Factors and multiples for kids in Sengkang can begin with eighteen drawn activity cards. Which equal-sized groups can use every card without a remainder, and which totals can be built from groups of six?
This family guide separates factors from multiples through drawings, multiplication facts and simple checks. The focus is positive whole numbers and positive factors, with the scope stated clearly.
The activity counts are fictional, not records of a Sengkang school or library programme. Drawings are enough; children do not need small loose counters or a large collection of materials.

Three is a factor of eighteen because 18 divided by 3 equals 6 with no remainder. Eighteen cards can form six groups of three. Five is not a factor because complete groups of five leave three cards.
Ask the child to connect the division with multiplication: 3 × 6 = 18. A factor divides the number exactly in this whole-number activity.
For eighteen, the positive factor pairs are 1 and 18, 2 and 9, and 3 and 6. The complete list of positive factors is 1, 2, 3, 6, 9 and 18.
Write each pair as a multiplication fact. Pairing helps avoid missing a factor or listing the same factor twice. Zero cannot be used as a divisor.
Positive multiples of six include 6, 12, 18 and 24, produced by multiplying six by 1, 2, 3 and 4. The list continues rather than ending at twenty-four.
Zero is also a multiple of six mathematically, but this exercise deliberately lists positive multiples. State the scope instead of suggesting that every multiple must be positive.
Six is a factor of eighteen, and eighteen is a multiple of six. Both statements describe the same multiplication relationship from different directions.
Do not reverse the labels without checking: eighteen is not a factor of six in this positive whole-number setting. Ask which number divides which, and verify the result rather than rely on a memorised phrase.
The positive factors of six are 1, 2, 3 and 6; those of nine are 1, 3 and 9. Their common factors are 1 and 3, so the greatest common factor is 3.
Their least positive common multiple is 18: it appears in both positive-multiple lists. A common factor and a common multiple answer different questions, even when the original pair of numbers is unchanged.
Imagine organising eighteen title cards for a Sengkang family reading activity. Ask whether rows of two, three or four can all be complete. Two and three work; four leaves two cards.
North Vista Primary School emphasises mathematical reasoning and application. These independent activities share that broad emphasis. Our Sengkang multiplication-array guide offers a related way to make equal rows visible.
