Primary General Studies | Food Pyramid and Balanced Diet (for tutors) | Five levels, daily portions, three meals

Tutor lesson-prep guides · Primary General Studies

Pupils know they should eat more vegetables but cannot say how much. This lesson turns balanced into a number they can add up: five levels and thirteen daily portions.

Objectives — Pupils can: (1) name the five levels and the rule that lower levels are larger; (2) use the daily minimums (6 grain, 3 vegetable, 2 fruit, 2 protein) to divide portions across three meals; (3) convert half a bowl of rice into one portion and check their own day.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Food groups	What broad groups of food exist?	Grains, vegetables and fruit, meat, dairy, fats
Sharing	How do 6 portions split over 3 meals?	2 portions per meal
Capacity	About how much is a bowl of rice?	About 250 millilitres

02 Lesson flow (60 minutes)

Time	Stage	Tutor does	Student does
0-6 min	Hook	Fried chicken meal versus a balanced meal; which is better	One reason each
6-16 min	Five levels	Draw 5 levels, two examples each	Groups of four fill the table
16-30 min	Daily portions	Grain 6, vegetable 3, fruit 2, protein 2	Add the total
30-42 min	Three meals	6 grain portions over 3 meals gives 2 each	Fill a meal table
42-54 min	Conversion	One portion is half a bowl (125 ml); a bowl is 2 portions	Convert twice
54-60 min	Exit check	Three questions collected and marked	Work alone

03 Teaching script (read it out)

Scene 1: Teach the shape first, not the food list

The pyramid has 5 levels and grows wider at the bottom: grains at the base, then vegetables and fruit, then meat, fish, eggs and beans, then dairy, with fats, oil, salt and sugar at the top.
Have pupils count the levels upwards with a finger and repeat that higher means less. That single rule answers the common question about which level should be smallest.

Pupils do: place crisps, rice, broccoli, an egg and milk onto the right level.

Scene 2: Portions are arithmetic, not advice

Daily minimums: 6 grain, 3 vegetable, 2 fruit and 2 protein portions, which is 13 portions in all. Spread over 3 meals that is 2 grain and 1 vegetable portions per meal.
The most useful conversion is rice: a bowl is about 250 ml, which is 2 portions, so one bowl at a meal already meets the grain target.

Pupils say: after one portion of porridge at breakfast, how many grain portions are still owed.

Scene 3: Close with a real menu

Ask pupils to write what they ate yesterday and score it against the pyramid: which level went over, which fell short.
Then ask one question only: which single meal will you change. The answer must be one concrete swap, such as crisps for fruit, so the lesson ends in an action rather than a slogan.

Pupils do: write an improved version of one meal with the portions labelled.

04 Question types and worked steps

Type	Example	Steps	Answer
Classify	Foods onto five levels	Name the group, then the level	Fats and sugar sit at the top with the smallest share
Portion sum	6 portions over 3 meals	Divide the total by meals	State any remainder clearly
Menu review	Compare two menus	Score level by level, then advise	Quote at least two numbers
Conversion	How many portions in a bowl	250 divided by 125	Answer 2 portions

Sanity check (teach this): Check the arithmetic: the pyramid has 5 levels; the four minimums add to 13 portions; 6 grain portions over 3 meals is 2 per meal; a 250 ml bowl is 2 portions, so half a bowl of 125 ml is one portion.

05 Independent practice (3 questions)

Question	Answer	What to watch
Five levels	Ten foods onto levels	Watch for crisps placed at the base
Portion total	6 plus 3 plus 2 plus 2	Answer 13 portions
Meal split	Fill the three-meal table	Each meal total must be sensible
Menu rewrite	Write one day of meals	Every level must reach its minimum

06 Common mistakes and what to say

Mistake	Student writes	Say this
Pyramid upside down	Meat assumed to be the base	Lower means larger; meat sits on the third level, below vegetables.
Portions read as bowls	6 portions means 6 bowls of rice	A portion is half a bowl, so 6 portions is 3 bowls, not 6.
Variety without quantity	I eat vegetables so I am balanced	How many portions? You need 3, which is one per meal.
Top level read as zero	Fats and sugar must be avoided entirely	The top means as little as possible, not none; the body still needs some fat.

07 Homework (paper, section and question numbers)

Balanced diet exercises — Questions 5 to 8: classification and portions
Prep guide index — Compare similar chapters
Redo this chapter — Write one day of meals with portions per level

08 Exit check (last 5 minutes)

Question	Answer	Decision
How many levels	5	Answer three means act one again
Daily minimum total	13 portions	Answer as many as possible means act two again
Portions in one bowl	2	Answer one means repeat the conversion

09 Tutor FAQ

Are portion targets the same for everyone?

They vary with age and activity; younger pupils use the lower end, and the ratio matters more than the exact number.

Are snacks banned?

They sit at the top, which means occasionally and in small amounts, not never.

Should we teach calories?

Portions are enough at primary level; calories belong to secondary biology or PE.
