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: Repeated Addition & Arrays (2.OA.C.4)
How the beat teaches it: Every slot arranges equal rows of something — build a rimshot row with the number of rows, and a second row with the total, added the same amount over and over.
This is lesson 5 of 23 in RockBlocks Math, Grade 2, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Odd and Even Numbers,” covered odd and Even Numbers (2.OA.C.3). Next is Lesson 6, “Building Fluency: Sums and Differences Within 20.”
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.
