This site can be a fun way to transition between topics, as a review game for a assessment or a "get to know you" activity. Create questions or use some from the Kahoot library to game where students respond with their electronic devices (phones, tablets, computers, etc). It is fun, fast and informative as long as you have an internet connection.
INFOhio is a great resource that can help with research papers, biographies, and additional study materials. Everything on this site is free to SWCSD teachers and students as long as they are connected to a school server. Outside of school a password is needed and if you need it contact me (dkh0427@swcsd.us). Ancestry.com is also on this site in a limited function.
Make the videos you create or find online come alive as lessons or quizzes using EdPuzzle. This program takes a video and allows you to cut out what you don't want, add stopping points, add questions, and records it how those students did individually and as a group on those questions. Furthermore, it connects with your G-Suite account making uploading students a breeze.
