# Counting Sides/ Angles 2D - Lesson for Grade 2, Chapter - Shapes and their Characteristics

In the "Counting Sides/Angles in 2D" lesson, part of the Geometry unit focusing on Shapes and their Characteristics, second-grade students will embark on an engaging journey to understand the basics of two-dimensional shapes. By participating in activities such as "What Shape Am I?", "Plane Geometry: Sides Printable", "Shape Maze Worksheet", "Two–Dimensional Shapes: Vertices Printable", and "Counting Sides and Angles", students will gain a hands-on understanding of how to identify and count the sides and angles of various 2D shapes.

This lesson is fundamental for several reasons. Firstly, it lays the groundwork for geometric understanding, a key component of mathematical literacy. By learning to recognize and differentiate between shapes based on their sides and angles, students develop spatial awareness and critical thinking skills. Secondly, this knowledge serves as a building block for more complex mathematical concepts they will encounter in higher grades, such as area, perimeter, and volume calculations. Additionally, understanding shapes and their properties is not only essential in mathematics but also in everyday life, aiding in the recognition of patterns, symbols, and structures in the world around them. Through this lesson, students will cultivate an appreciation for geometry's role in both academics and real-life applications.

• ### Activity 2 / Plane Geometry: Sides Printable

Your child has spent an entire toddlerhood learning simple shapes, but now he’s learning about polygons, and some shapes can get tricky. Supplement your child’s learning by teaching about sides and how to count them with this worksheet that focuses on plane geometry sides for 1st grade!
• Count sides to identify advanced shapes
• Recognize and differentiate between polygons
• Build a foundation for future learning in geometry and math
Learning geometry helps kids to understand how math surrounds them in the everyday world. Jumpstart their geometrical awareness by teaching about sides with this fun and colorful worksheet!

• ### Activity 3 / Shape Maze Worksheet

How well does your child know his or her geometry vocabulary?
This colorful shapes maze printable worksheet will put your child’s math vocabulary to the test, challenging your child with identifying a shape based on vertices alone! Help your child to think of a shape that has 8 vertices to navigate through the maze to find the correct answer.

• ### Activity 4 / Two–Dimensional Shapes: Vertices Printable

Shapes, lines, and corners are everywhere! Math is all around us, which is why kids should learn geometry early on. Extend your child’s knowledge and vocabulary in geometry with this colorful worksheet that focuses on two dimensional shapes: vertices.
This worksheet is great because it:
• Clearly defines vertices, and breaks it down into an easily understandable idea
• Provides practice with counting vertices with different shapes
When difficult vocabulary is broken down into something your child can relate to, the word is easy to understand. Practice vertices and enhance your child’s learning with this vibrant geometry worksheet!

• ### Activity 5 / Counting Sides and Angles - Quiz

This quiz assesses students’ ability to identify the amount of sides and angles different shapes have.
