Building with Bendaroos and More (12-1 thru 12-7)

This week the Mathletes created two and three dimensional figures with Bendaroos (colored wax sticks) including: 2-dimensional - circles, square, equilateral triangle, isosceles triangle, right isosceles triangle, rhombus, pentagon, hexagon, trapezoid, parallelogram,  decagon, and septagon; 3-dimensional - prism, cone, cylinder, and pyramid. See the attached pdf file so your child can practice with these shapes.

These are many of the shapes builders and architects use to create the great buildings of the world.  The attached pdf includes six of my favorite buildings:

  • Empire State Building, New York (built in 1931 with 102 floors)

  • Petronas Towers in Kuala Lumpur, Malaysia (tallest twin towers in the world, built in 1998)

  • Eiffel Tower, Paris (built in 1889, largest building in Paris)

  • Sydney Opera House, New South Wales, Australia (built 1973)

  • Taj Mahal, India (built in 1653)

  • CCTV Headquarters, Beijing, China (built in 2004)

In class, the Mathletes built their versions of these and other structures with Bendaroos using the 2 and 3 dimensional shapes.


This week, I look forward to what your Mathletes can create on their own using building material from your home (popsicle sticks, straws with pipecleaners, Bendaroos, Legos, sticks from outside).  I instructed the children not to use a glue gun without the supervision of their parents.
