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 oks 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.
