How do I count five a day?

Three portions of vegetables plus two of fruit; a portion is about half a bowl of cooked vegetables or one medium fruit.

How is BMI worked out?

Weight in kilograms divided by height in metres squared, so 36 kg and 1.2 m gives 25.0.

03　Answers and one-line notes

#	Answer	One-line note
1	Grains such as rice, noodles and bread.	The base of the food pyramid is grains, our main source of energy.
2	At least 20 seconds.	Twenty seconds is about two rounds of Happy Birthday and removes most germs.
3	9 to 11 hours a night.	Too little sleep harms memory and attention, and growing children need more.
4	At least 5: 3 vegetables plus 2 fruit.	Two fruit plus three vegetables make 5 servings in total.
5	Protein.	Protein from meat, fish, eggs and beans builds tissue, while carbohydrates give energy.
6	To replace lost water and salts and avoid dehydration.	Sweating loses water, and dehydration causes dizziness, cramps and poor temperature control.
7	BMI = 36 ÷ (1.2 × 1.2) = 25.0.	BMI is weight divided by height squared: 36 ÷ 1.44 = 25.0.
8	420 minutes.	Sixty minutes times seven days gives 420 minutes, about seven hours.
9	It supplies morning energy, keeps blood sugar steady and helps attention and memory.	Skipping breakfast lowers blood sugar, causing tiredness and poor concentration.
10	Rinse the cut with clean water, press to stop the bleeding, then cover it with clean gauze.	Rubbing harms the wound; rinse, press and cover instead.

04　What to do after marking

After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
Repeat the same item two days later; move to the next paper only when both attempts are correct.
Parents only need the answer and note columns; there is no need to explain every item.
