This is a series of twelve short tasks (with easy, medium, and hard levels) intended to introduce fifth grade students to the concept of powers of ten, place value, multiplying decimals by 10, and similar concepts. Some problems are closed-ended, while others are open ended. This problem set is intended to be used with students who have access to a calculator, though most of the problems could be solved without one.
The emphasis in this problem set is noticing patterns when multiplying and dividing by 10. One problem introduces the idea of exponents. This problem set was designed for a class of on- and below-level fifth grade students, though it could be used as an extension activity for a more advanced group of fourth graders. Symbols on each task indicate the task's level of difficulty.
Answer key included.
