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 ∫2x dx From 0 to b Using the Fundamental Theorem
How the beat teaches it: The last lesson of Calculus I: every slot asks for the area under f(x)=2x from 0 to b — a triangle you could find with geometry, but here found with the Fundamental Theorem, tying together every lesson since limits: factor a limit, take a derivative, now reverse it into an integral. Calculus II picks up with harder integration techniques from here. Build that many notes anywhere in the kit.
This is lesson 24 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, “The Fundamental Theorem of Calculus,” covered evaluate a Definite Integral as F(b) - F(a). 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.
