4/4 ×2
Drag rhythmic values into up to 8 beat blocks per line to build a drum groove, or click a tile then click a block to place it — handy on a trackpad.
Math skill: Solve Quadratic Equations by Factoring (A-REI.B.4b)
How the beat teaches it: Every slot is a quadratic that factors into two binomials — factor it, then read off the two roots, and build the smaller one on the high tom and the larger one on the rimshot.
This is lesson 21 of 24 in RockBlocks Math, Grade 9, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Factoring Trinomials,” covered factor Trinomials of the Form x² + bx + c (A-SSE.B.3a). Next is Lesson 22, “The Quadratic Formula.”
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.
