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: Evaluate a Limit by Factoring Out a Removable Discontinuity
How the beat teaches it: The last lesson of RockBlocks Math, K through 12: every slot is a limit of a rational function with a hole — the same factor-and-cancel move Grade 11 taught for simplifying rational expressions, just asked with calculus's own vocabulary now. Factor the numerator, cancel the shared factor, then plug the target value into what's left. Build that many notes on the crash cymbal, anywhere you like in the beat — and if you've built one lesson from every grade along the way, this is the one to finally drop them all into a single long Stack and hear the whole run, kindergarten to here, back to back.
This is lesson 24 of 24 in RockBlocks Math, Grade 12, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, “Expected Value,” covered calculate the Expected Value of a Random Variable (S-MD.A.2). It is the final lesson in this grade.
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.
