Jordan Shapiro writes that;

“On average, it took 41 minutes and 44 seconds for students to master Algebra skills during the Washington State Algebra Challenge using the DragonBox App.

The Challenge, co-sponsored by Washington University’s Center for Game Science and the Technology Alliance included 4,192 K-12 students. Together, they solved 390,935 equations over the course of 5 days in early June. According to the Challenge’s calculations, that’s 6 months, 28 days, and 2 hours worth of algebra work.

What’s even more impressive, “of those students who played at least 1.5 hours, 92.9% achieved mastery. Of those students who played at least 1 hour, 83.8% achieved mastery. Of those students who played at least 45 minutes, 73.4% achieved mastery.”
