Geometry Observations

For maths we had a visitor from Miss. Stones university come observe our maths lesson. Today for maths we were learning about geometry. Maths was very interesting and fun!. This is the maths problem we were given.

Carries Cubes
Walt: identify classes of two- and three-dimensional shapes by their geometric properties.

Carrie has glued some cubes together to make a large solid cube with nine small cubes showing on a face.
She paints the large cube red.

How many of the original small cubes have:
  1. three faces painted red
8 cubes

  1. two faces painted red

12 cubes
  1. one face painted red

6 cubes
  1. no faces painted red : 1 cube

I felt the problem was a lot about logic too. Interesting to see some of the students using a model but you Miss Luisa quickly figured you would need 27 blocks which was great :)
