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: Find dV/dt = 3s² · (ds/dt)
How the beat teaches it: Every slot gives a cube's side length s and how fast it's growing, ds/dt — the volume's rate of change is dV/dt = 3s²(ds/dt), found by differentiating V=s³ with respect to time. Build that many notes anywhere in the kit.
This is lesson 17 of 24 in RockBlocks Math, Calculus I, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Implicit Differentiation,” covered find dy/dx on a Curve Defined by xy = k. Next is Lesson 18, “Finding Critical Points.”
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.
