Analyze and Compare Two- and Three-dimensional Shapes: CCSS.Math.Content.K.G.B.4

Both of these shapes are the same size and the same color. The difference is the type of shape.

We have a pentagon, a five-sided shape, and a hexagon, a four-sided shape.

The difference between these two shapes are the number of side lengths they each have.

The triangle has three sides and the rectangle has four sides. They are both two-dimensional shapes because they are both flat shapes, and they are both red shapes.

Both of these shapes have four sides.

Both of these shapes are two-dimensional because they are both flat shapes. They are also the same color.

However, the circle is a round shape and the triangle is made up of three, straight lines.

Both of these shapes are three-dimensional, or solid, shapes.

Both of these shapes have four sides.

Both of these shapes are the same height and they are two-dimensional shapes, because they are flat. The difference between them are the number of sides they each have.

The triangle has three sides and the rectangle has four sides.

Both of these shapes have the same number of sides.

The shape on the left is a solid shape, or a three-dimensional shape. The shape on the left is a flat shape, or two-dimensional shape.

Both of these shapes have four sides.
