Math Kit for Students at Home
This toolkit of resources will help you find great math activities for students who may be learning remotely. The first few resources focus on grades K-5, one for each grade level. Following those are links to more resources, again with specific grades identified. Finally, some math sheets are included that can be printed out by students or added to other collections you might be creating. A number of resources support both English and Spanish language students.
Many of the resources are publicly available Google docs which you can save and organize in your Drive. Alternatively, you can make a copy of these files and then add the share link to a collection you are creating using the "Add a Link" feature when building a Collection (but don't forget to set the sharing settings on your Google doc so students can access your files).
