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: Place Value (1.NBT.B.2)
How the beat teaches it: Every slot gives you a two-digit number — build its tens on the bass drum and its ones on the hi-hat, the same two rows every time.
This is lesson 17 of 24 in RockBlocks Math, Grade 1, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Skip Counting by 10s,” covered counting by Tens (1.NBT.A.1). Next is Lesson 18, “Ten More, Ten 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.
