There are so many websites available for your students to use as math practice, either in class or at home. Mathgames.com is a super basic website, but it has just about every category you could possibly think of to introduce.
This specific video was a tutorial to help students understand how to get to the website on their own, and then directs them to a simple game of “adding by 10s.”
I would definitely use a website like this in my classroom if we are focusing on the basics of adding, subtracting, etc. where students need a lot of repetition and practice to understand. Changing between paper practice and screen practice could be really beneficial.
