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: Making 10 (1.OA.C.6)
How the beat teaches it: Every slot asks a different question with the same answer: what goes with this number to make 10? Build the total of 10 every time, however you split it.
This is lesson 10 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, “Counting On,” covered counting On (1.OA.C.5). Next is Lesson 11, “Bridging Through 10 to Add.”
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.
