Chromebook School: Dragonbox Math

I’m already adding to the Chromebook School: Math post–this time, with a great discovery via The Homeschool Scientist, who recommends their app–which purports to teach algebra to kids from age 5 on. In addition to “Algebra 5+”, they have a number of other apps for building number sense, or learning geometry and going to higher-level algebra. (Later, after having my daughter play the first few levels: great mechanics, horrid aesthetics! Use at your own preference.)
