This is a great way to spice up your centers (math, literacy or other). Rather than the traditional blue group/orange group, give your center groups some new names to identify with. The names with their corresponding cards and graphics included are:
Barrel of Monkeys
The cards have a place to write the names of all students in that group, as well as a place to write their weekly schedule.
This will probably work best if you laminate the cards, then write on them with dry erase markers as things change. Enjoy!
