You may use these menus however you like, but this is how I do it...
My students spend one day a week rotating through centers with their partner. The other days they are in their seats working waiting for their group to be called back to small group. I use these menus for discussion starters and formative assessments. Students complete these mostly independently and come to small group to discuss and to deepen their understanding This is their daily independent work after whole group lessons.
Like I said you may use them however you like, but PLEASE do not use them as busy work!
Depending on the skill of the week I include a graphic organizer or two to reinforce the concept.
