Quick 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.
- Students use perimeter and area to measure parallelograms, triangles and composite shapes.
- Students use knowledge of vegetables to (theoretically) plant out their garden beds.
Australian National Curriculum:
Mathematics Year 5:
- Calculate the perimeter and area of rectangles using familiar metric units (ACMMG109)
- Estimate, measure and compare angles using degrees. Construct angles using a protractor (ACMMG112)
- Choose appropriate units of measurement for length, area, volume, capacity and mass (ACMMG108)
Mathematics Year 6:
- Calculate the areas of rectangles using familiar metric units (ACMMG109)
- Convert between common metric units of length, mass and capacity (ACMMG136)
- Solve problems involving the comparison of lengths and areas using appropriate units (ACMMG137)
- Connect volume and capacity and their units of measurement (ACMMG138)
Syllabus Outcomes: MA3-10MG, MA3-11MG, MA3-12MG, MA3-16MG, MA3-9MG, MA3‑1WM, MA3‑2WM, MA3‑3WM.
Time required: 40 – 60 mins
Level of teacher scaffolding: Medium- teacher will need to demonstrate basic geometry on the board.
Resources required: Student Worksheet, rulers, graph paper.
Homework and extension opportunities: Students can create a garden bed and plant it out with vegetables. They can also price soil and wood and find out the amount and cost of materials required for the vegetable patch they have created.
Key words: Mathematics, garden, garden bed, perimeter, area, volume, geometry.
