Grade 6, Lesson 9: Greatest Common Factor

Math skill: Greatest Common Factor (6.NS.B.4)

How the beat teaches it: Every slot gives two numbers — find their greatest common factor, then build that many quarter notes anywhere in the kit.

This is lesson 9 of 24 in RockBlocks Math, Grade 6, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, Operations with Decimals,” covered multiply and Divide Decimals (6.NS.B.3). Next is Lesson 10, Least Common Multiple.”

Every slot above (A, B, C, D) is its own question, and it’s a real, blank RockBlocks beat the whole time — the same drag-and-drop tiles, kit, tempo, sheet music, and drummer view as anywhere else on the site. Tap ❓ Questionin the corner to read the current slot’s problem, build your answer right in the grid, then tap ✓ Check Answerto grade it. Once you’re done, keep going: expand the beat, drop it into a Stack, or save a copy to your own page — nothing here overwrites the lesson itself, so every visitor still starts from the same blank slots.
