Add decimals with carrying

Add two decimals with the same or different number of decimal places by aligning the decimal point and adding column by column from right to left. When a column's sum reaches 10 or more, regroup (carry) into the next column to the left, the same way whole-number addition works. Students will also practice treating a missing decimal place as a zero.
