Fun With Playdoh In Mrs. Hopkins’ Math Class

Mrs. Hopkins 7th grade math class explored cross sections of solids using playdoh.  The students had to construct solids such as cubes, cones, square pyramids, and triangular prisms using playdoh.   Then the students sliced the solid using fishing line in various ways to determine the cross section, the two-dimensional shape, that was formed.  Students also determined what shape(s) could or could not be formed by slicing a solid.
