About this app
Decimal Place Value is an interactive elementary math app that uses a 10Γ10 grid to represent decimals. Each small square equals 0.01 and each row of ten squares equals 0.1, helping learners build decimals, compare their sizes, and add decimals with or without carrying. Guided four-step missions provide practice for making target values, comparing A and B, and understanding when a full grid becomes 1.
