Add Decimals less than 100: Horizontal Addition Worksheet

Can your young mathematician add decimals less than 100? That's exactly what they do here. To ensure that each decimal has the same number of digits while adding decimals, students align the decimal points and insert additional zeros to the right of the number. Students then add digits at each place to find the sum. This worksheet is about practicing with the horizontal format in which numbers are written side by side. To develop flexibility with numbers and operations, students need to have enough practice in this format and not just rely on the vertical/column method.
