This worksheet strengthens students' accuracy and strategic flexibility while they add and subtract hundredths less than 100. In this worksheet, students add and subtract decimals by aligning the decimal points and using zero as a placeholder. They then use the relationship between addition and subtraction to find the missing number in the add and subtract hundredths less than 100 worksheet. 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.
