EE.1.3

Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 × 10^8  and the population of the world as 7 × 10^9, and determine that the world population is more than 20 times larger.

Achievement Level Descriptors Logo. Includes a dark gray document symbol on a yellow background.
Illustrative Mathematics: Students are comparing very small and very large quantities using the metric system. This is especially convenient when comparing measurements using scientific notations since different units within the system are related by powers of ten.

Ant and Elephant

Achievement Level Descriptors Logo. Includes a dark gray document symbol on a yellow background.
Illustrative Mathematics:The purpose is for students to develop a feel for large powers of ten, which is a critical component of working fluently with numbers in scientific notation. This task develops very large ``number sense``.

Order of Magnitude

Achievement Level Descriptors Logo. Includes a dark gray document symbol on a yellow background.
Illustrative Mathematics:The goal of this task is to give students a context to investigate large numbers and measurements. Students need to fluently convert units with very large numbers in order to successfully complete this task. Four solutions are offered to support different ideas.
