Add Thousandths less than 100: Horizontal Addition Worksheet

Students align the decimal points and add extra zeros to the right of the number before adding decimals to ensure that each decimal has the same number of digits. Then, for the sum, students add digits at the corresponding places. As the worksheet uses a horizontal format, it allows for more creativity when it comes to how the student solves the problem. In contrast, in the vertical format, students usually employ the standard method to solve.
