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 log base b of x Using Change of Base
How the beat teaches it: Every slot gives log_b(x) — the change-of-base formula log_b(x) = log(x) ÷ log(b) is how a calculator (which only has log base 10 or ln) evaluates any base. Find the value. Build that many notes anywhere in the kit.
This is lesson 13 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, “Holes vs. Asymptotes in Rational Functions,” covered find the y-Coordinate of a Removable Discontinuity. Next is Lesson 14, “Compound Interest — Future Value.”
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.
