This worksheet gives students an opportunity to apply the concepts of addition and subtraction to add and subtract different decimal places less than 10 without regrouping. When adding or subtracting decimals, students understand the need to align the decimal points and use zeros as stop signs. They do not need to regroup numbers to find the answer on this worksheet. In this worksheet, numbers are laid one on top of another (vertical format). This encourages students to use the inherent place value structure to solve the problems.
