3D math game · Best for grades 2-4
Hundred Chart (Multiples Chart) puts a grid of 1 to 30 in front of students and asks them to colour every multiple of a given number. The coloured tiles reveal skip-counting patterns — diagonal stripes, evenly spaced gaps, and visual rhythms that turn abstract multiples into something students can see and remember.
Hundred Chart builds fluency with skip counting, multiples, and early times-table patterns. Visually spotting the evenly spaced intervals of 2s, 5s, or 7s reinforces the pattern structure of multiplication and lays the groundwork for understanding common multiples and divisibility rules.
Colouring multiples of 3 up to 30: tiles 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 light up. Students notice every third tile is coloured — the rhythm of 3 becomes visual. Switching to 6 shows every other tile from the 3s is coloured, making 3 and 6 share multiples visible.
Students often confuse multiples with factors and colour numbers that divide evenly into the target rather than numbers the target divides into. The prompt reminds them to colour numbers you reach by skip-counting, not the divisors of the given number.
Use it for individual practice, paired work, or a short class demonstration before worksheets.
