Step 7: Evaluation/Review

Time: 5 mins

1. Name the six nutrient groups taught in this lesson.
2. Give two sources of carbohydrates.
3. State one function of protein.
4. Name two foods that can supply vitamins or minerals.
5. Why does the body need water?

Step 8: Conclusion

Lesson Keywords

• Nutrient – A useful substance in food that the body needs.
• Carbohydrate – A major source of energy.
• Protein – Helps growth and repair of body tissues.
• Vitamins and minerals – Help the body function properly and stay healthy.
• Water – Supports digestion, transport and temperature control in the body.

Lesson Evaluation

Pupils sort familiar Nigerian foods into nutrient groups and explain one main function of each group.

Assignment/Homework

Draw or list one meal eaten at home. Identify at least three nutrient groups supplied by the foods in the meal.

Differentiation

Use real foods or picture cards for pupils who need support. Ask advanced learners to explain why one food can sometimes provide more than one nutrient.

Note for Teachers

Avoid teaching that every food belongs to only one nutrient class. Many foods contain several nutrients; classroom grouping highlights the nutrient for which the food is a useful source.
