This worksheet strengthens students' accuracy and strategic flexibility while they subtract thousandths less than 100 with regrouping. When subtracting decimals on this worksheet, students align the decimal points and use zero as a placeholder. They must also regroup the numbers to find the difference. In each problem, the numbers are laid out in the horizontal format. Students should try to use different strategies involving composing and decomposing numbers to solve these problems. This will help them develop flexibility and fluency.
