Rock Types Concept Maps
Teacher instructions:
Run the concept map pieces off on colored paper. It
is best to run the 3 different sets of pieces on 3
different colors of paper. Run the concept map
outlines on white paper. Run a regular white paper
copy of each concept map outline for each student.
Let students work in small groups using their books
or other sources to place the pieces in the correct
spot on the concept map outline. When they have
everything in place, they call the teacher to check
their work. Teacher ok’s or gives guidance into
which area(s) need to be re-worked. When all is
correct, teacher gives each student in group a blank
copy of the outline to write in the answers (shown on
pieces). Students keep their copy of the concept
map for reference, and begin the next concept map
with a new set of pieces and outline.
