This lesson was designed around an interdisciplinary unit on space and the universe. However, it can be used on its own, as an interesting lesson on making complex estimations. To see what its all about, download the preview file. If you download the entire thing, you get the "answers" and teacher notes that go along with what I have created as a preview.
Enjoy--this one sparked some very interesting conversations in my classes.

I currently teach Pre-Algebra, Algebra, and Geometry to 7th and 8th graders in the Northern suburbs of Chicago. I have been teaching since 2004, and I have noticed that many of the units I'm looking for aren't already bundled in a nice package...so I made them myself! To help YOU, my fellow teachers, find the "bundles" I've been looking for! I have put much time into creating my supplemental materials and units. Through sharing and observation of my self-created lessons, colleagues have suggested that I find a way to share the materials I have created. I hope you find my materials helpful! PLEASE email me at: jkreiseder@yahoo.com if you have questions! If you have suggestions for my materials, please let me know. If I agree, I'll fix it and send you back an updated version.
