About this worksheet

Expanded <-> Standard Form Color by Number turns a key place value & rounding skill into a picture students actually want to finish. Students solve each problem, match the answer to the color key, and a hidden picture appears region by region. Students convert between expanded and standard form. Built for Grades 2–5 and aligned to 2.NBT.A.3, 4.NBT.A.2, 5.NBT.A.3. No-prep and self-checking, it's ready for math centers, morning work, early finishers, or homework — and every download includes a print-ready PDF plus an interactive version with the answer key.
