Complete multiples of 3 number search Set 20. Fun and challenging. Sharpen your mind.
Multiples of 3 (3, 6, 9, 12, 15, 18, 21...) follow a less obvious pattern than multiples of 2, but they're still highly learnable. Every third number in counting is a multiple of 3. These puzzles develop understanding of this important multiplication sequence, which is crucial for advanced mathematics involving fractions and algebraic thinking.
Multiples of 3 have a special property: the sum of their digits is also divisible by 3 (9 = 9, 12 = 1+2 = 3, 24 = 2+4 = 6). Learning this divisibility rule helps you verify candidates quickly and builds deeper number sense beyond simple memorization.
Best for number sense, math vocabulary, pattern recognition, and mixed puzzle practice.

A multiples of 3 number search asks you to find numbers like 3, 6, 9, 12, 15, 18, and so on inside a grid. Solvers must recall or mentally test divisibility by 3 as they scan.
Add the digits of a number together. If the sum is divisible by 3, the number is a multiple of 3. For example, 15: 1 + 5 = 6, which divides by 3 evenly.
These puzzles align well with grade 3 math standards where students begin learning the 3-times table and basic divisibility concepts.
