This fun and interactive project helps students to order rational numbers expressed in both standard and scientific notation. The document gives the heights of several animals in centimeters. You can have your students pick several and organize into a table, and then order these numbers from least to greatest.
There is some self-regulation here, students will know they have done something wrong if they think a whale is smaller than a mosquito.
Enjoy! My 8th graders and 9th graders had a good time with this. If time permits, you could have them measure a partner's height and place their partner on the number line too.
