Brand new from the team behind Oh No Fractions, Curious Ruler is fantastic app that helps students explore measurement. I’ve shared some of my favorite virtual tools for the math classroom and this one definitely belongs on the list. It asks you to choose from a selection of common objects to use as a reference tool for measuring other objects. You can see in this picture how I used my iPhone as a reference to measure the length of my iPad case. This very cool app is free for a limited time, so download it today!
