One impressive thing about Math Learning Center, the publisher of Bridges in Mathematics, is their math apps. On their website, they offer ten (with one in beta) mobile apps for users to download and install. Not only are they helpful tools for math instruction and practice, Math Learning Center has developed these apps to be cross-platform - iOS, Chrome, Windows, and web-based. Equity and Access.
Not only are these cross-platform apps helpful tools for math instruction and practice, they are apps that can be used with any math curriculum!
