Does your child know how to add and subtract decimals less than 10? Invite them to practice this concept here. 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. 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.
