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: Evaluate ∫3x² dx From 0 to b
How the beat teaches it: The last lesson of the Calculus track: every slot evaluates ∫[0,b] 3x² dx = b³ — the same Fundamental Theorem Calculus I ended on, one course later. From College Algebra's systems, through Statistics' data, through Calculus I's derivatives, to every integration technique this course added, it all still comes down to substituting into a clean antiderivative. Build that many notes anywhere in the kit.
This is lesson 24 of 24 in RockBlocks Math, Calculus II, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Polar Coordinates — Finding r,” covered convert a Rectangular Point to Its Polar Radius. It is the final lesson in this grade.
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.
