Grade 2, Lesson 22: Partitioning Rectangles: Rows and Columns

Math skill: Rows & Columns of Squares (2.G.A.2)

How the beat teaches it: Every slot splits a rectangle into equal-size squares — build the number of rows and the number of columns; two slots also ask for the total.

This is lesson 22 of 23 in RockBlocks Math, Grade 2, a free course where every lesson turns a math idea into something you can count, hear, and play. The previous lesson, 2D and 3D Shapes,” covered shape Attributes (2.G.A.1). Next is Lesson 23, Equal Shares: Halves, Thirds, and Fourths.”

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.
