Students understand that when multiplying a decimal by a number ending in zeros, the product will have the decimal point shifted to the right by the same amount as the number of zeros in the multiplier. They practice this concept extensively while finding the missing number in multiply hundredths and multiples of 100 worksheet. 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.
