I teach at a high school in SLC, Utah. My class is very diverse in that we have multiple languages in the class, English is not the native language of 95% of my students, I have pretty close to 50/50 boy, girl ratio and the class is a good representation of students from the entire school ranging from grades 9-12. Our class period is 90 minutes every other day.
I use journals in class where the students write down their answers to many of the prompts so that they can think about their answers before sharing them with the class, take a minute to think before they say anything, or as a reference to look at later when they forget something we've talked about in class.
I took some time to prep for this activity -
I had the items already cut out, table boxes ready with glue and markers, as well as, posters for them to categorize their picture items.
The students had fun debating what picture fit on which side and then comparing them later with other groups.
I don't have much room in my lab to spread out, so we worked on the floor, moved monitors and found wall space to make the posters.
