For an Alexandra family choosing Primary 4 Science tuition, a helpful starting question is not “Which day is better?” but “What should my child be able to explain afterwards?” A lesson time becomes easier to evaluate when the learning target is small enough to see.
Imagine a bar magnet divided across its middle in a worksheet drawing. A child labels one piece north and the other south, as though the poles were two detachable ingredients. The picture has changed, but the child’s rule has not changed with it.
This guide uses a paper-only magnet example to compare weekday and weekend learning rhythms. It is not an instruction to break, cut or heat magnets. Match the example to current schoolwork and readiness; a level label does not establish when every school teaches a particular topic.

CHAPTER 1 OF 10 • Identify the learning question
1. Find the rule behind the pole labels
Ask your child what they think happens at the newly exposed ends. A pupil may remember the original north and south labels correctly but leave the new ends unlabelled. Another may believe the entire left piece is north and the entire right piece is south.
Those responses are different from confusing which original end was north. Start by locating the actual difficulty. If the original orientation is understood, the next teaching move concerns what each shorter magnet is, not another exercise in remembering the first two labels.
Bring the troublesome drawing to a tuition discussion. A tutor can ask the child to explain before marking the answer. That reveals whether the child treats a magnet as having a pair of poles or treats the two poles as separable halves.
In the ordinary idealised bar-magnet model used here, dividing a magnet does not produce an isolated north-only piece and south-only piece. Each shorter piece has a north pole and a south pole. The question assumes the pieces remain magnetised and retain the original magnetisation direction.
NASA’s archived explanation of magnetic poles describes this distinction. The concept is stable, although the page is an archive rather than a source of current programme information. No advanced discussion of magnetic materials is needed for the paper task.
Treat pole labels as properties of ends, not names for entire chunks of material. That small language change can help a child draw the correct pair. It also keeps the explanation clear when a shorter piece is later turned around.
CHAPTER 3 OF 10 • Inspect the case and weekday fit
3. Label a worked case from left to right
A drawing shows an original bar with N at the far left and S at the far right. It is divided at its middle. Both pieces remain in their original orientation, with a gap between them. Call the left piece A and the right piece B.
A has N at its outer left end and S at its newly exposed right end. B has N at its newly exposed left end and S at its outer right end. The two facing new ends are therefore unlike poles and attract in this idealised arrangement.
Ask the child to give the pole pair for each piece before predicting attraction. That order makes the reason visible. “They were once joined” is not the appropriate pole rule; the prediction should follow from S facing N.
| Piece or arrangement | Left end | Right end | Relevant interaction |
|---|---|---|---|
| A, original orientation | N | S | A’s new S faces B’s new N |
| B, original orientation | N | S | Facing unlike poles attract |
| B after end-for-end rotation | S | N | A’s S now faces B’s S; like poles repel |
CHAPTER 4 OF 10 • Inspect the case and weekday fit
4. Check whether a weekday evening supports discussion
A weekday lesson may help when the child can still explain the thought behind a recent school answer. Yet a clear memory of the question is not enough if the rest of the evening is crowded. Consider meals, rest, other homework and bedtime alongside the lesson.
Use a normal school day as the test, rather than an unusually quiet one. Can your child discuss why a new end needs a pole label? Can a later short recall fit on another day without a parent having to reteach the full diagram?
A workable follow-up might be one altered orientation on paper. Ask the pupil to label before predicting. If the check repeatedly depends on adult hints, tell the tutor what those hints are. The routine should make the gap easier to see, not easier to conceal.
CHAPTER 5 OF 10 • Connect the routine with explanation
5. Let a weekend lesson connect to weekday recall
Weekend teaching can create space for slower explanation and comparison. A child may need to see that each piece has a pair before a rotated drawing makes sense. Give the pupil time to reason; do not fill every pause with another clue.
Plan a separate schoolweek return to the idea. A suitable task might show one shorter magnet turned around and ask which end now faces another magnet. Keep it within the lesson’s scope rather than introducing several new variables at once.
The weekend plan should also leave room for recovery and family commitments. A longer sitting is not automatically more effective. Once the child can label independently and explain the interaction, agree on a useful stopping point and the next small check.
CHAPTER 6 OF 10 • Connect the routine with explanation
6. Separate rotation from a change of pole identity
If piece B in the worked drawing is turned end-for-end, its S end now faces A’s S end. The facing like poles repel. Turning a magnet changes which end points toward another object; it does not rename a particular physical end from S to N.
Let your child describe the end that moved before giving the interaction. This is a useful check for a pupil who can recite like poles repel but struggles to track a drawing. The issue may be spatial reading rather than the attraction-and-repulsion rule.
Do not infer an exact force or distance moved from a pole diagram. Nor does division alone provide a simple numerical strength ratio for all real magnets. This task asks for pole identities and the qualitative interaction under stated conditions.
Use the question below after the worked answer is no longer in view. It changes the number of pieces rather than merely swapping the original labels. Read the assumptions carefully so the child answers the described model, not an imagined practical experiment.
Ask for both ends of each piece. A response listing only the original outer ends can look partly correct while missing the essential repair. The new ends are the most informative part of this check.
Afterwards, distinguish an incomplete label from an incorrect rule. If the pupil knows each piece has two poles but omits one while drawing, the next step may be a completion check. If they still believe a piece has only one pole, revisit the model.
Independent check
A paper drawing shows a bar magnet with N on the left and S on the right, divided into three shorter pieces. The question states that all pieces remain magnetised, retain the original magnetisation direction and stay aligned in their original orientation. What poles are at the left and right ends of each piece? Are the facing ends of neighbouring pieces like or unlike poles?
Checking notes
Each piece has N at its left end and S at its right end. Each gap has S facing N, so the facing ends are unlike poles and attract in the stated model. There are three north–south pairs, not a north-only first piece, a poleless middle piece and a south-only last piece.
A fair review of weekday and weekend options uses comparable tasks. Do not judge one arrangement by a familiar two-piece example and another by a complicated set of magnets with several rotations. Match the follow-up to the learning target actually taught.
Useful evidence includes lesson readiness, the child’s explanation and a later independent diagram. Keep notes brief. One difficult evening or one fluent answer should not become a fixed description of your child’s ability.
Confirm available times, three-pupil group composition and actual travel arrangements directly. This guide is for Alexandra parents considering support; it does not announce a local branch or a particular commuting time. The comparison table is a planning aid, not a results guarantee.
| Checkpoint | Weekday option | Weekend option |
|---|---|---|
| Starting point | Recent school drawing can be discussed | Time to compare original and rotated views |
| Later check | A separate calm paper question | A small return during the school week |
| Learning signal | Labels the newly exposed ends | Tracks physical ends after rotation |
| Confirm directly | Actual availability and group fit | Actual availability and group fit |
Should we break a magnet to demonstrate the idea? No. Use the stated paper model. Breaking or cutting magnets can create sharp fragments, and a practical activity is unnecessary for answering this question.
Does turning a piece reverse its pole labels? It changes the direction in which the ends point, not the identity of each physical end. Track the moving end before deciding which poles face each other.
What should I ask about a three-pupil lesson? Ask how each child labels a changed diagram independently. Hearing another pupil’s reasoning can be useful, but a three-pupil format still needs individual checks to establish who understands the new ends.

10. Choose a time around the next independent diagram
Make the teaching request concrete: “My child should recognise that every shorter magnet in the stated model has both poles and track those ends after rotation.” Add the relevant school question and your realistic weekday or weekend openings.
