Love this idea! (I often see similar activities for math, but this is the first time I've seen this activity used within a literacy lesson.) This could be a great exit ticket idea for the topic they just learned about.
GREAT IDEA : Collaborative posters : Each student has one colored marker. Students are not allowed to swap colors with other students. Teacher can assess at a glance who contributed what to the activity.
This would be a very fun activity the first week of school! Teacher says a statement (ex. Switch sides if you like hot dogs more than pizza.) and the students either stay or move. The kids could also talk about why they did/didn't move.
We all dread it, but what a fun way to get the rest of the school involved and build up the kids! Great idea to surprise students with on those dreaded standardized testing days. Or do this for the first day of school, last day, special events, etc!
