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: Compare and Interpret Rate of Change (8.F.B.4)
How the beat teaches it: Every slot gives two input-output pairs from a function — divide the change in output by the change in input to find the rate of change, then build it anywhere in the kit.
This is lesson 12 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, “Evaluating Functions,” covered evaluate Functions (8.F.A.1). Next is Lesson 13, “Pythagorean Theorem: Finding the Hypotenuse.”
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.
