Add and Subtract Tenths and Hundredths less than 1: Horizontal Worksheet

To ensure that each decimal has the same number of digits while adding or subtracting decimals, students align the decimal points and insert additional zeros to the right of the number. Students then add or subtract digits at each place to find the answer. In this worksheet, students practice solving problems written in the horizontal format. How numbers are laid out in a problem affects the method a student employs to solve it. Therefore to develop actual fluency and mastery of multiple strategies, students must practice different formats.
