Shapes and Attributes

In math class, we have been working with 2-dimensional shapes and attributes.

Here, several of us are sorting buttons by attributes including shape, color, size, and number of holes.

We tried the Woozle Game, which was also sent home as homework. This was a bigger challenge than it looks! Most students could sort into two opposite categories:

straight sides and curvy sides

blue or orange

two dots or one dot

It was much more challenging to find a way to sort so that some cards would end up in the middle because they belong in both circles.

straight sides or hairy -- If they have straight sides AND hair, they go in the middle!
If they have neither, they go on the outside.

We also used real geoboards and a geoboard app to make different shapes.
