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: Volume of a Cylinder (8.G.C.9)
How the beat teaches it: Every slot gives a cylinder with radius 1 (so, using π ≈ 3, each layer's circular base holds 3 notes) and a height — the height is how many BLOCKS you use; build the total volume across exactly that many blocks.
This is lesson 16 of 24 in RockBlocks Math, Grade 8, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Distance Between Two Points,” covered apply the Pythagorean Theorem to Find Distance (8.G.B.8). Next is Lesson 17, “Volume of Cones.”
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.
