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: Addition Word Problems (K.OA.A.2)
How the beat teaches it: Every slot is the same idea as Lesson 11's facts, but wrapped in a tiny story — a drummer plays some quarter notes, then a few more join in.
This is lesson 13 of 24 in RockBlocks Math, Kindergarten, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Subtracting Within 5,” covered fluently Subtract Within 5 (K.OA.A.5). Next is Lesson 14, “Ways to Make 5.”
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.
