Ginger Snaps Treats for Teachers ~ a landform flip book that starts out as individual forms but then when it comes together it builds an entire scene of a physical environment incorporating all different landforms.
Another way for students for grade students to learn about landforms! in partners, or in groups, students are given a landform and they write about what it is. Then we can hang it up so all the class can see each landform.
