Assess students' ability to plan a balanced school lunch for grades 3–5 by selecting items from the five food groups (fruits, vegetables, grains, protein, dairy or alternatives), specifying age-appropriate portion sizes (e.g., cups, ounces, pieces), and explaining how the choices provide balance, variety, and suitable energy for elementary learners; include one complete sample lunch, labeled portions, and brief justification plus one simple swap for a common dietary preference or allergy.
