The chapter Shapes and Angles introduces students to the fundamental concepts of geometry, focusing on how angles define the shape and properties of polygons. Through engaging activities, students learn to identify, measure, and compare angles using tools like protractors. They explore the creation of various shapes using matchsticks, understand the significance of angles in everyday objects, and recognize angles in natural settings. Real-life applications, such as the effect of angle inclines on speed, help solidify their understanding. This chapter builds a strong foundation in geometric principles, enhancing students’ problem-solving skills and making geometry both fun and practical.

**Shapes and Angles**

Through various activities and real-life examples, we can learn to identify, compare, and measure Shapes and Angles, providing them with a solid foundation in geometric concepts.

**Understanding Angles**

Angles are a fundamental part of geometry. An angle is formed when two lines meet at a point. The size of the angle influences the shape and properties of polygons.

We can learn to recognize different types of angles and understand their significance in defining shapes.

**Exploring Shapes with Matchsticks**

One of the engaging activities in this chapter of “Shapes and Angles” involves creating shapes using matchsticks.

By manipulating the angles between the matchsticks, we can form various shapes, illustrating how angles play a crucial role in geometry.

**Activities and Learning Outcomes**

**Rohini and Mohini’s Shape Challenge**

Through the story of Rohini and Mohini, we explore how to replicate shapes by understanding their properties. This challenge emphasizes the importance of angles and sides in defining shapes, helping us to develop our problem-solving skills and geometric understanding.

**Identifying and Coloring Angles**

This activity from the chapter Shapes and Angles makes us learn to identify angles in different shapes by marking and coloring them. This activity enhances their ability to recognize and compare angles, reinforcing their understanding of geometric properties.

**Identifying the Largest Angle**

**Matchstick Puzzles**

We can use different numbers of matchsticks to create different shapes.

For example, we used 8 matchsticks to create a fish-like shape and used 10 matchsticks to create the shape of a house as shown in the picture.

**Angel Tester**

Angle Tester is a tool to measure Angles and is also called a Divider.

**Activity**: Make Angle Tester

Let’s learn how to make an Angle Tester.

- Cut two strips from a cardboard sheet.
- Fix them with a drawing pin or such that both the strips can move around easily.

We can use it to measure the angles.

**Now observe this picture, it showcases various angles**.

We find

- Right angle
- Angles more than a right angle
- Angles are less than right angle.

We can also find different kinds of angles.

- Right Angle
- Acute Angle
- Obtuse Angle

**Activity – Angles with your body**

**Angles in Nature**

As mentioned in the chapter Shapes and Angles, We can see different angles in nature, such as the beak angles of birds or the angles between branches.

This activity encourages students to apply their geometric knowledge to the world around them, enhancing their observational skills and appreciation for geometry in natural settings.

**Angles in Name**

Further in the chapter Shapes and Angles, we’ll also understand how we can identify angles in names. Let’s see the example given below.

In this name, there are 11 right angles and there are also 10 angles less than a right angle.

**Activity**:

Write names using straight lines and count the types of angles in the letters.

**Task**:

- Count the number of right angles.
- Count the number of angles greater than and less than a right angle.

**Learning Outcome**: We can explore how angles are present in everyday writing and objects.

**Activity:**

- Put 10 Math-Magic books on top of each other. Keep one book slanting to make a slide.
- Now do this with six books. h Roll a ball from the top.

From which slide does the ball roll down faster? Which slide has the smaller angle?

**To learn the comparison of angles by observing the position of the slide in the park**.

#### There are two slides in the park.

- Which slide has a large angle?
- According to the angle measurement, which slides do you think are safer for the little boy?

**Changing Shapes**

Further in the chapter Shapes and Angles, we’ll learn the process of changing shapes. Let’s take an example- We can create 4, 5, and 6-sided shapes by using tube pieces and matchsticks.

We can find out how many angles are there in each of the shapes.

**One more activity to find out the Shapes in Towers**

**Angle and Time**

There are many times in a day when the hands of a clock make different angles as shown in the picture.

**Degree Clock**

**Activity: **Making a Degree Clock

- Cut a circle out of paper.
- Fold into half.
- Fold into once again Into a quarter.
- Fold into once more.
- Open the paper. You will see lines.
- Now mark the angles of 0°, 45°, 60° and 180° degree as shown.
- Paste it on an old card.
- From the center draw one card.
- Make a red hand with thick paper and fix it to the center with a drawing pin, so that it is free to move.

We can use it to measure the degree of the angles.

In the same way, we can create Angles in Paper Aeroplane.

As we have shown the angles activity with Body parts, here is one more activity to show the angles with Yoga.

**The D Game**

Using a protractor, we can measure angles of different degrees. We can turn this activity into a fun game by playing with friends. For example, we can create an angle and ask our friends to guess its measure.

**Conclusion**

In conclusion, CBSE Class 5th Math, Chapter 2 – Shapes and Angles is a fundamental step toward understanding the world of geometry. By learning how angles shape polygons and recognizing their presence in everyday life, students develop a keen sense of spatial awareness. The various activities, such as using matchsticks to form shapes and measuring angles in natural settings, ensure that students grasp the concepts in a fun and engaging way.

This chapter, Shapes, and Angles, not only strengthens their mathematical foundation but also fosters curiosity about the geometry that surrounds us. As they master these concepts, students will be well-prepared for future mathematical challenges, making Chapter 2 – Shapes and Angles an essential part of their learning journey.
