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: Area of Parallelograms and Trapezoids (6.G.A.1)
How the beat teaches it: A parallelogram's area is base times height — the base is how many BLOCKS you use. A trapezoid has two different bases, so it doesn't split into blocks as cleanly; just build its total area anywhere in the kit.
This is lesson 20 of 24 in RockBlocks Math, Grade 6, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Area of Triangles,” covered area of Triangles (6.G.A.1). Next is Lesson 21, “Surface Area.”
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.
