Add Hundredths less than 1: Horizontal Addition Worksheet

Students align the decimal points and add extra zeros to the right of the number before adding decimal numbers to ensure that each decimal has the same number of digits. Then, for the sum, students add digits at the corresponding places. 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.
