be used to measure area.

·         Demonstrate how to count the squares within a grid to find the area.

3.      Activity: Grid Exploration (35 minutes):

·         Distribute grid paper and markers to each student.

·         Provide a variety of shapes for students to trace onto the grid paper.

·         Ask students to find the area of each shape by counting the squares within it.

·         Encourage them to compare their results with their peers.

Session 3: Measuring with Circles (60 minutes)

Objective: Practice finding areas using circular objects.

1.      Review (10 minutes):

·         Briefly review the concept of area and the use of non-standard units.

2.      Introduction to Circles (15 minutes):

·         Show students how circular objects can be used to measure area.

·         Demonstrate how to trace around the object and count the number of times it fits into the shape.

3.      Activity: Circular Measurement (35 minutes):

·         Provide students with circular objects of various sizes.

·         Instruct them to trace around the objects onto paper.

·         Have students count the number of times each object fits into the shape to find the area.

·         Allow students to compare their findings and discuss any differences.

Session 4: Applying Skills (60 minutes)

Objective: Apply the concept of area and non-standard units to real-world scenarios.

1.      Review (10 minutes):

·         Review the concepts covered so far.

2.      Real-World Examples (20 minutes):

·         Present students with scenarios where they need to find the area of irregular shapes using non-standard units.

·         Encourage them to brainstorm solutions and discuss their reasoning.

3.      Activity: Create an Area Poster (30 minutes):

·         Divide students into small groups.

·         Provide each group with a large piece of chart paper, markers, scissors, glue, and various materials to create shapes (e.g., coloured paper, fabric scraps).

·         Instruct them to create a poster demonstrating how to find the area of irregular shapes using non-standard units.

·         Allow time for groups to present their posters to the class.

Session 5: Assessment and Reflection (60 minutes)

Objective: Assess student understanding of finding area using non-standard units and reflect on their learning.

1.      Individual Assessment (30 minutes):

·         Distribute a worksheet with a variety of shapes for students to find the area of using non-standard units.

·         Circulate the room to observe students' methods and understanding.

2.      Group Reflection (20 minutes):

·         Have students return to their small groups.

·         Lead a discussion on what they have learned throughout the week.

·         Ask them to reflect on the challenges they faced and how they overcame them.

3.      Wrap-up (10 minutes):

·         Review key concepts and provide feedback on student performance.

·         Encourage students to continue exploring area measurement in their daily lives.

Extension: For further STEM integration, students could explore the relationship between perimeter and area, or investigate how changing the size or shape of a unit affects area measurements. They could also explore digital tools for measuring area, reinforcing computational skills.
