Hang up anchor charts using a hook and ring system so you can keep several in one place at the same time students can remove and use as needed. Put clear packing tape along the top before you punch it and insert the rings.
Attach a small "metal book ring" through the hole and then attach a larger ring through that one. This way, the ring is going the same direction as the chart paper or poster and will sit in the groove properly.
Teaching My Friends!: Too Many Anchor Charts! Keeping Track of Anchor Charts: Take a picture, print it and file it in a binder before taking the poster off the wall. Teacher and students can refer to the binder even if the anchor chart isn't on the wall.
