The fall air has finally blown in and I am loving it. We had a lot of fun this week learning about 2-D shapes. Your kiddos identified 2-D shapes by counting their sides and vertices. They really loved learning about the "special" shapes that we don't normally see and hear about. We learned about the septagon, octagon, nonagon, decagon, undecagon, and a dodecagon. Ask your student if they can remember how many sides and vertices these shapes has. We also composed and decomposed 2-D shapes. Compose and decompose are vocabulary words that we have used previously to describe adding and subtracting. I liked watching them make a visual connection with shapes. We put different shapes together and identified the new shape that we created. We also looked at how we could break up a shape into new smaller shapes. We will do more with this on Monday. Next week, we will be getting into 3-D shapes. The hardest part of 3-D shapes is identifying what shapes make up the 3-D shape. We will be creating 3-D shapes for them to take apart and put together. I encourage you to look at 3-D shapes at home and talk about what shapes create it. For example. a cereal box is a rectangular prism and is made up of 6 rectangles.
Here are a few technology tools that you can use at home to practice geometry:

I look forward to seeing everyone next week for parent conferences. Have a great weekend!
