Area & Perimeter Builder

Learning fit

Labels show who asserted each claim.

An area-and-perimeter lab for ages 8-12 built on one distinction: tiles cover the inside, a fence walks the edge. Tile & Fence Lab resizes a rectangle on a unit grid with live area (square units) and perimeter counts plus a same-area-different-fence comparison (6x4 vs 8x3 vs 12x2). Build the Yard sets 8 target challenges (a garden of area 18, a pen of perimeter 16) with badges. Which Is Which? runs 10 real-world rounds (carpet, photo frame, yard fence, poster ribbon) where kids first choose area or perimeter, then compute it.
