Class notes for naming shapes
Square- a square has four sides and it is flat. It is also 2D and has length and width
Triangle- a triangle is called a triangle because tri means three. A triangle has three points. It is
also flat and has the dimensions of length and width
Circle- a circle is flat and round. It is 2D and has two dimensions. However these dimensions are
different from other 2D shapes because they are called diameter which is how big the circle is
across and circumference which is how big a circle is around its edges. *** Do not worry about
learning these terms yet because you will learn them later on when you get in a higher grade
level. All I want to do is introduce you to the words and make sure that you have heard them.
Pyramid- A pyramid is like a triangle only it is 3D. It has three dimensions such as length, width,
Cube- A cube is like a square but it has three dimensions. It is not flat; it has length, width, and
Sphere- A sphere is like circles accept it is three dimensional. Think of a bouncy ball. A sphere
has a circumference, height, and width.
Length- how long something is
Width- how wide something is
Height- how tall something is
