Add and Subtract Hundredths and Thousandths less than 1 without Regrouping: Horizontal Worksheet

Students know the significance of aligning the decimal points and using zeros as placeholders while adding or subtracting decimals. They do not need to regroup to get the answer. 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.
