Students demonstrate their problem-solving ability as they work on this subtract tenths less than 100 worksheet. When subtracting decimals, students line up the decimal points and add extra zeros to the right of the number so that each decimal has the same number of digits. Students then subtract digits at each place to find the difference. 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.
