Earth By the Numbers is a collection of 28 math tasks relating to facts about the earth. The tasks contain a mixture of basic operations, decimals, measurement and powers of 10. I have incorporated some science vocabulary in the tasks. These cards provide a good math-science link.

There is a general consensus on most of the facts listed. A couple of the facts are not set in stone. On these I used the most accepted numbers. Large number names listed are the American names. Other countries have different names.
