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: Multiplication as Equal Groups (3.OA.A.1)
How the beat teaches it: Every slot shows equal groups — the number of groups is how many BLOCKS you use, and the group size is about how many notes go in each one. Build the total across exactly that many blocks, anywhere in the kit, in any rhythm you like — a groove literally shaped like the multiplication.
This is lesson 1 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. It is the first lesson in Grade 3, so it assumes no prior math or drumming. Next is Lesson 2, “Multiplication Facts.”
💻 Code it: In CodeBlocks, a loop inside a loop plays 2 equal groups of 4 beats, and m * 4 + b finds every one of the 8. 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.

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.
