Register at International Dot Day, to join in on all the fun! Once you have registered your class, make sure to download the free handbook on how to celebrate Dot Day with your class. There are lots of great ideas in the handbook.
Something that I think would be a lot of fun to do in the classroom is to download the colAR App (for both iOS and Android). Then, download the Free Mix Pack that has the colAR Dot Day coloring page. Have students decorate or color that coloring page. Once they are finished, open up the colAR app that you downloaded and show on the screen. You can show it as a 3D image, or flat image that turns in a circle. Below is the one that I did.
