Six and eight have plenty of multiples, but which numbers belong to both lists? A Primary 4 child who understands that question has a clearer starting point than one who is merely memorising a procedure. For Tanglin Halt parents considering Mathematics tuition, that difference matters.
Choose a weekday when your child has enough energy after school and travel to generate, compare and check values. Choose a weekend when a rested start makes those decisions easier. A useful routine leaves space for a small independent attempt later.
Before choosing a slot, find out whether the child distinguishes multiples from factors and understands what ‘common’ asks. A short original attempt can make the teaching need specific.

Ask which relationship the numbers must satisfy
A multiple of six can be made by multiplying six by a whole number. A multiple of eight can be made in the same way with eight. A common multiple belongs to both sets.
Keep the first task focused on positive multiples. Ask your child to explain why a proposed number belongs to a list rather than accept an unexplained sequence.
If multiplication facts are uncertain, they may interrupt the comparison. If the facts are secure but ‘common’ is unclear, the tutor should teach the relationship between the two lists.
The first positive number in both lists
The positive multiples of 6 begin 6, 12, 18, 24, 30, 36, 42, 48. Those of 8 begin 8, 16, 24, 32, 40, 48. The smallest positive common multiple is 24.
Check it directly: 24 ÷ 6 = 4 and 24 ÷ 8 = 3, both whole numbers. Forty-eight is also common, but it is larger. The word ‘smallest’ determines which common value answers the question.
For a fresh check, compare the positive multiples of 4 and 10. Their smallest positive common multiple is 20. Ask your child to show that twenty belongs to both lists and that no earlier positive term matches.

Leave room for an organised comparison
A weekday can work well when the child has a genuine settling period. A rushed learner may mix the lists, skip a multiple or select the first conspicuous number without checking both conditions.
A weekend may offer more patience for organised working. Consider the actual time and nearby commitments, because a crowded day can remove that advantage.
For Tanglin Halt families, compare the whole journey to the confirmed teaching venue and home again. Confirm the available lesson time and class fit before arranging the rest of the week’s activities.

Connect the list to the check
Useful teaching shows how multiplication generates the terms and how division can test membership. The lists and checks express the same relationship in different forms.
Then vary the numbers. Include a pair where one is already a multiple of the other. For example, twelve is the smallest positive common multiple of four and twelve. Multiplying the two given numbers is not always the smallest answer.
In a 3-pax group, ask how each learner checks a new pair independently. A tutor should see whether the child can justify the common value and its being smallest, rather than only copy a matching term.

Check the meaning after a gap
Later in the week, offer a different pair and ask for the smallest positive common multiple. Leave the worked lists out of sight and give time for a valid method.
If the terms are generated incorrectly, target the facts or sequence. If the lists are accurate but the child picks a value from only one, return to the meaning of common. The next task should address the actual difficulty.
The better lesson day supports this process sustainably. Organised lists, meaningful checks and fewer adult cues provide useful evidence when reviewing the teaching plan.

Make the starting position clear
The Primary 4 Mathematics tuition overview provides the wider level route. Bring current school materials, one independent attempt and a note of the first step that needed help. Include the original working so the discussion can begin with your child’s own decisions.
The Tanglin Halt tutor guide describes enquiries for families considering the Bukit Timah teaching location near Sixth Avenue MRT, not a separate Tanglin Halt classroom. Confirm the venue and placement directly. The MOE primary curriculum and syllabus page provides the official curriculum route.
For a parent–student consultation, share your preferred weekdays or weekends, actual travel starting point and child’s usual energy pattern. Confirm the available lesson time, teaching venue and class fit before enrolment. Sign up after the starting position is clear and the weekly arrangement looks sustainable.
