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.

Can you name any of the shapes below? What do you notice about the shapes below? Tell a parent or guardian what you know about the shapes below:


In the previous Related Lesson, found in the right-hand sidebar, you learned about squares, triangles, rectangles, and circles.

Quickly draw a picture of each of the shapes you learned and show an adult.

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. An oval is a two-dimensional shape. Remember, two-dimensional is just another way of saying flat. An oval is a flat shape. Take your finger and trace an oval in the sky. Was your oval big or small?


Watch the Learn Shape Oval video | Math video for kids (Turtle Diary) video below to learn more about ovals:


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. How many sides do they have? 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. Trace a small rhombus in the sky with your finger.


Listen and sing along to the Rhombus Song Video by Have Fun Teaching:


Another important two-dimensional shape is a trapezoid. Learn to pronounce the word trapezoid below.

What do you notice about the trapezoids below? Count the sides and tell an adult your answer. Did you count four sides? Great job!

A trapezoid is similar to a rectangle. What do you notice is different? Tell a parent or teacher. Did you say that two of the sides tilt inward? Fantastic! Trapezoids have four sides like a rectangle, but two of the sides tilt inward and are not parellel. Use your finger to trace a big trapezoid in the sky.


Watch this The Book of Shapes -Trapezoids and Rectangles, Luli TV (Luli TV – Videos for your baby) video from the 2:30 timestamp to learn more about trapezoids:


The last two-dimensional shape you will learn about in this lesson is a pentagon. Learn to pronounce the word pentagon below.

A pentagon has five sides. What do you notice about the pentagons below? How many sides does a pentagon have? Tell an adult. Fantastic! A pentagon has five sides. Trace a large pentagon in the sky with your finger to help you remember what a pentagon looks like.


Try drawing a pentagon by watching the How to Draw a Pentagon | Learn Shapes | How to draw Shapes for kids video from Kids Hub below:


You did a wonderful job learning all of these new shapes!

Before moving on to the Got It? section, tell an adult the names of all the shapes you have learned in this lesson.
