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: Find a Rectangular Prism's Surface Area (G-MG.A.1)
How the beat teaches it: Every slot gives a rectangular prism's length, width, and height — use SA = 2(lw + lh + wh) to find the total surface area, then build that many notes anywhere in the kit.
This is lesson 23 of 24 in RockBlocks Math, Grade 10, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Volume of Prisms and Pyramids,” covered find the Volume of a Prism or Pyramid (G-GMD.A.3). Next is Lesson 24, “Composite Figures — Real-World Geometry.”
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.
