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: Comparing Numbers to 1000 (2.NBT.A.4)
How the beat teaches it: Every slot gives you a number by its hundreds digit and asks you to beat it, or lose to it — a bigger hundreds digit always makes the whole number bigger.
This is lesson 10 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, “Skip Counting by 5s, 10s, and 100s,” covered skip Counting to 1000 (2.NBT.A.2). Next is Lesson 11, “Ten More, Ten Less, Hundred More, Hundred Less.”
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.
