Last week my blog explored number sense and how
it could be taught in a kindergarten classroom. Looking at the next generation
common core standards next up we are going to be looking into how to teach kindergartners Geometry.
I taught this to kindergartners last year for
the first time and I expected that since it was shapes that it would be easy
for them. I learned that this topic can be just as difficult as addition and
subtraction for a lot of students. I am glad the next gen common core standards
are going to address this in a way that I think will helps students grasp
concepts of 2d and 3d shapes. Here are the learning goals for the next gen
common core standards.
· Describe their physical world using geometric ideas (e.g., shape,
orientation, spatial relations) and appropriate vocabulary;
· Identify, name, and describe basic two-dimensional shapes, such
as squares, triangles, circles, rectangles, and hexagons, presented in a
variety of ways (e.g., with different sizes and orientations), as well as three-dimensional
shapes such as cubes, cones, cylinders, and spheres;
· Use basic shapes and spatial reasoning to model objects in their
everyday environment to create and compose more complex shapes; and explore* coins and begin identifying of pennies and dimes.
With these in mind my next question is how can
we teach this in class? More specifically, how can we teach this so that the
students are engaged and get the most from the lesson? Like any good teacher I
took to the internet to find the answer.
This site has a lot of good activities for kids.
All of which are centered around the use of manipulatives. It could be creating
a triangle out of Legos or making a square out of number cubes. The key piece
to this learning will be the hands-on experience. Once doing this we can work
on the objective of finding shapes in the physical world as the students will
already be familiar with the appropriate shapes.
Lastly, I would like to share a video that we
use in my classroom. This man Jack Hartmann (no relation) has so many great
videos dealing with shapes, numbers, letters and words. These have been extremely
effective in our classroom so maybe someone else could benefit from them.

Hi James, I am currently teaching my second graders the basics of geometry. We just learned about polygons and 3D shapes. I found this video really useful for teaching 3D shapes because I found that my students were struggling with the concepts of faces, edges, and corners. https://www.youtube.com/watch?v=3-QwWFkz5hw I checked the link that you posted about shape activities and I really loved the toothpick one. Vertices is a concept my kids were also struggling with and this activity really emphasizes it by having the kids build the polygons themselves with toothpicks and clay. Great resource- thanks!

DeleteHi James! I really liked that within your blog you raised some important questions and then reported back on answers that you found. I enjoyed the video! Thank you-Marlee
