About this app

Area and Units is an interactive elementary math activity about measuring area and converting squared units. Learners place and count 1 cm unit squares, adjust width and height to meet area goals, and explore why a 100-fold length change produces a 10,000-fold area change. Practice problems cover multiplication and conversions such as m² to cm² and km² to m².
