conjuguemos.com : Some students won’t need to use this website as they have already mastered this material.
spanishspanish.com : Pretty much every student should spend some time on this website as they learn how to spell numbers and practice some larger numbers.
duolingo.com : Some students will never get to this website, because I told them that they should master the other material first. Duolingo has enough material to keep them busy for weeks, so no one should run out of stuff to do.
