I am thinking of this next year with 2 R level, 1 D level, 1 UG and 2 LG. What I was thinking is to read SOTW aloud to D on down. Then the UG/LG and I would do map, narrations and extra reading aloud together.
The D level would go on to read their encyclopedia and make notes per WTM. They woud then be on their own to read additional sources and outline. I think at first you would have to sit and help them find additonal sources and outline, but as time went on they would be able to do this independently.
I think a group discussion at the end of the week with D on down could work, Some of the info might be over the UG/LG heads but at that age it's all about exposure anyways.
Since you have three in the same level, maybe do the reading outloud together and then they can do their independent work at different times during the day, While student 1 is outlining, student 2 is doing his map or additonal reading etc. Think this would work?
My R level would do their history reading/outlining/map and research on their own. We could go over their context pages during our disucssion times. I hope to read through the GB together, discussing them as we go.
I am on the fence on how well this would actually work here. I will probably chicken out and stick with TOG for the hand holding :D
