Board Problems
We discussed "perfect looking" hexagons vs not for the vocab word of regular.
I asked them to draw diagonals and then had them define a diagonal.
We noticed the number of triangles inside the polygon and saw the pattern to make the formula.
I finished with asking them to draw and name all the polygons they knew. More great discussions...
Is a circle a polygon? I had not defined it, so I asked them to and they got all 3 characteristics.
What about a square, rectangle, rhombus, and kite - are they polygons?
One group came up with dodecagon but asked about how many sides a dodecahedron had so we discussed 2D vs 3D.
Edited to add one girl thought one of them was a "rhododendron" Too cute.
Then, we came back to our desks for a Desmos card sort to clarify more vocabulary. Which led to more discussion. I love when the card sorts ask for more than one way to sort things. Genius!
Finally, a practice worksheet to put it all together.
I had the following meme on my daily agenda. I guess this has turned into my High5. Kids look forward to coming to class to see the meme and then it takes a minute but there is usually a smile or a laugh. A great way to start each class.
Today's - being from Boston - we always sing "Sweet Caroline" at the Red Sox games:
It was a nice lesson for a Monday. Thought I would share.
