There is so much content to cover in 5th grade History, that we made a timeline to help us keep it all straight. I made the outline of the boxes, and after reading about each event, groups got together and filled in its spot on the timeline. This was up in our classroom, but we had to move it to the hall because of state testing. It was great to have this visual in the room for students to reference so they could see where each event fit in on the big picture!
Then to review before the test we gave each student an event off the timeline and they had to form a human timeline of the events, working together. I like how it made them actually think about the cause and effect of it all. Now...hopefully they remember it all on the test!
