Today, we're going to dive deeper into the world of mathematics and focus on a topic that will help you understand shapes, lines, and measurements better - angles! We'll learn what angles are, how to measure them, and how they apply in our day-to-day lives.

Let's start the lesson with a fun warm-up activity! We'll play a game called "Name That Angle." I'll show you a few pictures, and you'll have to identify what type of angle it is. Don't worry; it's going to be easy!

Now, let's come to the main topic of our lesson - angles. An angle is a measure of the separation between two lines, rays, or planes. In simpler terms, it refers to the amount of turn between two straight lines.

We can measure angles in degrees. A full circle has 360 degrees, and we measure other angles with reference to it. An angle that measures less than 90 degrees is called an acute angle, while an angle that measures more than 90 degrees but less than 180 degrees is called an obtuse angle.

There are many types of angles that we'll study today, such as:

- Acute angles
- Obtuse angles
- Right angles
- Straight angles

That's all for today's lesson. I hope you enjoyed learning about angles and their types. Remember to stay curious and always keep an eye out for the different angles around you - you'll be surprised at how much they're used in our everyday lives!
