David Ng started it. Kurt Van Etten improved it. And I heard about it from MathMom. Now, you’re invited to play, too. It’s fun!
Here Are the “Rules”
1. Search for your blog on Google. Try to find 5 different phrases that produce your blog as the #1 hit.
2. You may enclose the search phrase in quotes if necessary, but a search without quotes is preferred.
3. Score your search phrases based on the total number of hits. As Kurt wrote:
The ideal search phrase would have your blog being number one out of something like a million hits returned. As it turns out, this is much easier to do than it might sound.
My Results
I didn’t believe Kurt at first, but it turned out to be true. Using my Most Popular Posts list as a guide, I was able to come up with some pretty impressive (well, to me, at least) rankings. As of this writing, Let’s play math! comes up first for the following search phrases:
understanding number bonds (2.67M)
things to do with a hundred chart (2.09M)
teaching bar diagrams (1.88M)
let’s play math (1.79M)
egyptian math puzzles (1.68M)
[Results with SafeSearch on, which I suppose may skew the numbers somehow.]
Denise Gaskins' Let's Play Math 
Using math mama as my search gets 3.9 million results. :^)
That shows you picked a good name! 🙂
I haven’t tried this meme for awhile. It looks like I dropped down to 3rd place on “Egyptian math puzzles” and completely off the first page for “bar diagrams.” I wonder what I might be 1st at now…
