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: Simple Interest (7.RP.A.3)
How the beat teaches it: Every slot gives a principal, a rate, and a number of years — the years are how many BLOCKS you use, and one year's interest is about how many notes go in each block; build the total interest across exactly that many blocks.
This is lesson 6 of 24 in RockBlocks Math, Grade 7, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Percent Decrease,” covered percent Decrease (7.RP.A.3). Next is Lesson 7, “Adding Integers.”
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.
