How to Measure in 2D and 3D in Google Earth

More than a decade ago Tom Barrett's Maths Maps inspired me to start thinking about how Google Maps and Google Earth can be used in mathematics lessons. Since then I've developed some of my own math activities that incorporate measuring in Google Earth. If you'd like to create your own math lessons that incorporate measuring in Google Earth, watch my new video about how to measure in 2D and 3D in Google Earth.

How to Create Custom Google Slides Guidelines

One of the many "hidden" features of Google Slides is found in the view menu. It's there that you'll find the option to turn on and turn off gridlines (Google calls them guides). Not only can you turn on or turn off the guidelines, you can also add additional lines and create custom spacing for the guidelines that you add to your slides. Watch my video that is embedded below to learn how to add custom guidelines to your Google Slides and why you might want to do that.
