Sorting and Categorizing 2-D and 3-D shapes

Over the last week, we have been extending our review of 2-D shapes to include 3-D shapes. We have discovered the attributes that help us to differentiate between 2-D shapes such as number of sides, vertices, size, and colour. We then discovered ways to categorize 3-D shapes. Several students wanted to extend their learning by knowing how they could put objects together that are different but also have 2 or 3 characteristics that they share. It was through this request that we discovered how handy a Venn Diagram can be.

Their job was to work together as a class and decide where they feel the photographs fit in on our timeline.

" I knew by looking at the people's old fashioned clothes" "I knew that the Calgary tower was built for Canada's birthday but not it's birthday that long ago". "Calgary did not always have the stampeded so that must have been after Fort Calgary was built" "When we watched the video I learned that they only
