Math Manipulatives

These are all located in Amy Szczepanski's office (A203).

The Math Department owns the following manipulatives:

• A book filled with ideas on how to use manipulatives.
• Semi-reflective plates called Miras. Used for geometry activities, especially with symmetry.
• Lenart Sphere
• Base 10 blocks and other base 10 items.
• Cuisinaire rods. Colored plastic rods of assorted lengths.
• Tangrams.
• Small shapes of assorted sizes, colors, and materials.
• Two color counters (small plastic disks with a different color on each side).
• Geoboards. Plastic arrays of pegs. Use rubberbands to generate polygons whose vertices are lattice points.
• Large transparent plastic cube made to resemble a die.
• Spinners of assorted configurations.
• Wooden shapes. Assorted polyhedra, cylinders, and cones.
• Blackboard compass.

Amy Szczepanski owns (and will lend out):

• Innertube with a large hole.
• Planimeter (machine that does Green's Theorem).
• Regular dice.
• Balloons.
• Small mirror.
• String.
• Pine cone (for Fibonacci numbers).
• Wax paper (for making conic sections).
• Proportional sizing wheel (Vaguely like a round, single-purpose slide rule, it's what graphic designers used to scale images before computers did it for them.).
• Ruler which measures picas and points.
• Small spindles (solids of rotation).
• A large washer.
• Shape tracers.
• Crocheted negatively curved surfaces.
• Quilted Mobius band.
