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: Find the Length of a Hyperbola's Transverse Axis
How the beat teaches it: Every slot gives a hyperbola in standard form x²/a² - y²/b² = 1 with a perfect-square denominator under x² — take its square root to get a, then double it for the transverse axis length, 2a. Build that many notes anywhere in the kit.
This is lesson 21 of 24 in RockBlocks Math, College Algebra, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Standard Form of an Ellipse,” covered find the Length of an Ellipse's Major Axis. Next is Lesson 22, “Partial Fraction Decomposition.”
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.
