# Distinguishing Attributes - Lesson for Grade 1, Chapter - Math in Shapes

In the "Distinguishing Attributes" lesson, part of the "Math in Shapes" chapter within the Geometry unit, first-grade students embark on an exciting journey to understand geometric concepts through engaging activities. This lesson is specifically designed to introduce young learners to the foundational elements of geometry by focusing on sides and angles of various shapes. Through activities such as the "Sides and Angles Worksheet," "Plane Geometry: Sides Printable," "Recognizing Shape Sides Worksheet," and "2D Shapes: Counting Sides," students will enhance their ability to identify, count, and compare the sides and angles of different two-dimensional shapes.

This lesson is crucial for several reasons. Firstly, it lays the groundwork for understanding more complex geometric concepts in future grades. It helps students develop spatial awareness and visual perception skills, which are essential for interpreting and navigating the world around them. Recognizing shapes and their attributes also plays a significant role in developing problem-solving and critical thinking skills. Furthermore, these activities foster attention to detail and precision, qualities that are invaluable not just in mathematics but in everyday life. By mastering these concepts, students are set on a path to success in their mathematical journey, building a strong foundation for subsequent learning.

• ### Activity 1 / Sides and Angles Worksheet

A side is a straight line used to form a shape, just as pictured in the worksheet. An angle, on the other hand, is formed at the point where two sides meet, as also pictured in the exercise. Before going into this exercise, you must first make sure that your children fully understand what you have just explained. Then, help them complete the tasks in this printout. Check the birds that are holding shapes by their angles in the first exercise. In the second exercise, your kids must check the birds that are holding shapes by their sides.

• ### 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!
