Factor Forge: Factors Game for Grades 4‑6
Smelt numbers into factors, primes and common multiples before the fire dies.
Work the forge: break glowing number ingots into factor pairs, tap every factor or multiple, sort primes from composites, and hammer out the greatest common factor or least common multiple. Three levels take you from grade 4 factors and primes to grade 6 GCF, LCM and the distributive property.

What kids practise
Factor Forge gives students repeated, low-pressure practice with factors, multiples, prime numbers, composite numbers, greatest common factor, and least common multiple. It is written for grades 4-6, with levels that let younger and older players start at the right difficulty. Every question is generated fresh, so a replay is never the same, and a wrong answer shows the correct one so the round teaches as well as tests.
How it plays
Controls: Tap or click ore chunks and answer buttons, or press the number keys 1-8 to pick a tile. Press Enter on the Next button to continue. P pauses, M mutes.
It works with a keyboard, a trackpad or a touch screen, so it runs on school Chromebooks, tablets and phones.
