If you teach Louisiana Social Studies as I have for the past 27 years, you are looking for something interesting to get your students "hooked into history". When I started teaching there was 'no way I would do this' for fear of losing control of 'my' class.
Later, as I became more confident in my teaching I began doing this assignment with just ONE set each hour, Later, as my confidence increased and I began to have more control and I became very good at multitasking, I began to do this activity with three or four sets per hour.
As of late I was looking for a way to get my students active in the beginning of the year and this might be just what you're looking for! I use this activity during the first week of school so I can informally assess my students' background knowledge and deductive reasoning in regard to my beloved Louisiana history.
As I teach 8th grade Louisiana History, the way I go about this activity is by printing the pictures and dates on different colored sheets of cardstock, cutting the dates and pictures, and placing one set of dates and pictures in the same envelope. (I use pink, yellow, lavender, and light blue cardstock.)
It all depends on you school district, as to how you go about printing and laminating. But if you can do it right you will not have to do it over and over and over each year.
