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: Add Within 1,000 (3.NBT.A.2)
How the beat teaches it: Every slot adds two numbers within 1,000 — since the sum is too big to build directly, build its hundreds, tens, and ones on three different instruments: kick holding the pulse, snare answering, hi-hat keeping steady time underneath.
This is lesson 7 of 24 in RockBlocks Math, Grade 3, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Rounding to the Nearest Hundred,” covered rounding to the Nearest 100 (3.NBT.A.1). Next is Lesson 8, “Subtracting Within 1,000.”
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.
