From content consumption to content creation, there are many ways to use mobile devices with students. They can create how-to videos for authentic audiences, explain their thinking through screencasting, or use scannable technology in the math classroom, for example. Mobile devices can also be used to help students practice foundational math skills and build their math fluency. You might decide to use an app on this list as part of an intervention plan or add it to a newsletter for families.
The list is heavier on the apps than on websites, which is very helpful if you are an iPad or Android district. If you are a Chromebook district, you may want to investigate how soon Android apps will be coming to your Chromebooks.
