Six hands-on tools & the concept quiz

Pick a tool and start measuring. Everything runs on your device; nothing is sent anywhere.

Measure Lab Read an object’s length off a ruler — including the tricky "broken ruler" where it does not start at zero, so you subtract instead of reading the end. Length Convert Lab Step up and down the metric staircase (mm · cm · m · km) and swap customary units (in · ft · yd, oz · lb, cups · quarts) — multiply going down, divide going up. Unit conversion Balance Scale Load unit weights onto a pan until the scale balances a fixed load — and feel why 1 kg = ten 100 g weights, or 1 L = four 250 mL cups. Equivalence Area & Perimeter Builder Count square units for area and edge units for perimeter on a grid — then solve the puzzle: with the same fence, which shape holds the most space? Geometry Data Studio Read bar graphs, find the mean, median, mode and range — and tally your own shapes into a graph you build, then read it. Data & stats Estimation Station Place a value on a number line with no tick marks, lock in your guess, and see exactly how close you were. Sharp estimates make every measurement easier. Estimation Concept Kits 16 quiz kits — 400 questions from reading a ruler to statistics — with a hint after a first miss and an explanation every time. Practice
