Somebody sent me an email earlier this week asking for web tools to create and draw on maps. Below are two of the tools that I know of but you can also check this collection of map tools I have published a few months ago it also features some other good applications to use while working on maps with your students.
1- Scribble maps
Watch the video below to learn how to use Scribble maps
Quickmaps allows users to draw a quick map. It is very easy to use but it requires a sign up which is completely free. You can create maps using different tools and once finished you can then get a link to embed it in your class website or share it with others via email.
