Primary General Studies: Classifying Living Things and Biodiversity (Paper 1 (basics))

Paper one builds the basics of classification: the five vertebrate groups, six-legged insects, flowering and non-flowering plants, then simple multiplication and percentages.

Direct answers　Ask how many legs, how many body parts and how it reproduces, then calculate; answers need a group name plus a number.

IntermediateA spider has 8 legs. How many more legs than an insect?
IntermediateAmong a fish, a frog, a snake, a sparrow and a dog, the fish and the bird are one each. Which groups are the other three?
IntermediateA pond has 12 frogs, each with 4 legs. How many legs altogether?
ChallengeA school records 25 small animals, of which 15 are insects. What percentage are insects?
ChallengeThree kinds of insects, 6 of each: how many insects and how many legs?
ChallengeOf 8 flowering plants, 3 are monocotyledons. What percentage are dicotyledons?
Error redoA classmate says a spider is an insect because it has legs and crawls. What is wrong?

03　Answers and one-line notes

#	Answer	One-line note
1	Fish, amphibians, reptiles, birds and mammals.	All vertebrates have a backbone; they are sorted by skin, breathing and how they reproduce.
2	Six legs, that is three pairs.	Counting legs is the quickest test: six legs means an insect.
3	7 insects, so 42 legs.	Add the insects first, then multiply by 6: 7 × 6 = 42.
4	2 more legs.	8 minus 6 is 2; that difference is why a spider is not an insect.
5	Amphibians (frog), reptiles (snake) and mammals (dog).	Matching each animal to one of the five vertebrate groups avoids confusing a frog with a snake.
6	48 legs.	A frog is an amphibian with four legs; 12 × 4 = 48.
7	60 per cent.	Divide 15 by 25 and multiply by 100 to get 60.
8	18 insects and 108 legs.	Work out 3 × 6 = 18 first, then multiply by 6 to get 108.
9	62.5 per cent.	Dicotyledons are 8 minus 3, that is 5 kinds; 5 ÷ 8 × 100 = 62.5.
10	Insects have 6 legs and a three-part body; a spider has 8 legs and a two-part body, so it is an arachnid.	Classification uses fixed features, not shared behaviour such as crawling.

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.

After paper one, take paper two and sort out series against parallel in one pass.Tutor Registration →
