Students represent, read, write, and expand nonnegative decimals through hundredths, identifying the ones, tenths, and hundredths places and connecting decimals with fractions, models, and equivalent forms. Students compare, order, and locate decimals through hundredths and add or subtract them by aligning place values and regrouping across ones, tenths, and hundredths. Students apply these skills to solve measurement and money problems involving tenths and hundredths, including interpreting quantities, finding totals, differences, costs, change, and unknown amounts.
