Friday, we dove into a modified version of Christopher Danielson’s hexagon activity as partially described in my previous post. Instead of coming up with classifications for each individual shape, I asked students to group the shapes. Not a lot for them to go on. Here’s what I saw…
Types of Groupings
- Favorite Numbers
- These pieces fit like a puzzle
- They’re long and skinny
- They look the same
Not a lot of math vocabulary and it was pulling teeth in response to my guided questions trying to elucidate SOMEthing a little more precise.
Number of Groupings
- Just enough so that each hexagon is in one group.
- Until I asked them to mix the hexagons up again and make new groups
This number of groupings makes me really anxious for quadrilaterals. I know students struggle with the idea that a shape can be more than one classification. Any tips or suggestions?
ALSO this makes me realize that I haven’t done enough work to foster group talks in my classroom so far. I’m looking at blog posts like these to help me. Any others you would suggest?
