To assist my students with their research of the 20th Century, I made simple charts for them to complete. To prevent distractions, I included four links to specific sites about each decade. I've included the direction sheet that I'm giving to the students, but that's something that you'll want to adapt for your classroom. I'm trying something new and giving mural.ly a shot.
With ten decades to cover, I'll probably have them work in teams, but that's not mentioned in the directions, so you may want to add that to your own directions.
It's nothing fancy, but my students need a little something to keep them focused. I hope it works for you.
