Make your own 2D and 3D Shape making Center

Constructing 2D shapes in math
Make your own 2D and 3D Shape making center by using simple items that you can get at any craft store or at Amazon. I love to find awesome classroom decor ideas. As an Amazon affiliate, I may earn a commision for purchases using my links. Learn more.

Get a load of this: pipe cleaners (#add) and straws. That's all you need to make triangles, quadrilaterals and polygons. I did this back when I had my fifth grade class. There are so many rules in geometry that we can take for granted. For instance, I asked them to define a triangle for me (after they joined three straws together). They said 'a plane shape with 3 straight sides'. So using that definition, I gave them a non-example:

An open plane shape with three straight sides. Is it a triangle? No. So this means that the three angles must be important to mention. In fact they were important enough to give the triangle its name.

We explored every plane shape we could make. And it challenged the students to pay attention to detail when generating their own definitions. It was a fun experience. Of course, you can try it with your class but you do not have to stick to straws only. Craft shops sell the sticks that you use to make mini flags, not the dowel sticks but hollow plastic ones. There are also the sticks to which we attach balloons. They are more durable than straws, just use a pair of shears or a knife to cut it into shorter lengths and use even shorter lengths of pipe cleaners (chenille stems) to make the corners. By the way, they also interlock so that you can make cubes, cuboids, pyramids and prisms with them too.

You can also use craft sticks and add Velcro dots (#add) to the ends to make polygons.

About Me

My photo
As a Caribbean primary school teacher, I share my unique classroom with the world through this blog. Readers step into my class through the pictures, articles and classroom samples of games and lessons used in my class. I have been teaching since 2005 at the std. 4 primary level in Trinidad and Tobago. I am particularly interested in sharing my own personal lesson plans, tests and activities. Teachers need to share ideas and support each other because in doing so, we help to educate our students and develop ourselves as teachers. Technology is ever evolving and we as teachers should get on board with it, collaborate and keep up to date with this new age that we live in. Our students belong to this technological era and we must embrace opportunities to learn from each other in this global community. I also love to express my creativity in the classroom. I am a bit of a craftster . So I'm always cutting, gluing or making something... a game, a chart, a learning center, etc. So, teachers and parents, feel free to stop by and see what's new at Nyla's Crafty Teaching!
