Nets and Decorations

For the past two weeks, we have been continuing to explore 3D objects, and more specifically their nets.  During the first lesson, we played with the nets of a cube.  The kids were given pictures of hexominoes (arrangements of 6 squares) and tasked with determining which of them could be folded into a cube.  To help them with this, they were given Magformer squares.  They would first make the hexomino using the Magformers, and then see if theycould fold it into a cube.

    We did a series of origami activities, including making platonic solids, that the kids really enjoyed.
    Another activity that was mostly artistic was just playing with drafting tools (compass, t-square, some standard triangle templates) and colored pencils.

    My personal mathematical tastes tend more toward algebra and number theory, so I have to consciously remind myself to look out for tactile and visual mathematics and activities. I will be borrowing your hexomino activity soon (probably using polydrons)!
