Sometimes a Primary 3 child knows the topic and still answers the wrong question. The problem is not always content. It can be the command word. Identify, describe, explain, compare, list, choose and support each ask the learner to do a different intellectual job.
Use This Beside the Primary 3 AL1 Vocabulary Hero
Use eduKateSG’s Top 100 Vocabulary List for Primary 3 (AL1 Grade) Advanced as the central vocabulary bank. This article focuses on school-command vocabulary: the small set of words that tells children what kind of answer to build.
Identify
To identify is to name or point out the relevant item. If the question asks, “Identify the character who found the wallet,” the child usually does not need a long explanation unless another instruction asks for one.
Describe
To describe is to give relevant features. “Describe the path” may require details such as narrow, muddy and slippery. Good description answers what something is like.
Explain
To explain is to make a relationship clear. Usually the learner needs a reason, cause, process or connection. Naming alone is not enough.
Compare
To compare is to examine similarities and differences according to a relevant feature. A strong comparison states the basis: size, behaviour, result, material, character or another dimension.
Contrast
To contrast focuses on difference. Children should not write two unrelated descriptions; they should show how the items differ on the same dimension.
List
To list is to provide the requested items. Extra explanation may be unnecessary. Understanding the command can save time.
State
To state is to give the answer clearly and directly. The expected depth depends on the subject and question, but the instruction itself does not necessarily ask for extended reasoning.
Support
To support an answer is to provide evidence, examples or reasons. In comprehension, this may mean quoting or referring to a detail from the passage in the child’s own words where appropriate.
Infer
To infer is to reach a conclusion from evidence rather than from an explicit statement. The answer should be plausible and grounded in the text.
Summarise
To summarise is to give the main information concisely. A summary removes less important detail while preserving the central meaning.
Sequence
To sequence is to place events or steps in the correct order. Vocabulary such as first, next, after and finally may help express that structure.
Classify
To classify is to group according to a rule or property. The child should know the basis for the grouping rather than sorting randomly.
Predict
To predict is to state what is likely to happen based on evidence or a pattern. It is not permission to invent anything at all.
The Command-to-Answer Map
- Identify → name it.
- Describe → tell what it is like.
- Explain → show why or how.
- Compare → show similarities and differences.
- Support → provide evidence.
- Infer → conclude from clues.
- Sequence → order the steps.
- Classify → group by a rule.
Why Command Words Matter Across Subjects
The same words travel through English, Science and Mathematics. Compare can apply to characters, materials or quantities. Explain can apply to motives, observations or methods. These are academic bridge words with unusually high value.
The Underline-the-Command Habit
Before answering, underline or mentally identify the command word. Then ask, “What job is this word asking me to do?” This tiny habit reduces avoidable mistakes.
The Wrong-Answer-Type Exercise
Give a correct fact in the wrong form. For an explain question, provide only a label. Ask what is missing. Children learn that correctness includes matching the response to the instruction.
The Same-Content, Different-Command Exercise
Use one topic and ask: identify the material, describe it, compare it with another material, explain why it is suitable. The content stays stable while the command changes the reasoning operation.
Do Not Teach Commands as Rigid Mark Schemes
Exact expectations vary by question and subject. Teach the conceptual job first. Children should understand what explain means before learning any exam-specific answering routine.
A Seven-Day Command-Word Cycle
- Day 1: identify, state and list.
- Day 2: describe.
- Day 3: explain.
- Day 4: compare and contrast.
- Day 5: infer and support.
- Day 6: classify, sequence and predict.
- Day 7: mixed unseen questions across subjects.
The Deeper Lesson: Instructions Are Part of the Curriculum
A child can only show what they know if they understand the action the question requests. Command vocabulary is not administrative language around learning. It is part of learning itself.
Primary 3 Question-Word Checkpoint
- Find the command word first.
- Know the reasoning job it requests.
- Match answer depth to the instruction.
- Use evidence when asked to support or infer.
- Compare on a shared dimension.
- Explain relationships, not just facts.
- Transfer command meanings across subjects.
- Read the whole question before answering.

Deep Command-Word Practice: Translate Instructions into Thinking Moves
Command words are small, but they behave like cognitive operators. They tell the learner what kind of mental action must happen next. A child who knows the content but misreads the operator can produce an answer that is factually correct and still does not satisfy the question.
Predict the Shape of the Answer Before Filling It
Before thinking about the topic, ask what shape the command requires. Identify often needs a name. Describe needs relevant features. Explain needs a relationship such as why or how. Compare needs a shared dimension. This prediction gives the child a template for the response without turning the answer into a memorised formula.
Describe Is Not Explain
“The leaf is yellow and curled” describes. “The leaf may be yellow because the plant is not receiving what it needs” begins to explain. The first states observable features. The second connects a condition to a possible reason. Children often lose marks or clarity because they answer one operation when the question asks for the other.
Identify Is Not Support
“Maya is nervous” identifies an emotional state. “Maya is nervous because she keeps checking the clock and biting her lip” supports the inference with evidence. If the question says “identify and support,” both jobs must appear.
Compare Is Not Two Separate Descriptions
“Leaf A is green. Leaf B is yellow” names two properties but only weakly compares. “Leaf A is green whereas Leaf B is yellow” places the two items on the same dimension. Strong comparison keeps the basis stable.
Predict Is Not Infer
A prediction looks forward: what is likely to happen next? An inference explains something not directly stated from evidence already available. The two can use similar evidence but point in different directions.
Read the Whole Instruction, Not Only the First Command
Questions may contain more than one operation: “Identify the character’s feeling and explain why.” “Compare the two materials and support your answer with one observation.” Children should mentally split the task into parts and check that each part is answered.
The Command–Target–Evidence–Scope Check
- Command: What thinking action is required?
- Target: What exactly must that action be applied to?
- Evidence: Does the question require proof, examples or working?
- Scope: One point, two points, a sentence, a sequence, or a full explanation?
This four-part check helps pupils avoid answering the right topic in the wrong way.
Worked Set: One Leaf, Five Different Questions
- Identify: What colour is the leaf? → Yellow.
- Describe: Describe the leaf. → It is yellow, curled and dry at the edges.
- Compare: Compare it with a healthy leaf. → It is yellower and more curled than the healthy leaf.
- Explain: Explain why it may be unhealthy. → The condition may indicate that the plant is not receiving what it needs.
- Support: Support your answer. → The leaf is yellow and curled, unlike the healthy green leaf.
The content barely changes. The command changes the intellectual operation.
Qualifiers Matter Too
Words such as using evidence from paragraph 3, in one sentence, give two reasons or based on the diagram narrow the task. A child can understand the command and still answer too broadly if these qualifiers are ignored.
Parent Practice: Ask “What Job Is the Question Asking?”
Before helping with content, ask the child to translate the instruction into plain English: “It wants me to name it,” “It wants me to show why,” or “It wants me to compare the same feature.” This preserves the child’s thinking while making the command visible.
Teacher Practice: Same Content, Different Operator
Take one familiar topic and write five questions using different command words. Pupils can see that academic vocabulary changes the response demanded even when the subject matter remains constant.
World-Class Command-Decoding Challenge
Choose six real school questions from English, Science and Mathematics. For each, underline the command, circle the target, box any evidence requirement and state the expected answer shape before solving the question. This separates task interpretation from content knowledge and makes command vocabulary transferable across subjects.
