Don’t tell anyone, but Greg Tang Math penetrated my incredible resistance to e-mail spam and persuaded me to visit the site out of curiosity. I’m not really sure why the persistent e-mails that I kept trashing finally grabbed my attention, but I obviously wouldn’t be writing this post if they hadn’t eventually been successful. (If you happen to be a spammer, please don’t think I am encouraging you to try the same strategy; I can promise you that it was a one-time-thing…)
The good news is that I actually found some unique math materials on the site. There are plenty of free resources that you can download, and even some interesting online math games. For gifted students, the Kakooma and Expresso pages are great challenges. (There is also an online version of Kakooma on this page.) In addition, there are some printable math games on the resources page.
Of course, there are plenty of things you can purchase on the site. Otherwise, what would be the purpose of the e-mail barrage? But I think that you will agree that there is a generous dose of free materials, which makes some advertising bearable 🙂
