GET YOUR NERD ON: It’s time to become a virtual nerd (unless you already have). This week, Pearson launched Virtual Nerd Mobile Math, a free iOS math app that offers 1500+ tutorials aligned to standards, including Common Core. Built out of the startup Virtual Nerd (which Pearson acquired last year), the tutorials are designed for 6th-12th grade students and are organized by topic and standard. And Android users--your version will be coming out this fall.
