Healthy Eating Habits

Children in Class 3 learn best when they can see, touch, and talk about what they are learning. This topic is no exception, as it involves everyday foods they see at home and school. Active learning lets them sort, plan, and taste, turning abstract ideas about nutrients into concrete experiences they can remember and apply.

Activity 01

Placemat Activity30 min · Small Groups

Sorting Game: Healthy or Unhealthy

Provide pictures or real samples of foods like apples, samosas, carrots, and colas. In small groups, students sort them into two baskets and justify choices with reasons like 'gives energy' or 'too much sugar'. Conclude with a class share-out.

Differentiate between healthy and unhealthy food options.

Facilitation TipDuring the Sorting Game, arrange the food pictures on a large mat so students can physically move them into groups, which strengthens memory through movement and discussion.

What to look forPresent students with pictures of various food items commonly found in India (e.g., roti, apple, samosa, milk, dal, biscuit). Ask them to sort these pictures into two columns: 'Healthy Choices' and 'Unhealthy Choices', and briefly explain their reasoning for two items.

Activity 02

Placemat Activity40 min · Small Groups

Meal Planner: Build a Day's Menu

Give food group cards representing roti, dal, veggies, fruits, and milk. Groups construct a full day's meals: breakfast, lunch, snack, dinner. They present plans, explaining nutrient balance.

Explain the role of different food groups in providing energy and nutrients.

Facilitation TipWhile students work on the Meal Planner, circulate and ask pairs to explain how their chosen foods provide different nutrients, guiding them to fill nutritional gaps with specific examples.

What to look forAsk students: 'Imagine you have a school sports day tomorrow. What three healthy food items would you choose to eat today and tomorrow morning to give you the most energy? Explain why you chose each item.'

Plate Puzzle: Balance Your Thali

Students draw or use cutouts to fill a paper plate with one item from each food group. Pairs check each other's plates against a balanced diet chart and suggest improvements.

Construct a balanced meal plan for a day, including various food types.

Facilitation TipFor the Plate Puzzle, pre-cut thali outlines and food cards so students can physically arrange portions, helping them visualise balance visually and kinesthetically.

What to look forGive each student a small slip of paper. Ask them to draw one food item from the 'grains' group and one from the 'fruits' group, and write one sentence about why these are important for their body.

Food Group Hunt: Classroom Scavenger

List food groups on board. Whole class hunts for related items in snack boxes or drawings around the room, then tallies findings to see if snacks are balanced.

Differentiate between healthy and unhealthy food options.

A few notes on teaching this unit

Use real foods whenever possible to make learning relatable, but always verify allergies first. Keep explanations simple and concrete, linking nutrients to their daily lives, like energy for playing or strong bones for jumping. Avoid overloading with scientific terms; instead, use everyday language like 'energy foods' or 'body builders.' Research shows that when students connect learning to their own experiences, misconceptions are more easily corrected.

By the end of these activities, students will confidently classify foods, explain why balanced meals matter, and design simple healthy menus for themselves. They will use food group vocabulary correctly and justify their choices with reasons grounded in energy, growth, and health.


Watch Out for These Misconceptions

  • During Sorting Game, watch for students who place sweets and fried foods under 'healthy' simply because they taste good.

    After sorting, ask students to run a short activity where they walk or jog for one minute after eating a piece of fruit and then after eating a biscuit. Have them notice which energy lasts longer before they feel tired, linking the activity’s outcome directly to the misconception.

  • During Meal Planner, watch for students who create menus with only grains like rice or roti.

    After they present their menus, ask peers to identify which food groups are missing and suggest specific proteins or vegetables to add, using the food cards as visual evidence to fill the gaps.

  • During Food Group Hunt, watch for students who believe fruits can replace vegetables entirely.

    During the tasting session, have students chart the colours and textures of fruits and vegetables they taste, then discuss how different colours often mean different vitamins, using the chart to correct the over-reliance on fruits alone.
