Assess students' ability to design a backyard vegetable garden plan by allocating bed space, calculating area and plant spacing to determine how many plants fit, estimating per-harvest and seasonal yields using simple rates, and selecting crops that suit given sunlight exposure and a fixed budget. Require clear calculations, unit use (e.g., square feet/meters), basic arithmetic (addition, subtraction, multiplication, division, simple fractions), and a written justification for crop and layout choices. Suitable for applied problem-solving tasks at an advanced elementary level.
