You are likely already plenty familiar with Khan Academy as it has already been used by our math department to provide additional tutorials for students. Along with other powerful tutorial sites, a link to this completely free resource can also be added to the sidebar of class Schoology pages or wherever math homework is assigned. While the lessons are not specifically Singapore aligned in their explanations, for our older students it allows for tutorials as an additional accompaniment to their learning.
***Side Idea*** Once students get some experience with evaluating what makes a successful video tutorial, there are a number of platforms featured on this site that we can use to curate and showcase our own student lessons.
Code.org is a free online platform that teaches students of all ages how to code at their own comfort level. Younger students can progress through different challenges using block-based coding, similar to what they will use when working with Scratch Jr. The early lessons also let them click on the speaker icon to hear directions rather than rely on being able to read them, should they still be an emergent reader. Our oldest students will also be plenty challenged as they are given personalized lessons that suit their level of programming experience.
