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: Unit Fractions (3.NF.A.1)
How the beat teaches it: Every slot shows a shape split into equal parts — the denominator is how many equal parts make the whole; build that many quarter notes anywhere in the kit, one for each part.
This is lesson 12 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, “Properties of Multiplication,” covered properties of Multiplication (3.OA.B.5). Next is Lesson 13, “Fractions on a Number Line.”
💻 Code it: In CodeBlocks, hihat(1, 2) splits a beat into halves and hihat(1, 4) into quarters, the same unit fractions in code. Try it in CodeBlocks.
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.
