Assess students' ability to apply knowledge of the five basic food groups (fruits, vegetables, grains, protein, dairy) to plan a balanced school lunch: select appropriate items from given options, assign simple portion counts using whole-item or single-serving units (e.g., 1 fruit, 1 vegetable, 1 grain, 1 protein, 1 dairy), and write a brief justification explaining how their choices provide balance, variety, and age-appropriate portions for Pre-K to Grade 2.
