# Lesson 1- What makes a shape? - Lesson for Grade 1, Chapter - 2D and 3D Shapes

In Lesson 1, titled "What Makes a Shape?", first-grade students dive into the fascinating world of geometry, focusing on the properties and characteristics that define 2D and 3D shapes. Through engaging activities, students will embark on a journey with Toby to learn about basic shapes, understanding the foundational elements that make each shape unique. This exploration is vital as it lays the groundwork for recognizing and distinguishing between various shapes in their environment.

The lesson incorporates practical exercises such as "Two-Dimensional Shapes: Vertices Printable" and "Plane Geometry: Sides Printable," where students will identify and count vertices and sides of different shapes. These activities are designed to enhance their observational skills and understanding of geometric properties, crucial for their mathematical development.

Furthermore, the "Twin Shapes Dot-to-Dot Worksheet" adds a fun twist to learning, allowing students to connect dots and discover shapes, reinforcing their knowledge through visualization and practice.

Understanding shapes is fundamental, not just in mathematics but in daily life. It aids in developing spatial awareness, critical thinking, and problem-solving skills. As students grasp these basic concepts, they build a strong foundation for more complex topics in geometry and beyond, fostering a lifelong appreciation and curiosity for the world around them.

• ### Activity 2 / 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 3 / 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!
