Add and Subtract Hundredths and Thousandths less than 100: Horizontal Worksheet

When adding or 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 add or subtract digits at each place to find the answer. 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.
