Lesson summary
Students are asked to measure the perimeter and area of a range of garden bed shapes. They are also asked to explore how these shapes affect the materials required for creating garden beds and the number of vegetables that can be planted. As a result of this activity students are encouraged to apply their learning and build a garden of their own.
Learning intentions:
Students will...
- use perimeter and area to measure parallelograms, triangles and composite shapes
- use knowledge of vegetables to (theoretically) plant out their garden beds.
