Multiplying and Dividing Decimals by Powers of 10
A guide outlines twenty-seven worksheet sets for multiplying and dividing decimals by 10, 100 and 1000, beginning with visual place-value tables and gradually removing the scaffolding until students shift the decimal point without support. Students who need that visual place-value foundation before removing the scaffolding can start with a decimal place value chart . Separate worksheet sets practice multiplication alone, division alone, and combined operations at each power of ten, followed by challenge sets that ask students to find a missing multiplicand, multiplier, dividend, or divisor rather than just compute an answer, and a set of word problems such as a bug that grows 1000 times its size or a cargo ship's tonnage divided among 100 containers. Later sets extend the pattern to powers of ten written with exponents rather than the numerals 10, 100, and 1000. Each individual worksheet pairs a page of problems with a matching answer page, and the accompanying guide explains how to sequence, randomize, or repeat any set for stations, homework, or substitute-teacher folders.
