For Tanglin parents choosing Primary 5 Mathematics tuition, weekday or weekend should follow a specific learning need. A workable slot gives the child enough attention to explain a method and enough space to try it again.
Percentage comparisons offer a useful diagnostic. Saying that one quantity is a certain percentage more than another does not mean the reverse comparison uses the same percentage.
Start by checking which amount is the reference whole. Then confirm the actual teaching venue and current availability, allowing for meals, travel, recovery and a short independent follow-up.

Ask your child what the percentage is being measured against. In a ‘more than’ question, the comparison amount is the reference whole.
Two questions can use the same difference but different reference amounts. A pupil who looks only at the difference may give the same percentage in both directions.
The next teaching step is to attach 100% to the correct quantity. A labelled pair of bars can help make that decision visible before calculation.
A weekday lesson may help when a percentage comparison has recently caused difficulty at school. The teacher can work from the pupil’s original choice of whole.
Allow food and a pause after school and travel. A tired child may calculate a familiar percentage without checking the words that identify the base.
On another day, ask for the reference amount and difference before a full solution. This short task can test the crucial reading decision.

A weekend session may give room to discuss the same pair of quantities in both directions. That contrast can clarify why the denominator changes.
Keep the session focused enough to finish with a new independent question. More time available does not require more unrelated topics.
Plan a brief weekday revisit with changed quantities. The child should name the comparison base again rather than repeat the previous percentage.

Alicia has $60 and Tricia has $48. By what percentage is Alicia’s amount greater than Tricia’s? Also find the percentage by which Tricia’s amount is less than Alicia’s.
The difference is $60 − $48 = $12. For Alicia’s amount compared with Tricia’s, the reference amount is Tricia’s $48.
The percentage more is $12 ÷ $48 × 100% = 25%. Check that 25% of $48 is $12, and $48 + $12 = $60.
For Tricia’s amount compared with Alicia’s, the reference amount is Alicia’s $60. The percentage less is $12 ÷ $60 × 100% = 20%.
Both comparisons use the same $12 difference, but they use different wholes. That is why 25% more in one direction corresponds to 20% less in the other.
For a fresh attempt, compare 50 cards with 40 cards. The ten-card difference is 25% of 40, but 20% of 50.
Check both statements using the actual counts. This reasoning concerns relative quantities; it does not mean the larger collection has changed or that cards have moved between people.

In a three-pupil group, each child can identify the comparison base before percentages are calculated. The teacher can hear whether the wording or calculation needs attention.
A shared example should lead to separate fresh attempts. A correct group answer does not establish that every pupil has selected the whole independently.
Ask about matching by learning needs and individual feedback. Confirm the actual venue and available sessions before arranging attendance.

After several lessons, reverse the direction of a new comparison. Can your child explain why the difference stays the same but the percentage may change?
If the calculation is secure but the whole is not, return to the labels. If the interpretation is understood, address arithmetic slips separately.
Match the task to taught topics and the school’s current assessment scope. These original examples illustrate a teaching approach rather than a particular school’s next paper.
