Welcome to army life!
This project gives a real life example for 24 hour time, something my students were struggling with. Students can work at their own pace through the project giving you plenty of opportunities to run support and extension groups. I also created my own videos using the App Explain Everything, I uploaded these to Vimeo which allowed me to provided targeted instruction to all of my students not making them sit through things they already knew and providing extra support for those kids who need it.
The project includes
converting between 12 and 24 hour time
calculating elapsed time
