Creating 3-D Shapes

My students explored spaces in 2-d before we moved to 3-D ones.

 Then they were off and running!  They made tetrahedrons, pyramids the square bases and triangular bases and pentagons.  Labeling each shape they were eager to make more complicated shapes.  Gum drops and marshmallows take a little more patience to assemble but it the individual pieces are make and let sit out for  day, they harden up and make the structure sturdier.

Gum drops work well too!
