Quickly multiplying numbers by a power of 10 is an important skill for students to learn. The ability to perform these calculations quickly, accurately, and without a calculator can be especially useful. Students will encounter this type of multiplication inside and outside the classroom.
Some examples of when students will encounter multiplying by a power of ten include working with scientific or engineering notation, metric units, and when doing many types of mental math. Powers of ten are the basis of scientific and engineering notation. Students will often need to convert numbers into and out of scientific or engineering notation when working with these numbers. This task requires multiplying numbers by a power of 10. Students will also encounter these types of calculations when converting metric units. All metric unit prefixes are a multiple of 10 and converting from a smaller unit to a larger unit requires multiplication by a power of ten. Additionally, students may find this type of multiplication useful when doing some types of mental math. For example, when multiplying 3000 by 22 it may be simpler for a student to split up the problem. They could multiply 22 by 3, then multiply 66 by 1000. This worksheet is designed to help students practice this useful math skill.
