Footballs, diamonds, fish tails, and a military building. Are they alike? They are all based on two-dimensional shapes! Songs, videos, glue, and pasta will help you learn about some more flat shapes!
There are so many more shapes to explore!
You already learned about squares, circles, triangles, and rectangles! Let's put your skills to the test with more challenging shapes.
In this lesson, you will learn about ovals, rhombuses, trapezoids, and pentagons.

The first shape you will learn about in this lesson is an oval. Click on the blue icon below to learn how to pronounce the word "oval".
Look at the ovals below. Don't they look like circles? What do you notice that is different about them?
An oval looks similar to a squished circle. It's not perfectly round like a circle.

Take your finger and trace an oval in the sky.

The next shape you will learn about in this lesson is a rhombus, that can also be called a diamond.
Learn to pronounce the word "rhombus" with the blue icon below.
A rhombus can look similar to a square or rectangle turned on angle. Look at some of the rhombuses below.
If you said four, excellent job!
Don't forget, rhombuses are two-dimensional shapes. They are flat just like squares, circles, triangles, rectangles, and ovals.

Another important two-dimensional shape is a trapezoid.
Learn to pronounce the word trapezoid below.
Count the sides and tell an adult your answer.
Great job!
A trapezoid is similar to a rectangle.
Fantastic! Trapezoids have four sides like a rectangle, but two of the sides tilt inward and are not parallel.
