1) Free Math Lessons, Videos, & Practice Quizzes
As always, my Pre-Algebra, Algebra 1, Algebra 2, and Geometry online math lessons are all free. The lessons include practice quizzes with instant feedback and helpful videos with examples. Many of the lessons have printable study guides that would be helpful for students going through the lesson on their own at home (grab a free study guide).
2) Self-Checking Google Activities
It's easy to make Google quizzes that are graded automatically. They're a great way to assess learning and give feedback while teaching remotely. You can quickly learn how to make your own Google quizzes or try out this free activity for Google drive.
4) Use Zoom for Online Meetings
Don't have access to Google Hangouts? Zoom is another great option to host an online meeting with your students. Their free plan allows you to have up to 100 people in a meeting at once. Zoom can also record your meetings so you can easily upload the video online for students to access.
5) Kahoot & Quizizz
Have you tried making Kahoots? Kahoot is currently offering free premium features for schools facing closures. Students love being able to play live against each other or you can have them complete the quizzes at their own pace. You can also search Quizizz for free gamified quizzes or create your own.
6) Additional Online Tools
Many companies are starting to offer discounted or free subscriptions for schools affected by the virus. Stay up to date with more useful online tools by following this Wakelet by Erin Flanagan.
