Using Google to teach Standard Form

If you type the word ´Maths´ into Google, the search engine does 68, 000, 000 searches in 0.27 seconds.

For a homework task, I got the students to search different things and record how many searches were performed in set periods of time. The students could then convert these numbers into standard form. As a starter, I extended the homework with the following question:

If Google continued to search at the same rate for an enitre day, how many search results would be displayed?”

Addition: If you’re looking for an idea on how to relate standard form to the students reference frame, click the link to Nathan Kraft’s post on Texting Algebraic Expressions.
