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: Counting Patterns (2.NBT.A.2)
How the beat teaches it: Every slot is a counting-by-5s sequence with one number missing — build how many FIVES that missing number is, not the number itself.
This is lesson 3 of 24 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, “Subtraction Facts Within 20,” covered fluency Within 20 (2.OA.B.2). Next is Lesson 4, “Ten More, Mentally.”
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.
