# Unit 6: 2D Geometry

## Overview

Ever wondered how to teach 2D geometry concepts in an engaging way to your 5th-grade students?

In this unit plan, students will first learn about the coordinate plane by graphing points on the first quadrant and using coordinate system vocabulary. They will then classify quadrilaterals based on their properties, including trapezoids, parallelograms, kites, rhombuses, rectangles, and squares.

Each lesson helps students master the unit through artistic, interactive guided notes, check for understanding, and culminates with a real-life example that explores how these geometric concepts apply in practical scenarios.

## Learning Objectives

After this unit, students will be able to:

• Plot points on the first quadrant of the coordinate plane and identify the coordinates of points.

• Define and correctly use coordinate geometry vocabulary (e.g., axis, origin, coordinates).

• Classify quadrilaterals (trapezoids, parallelograms, kites, rhombuses, rectangles, and squares) based on their properties.

• Classify triangles by angles (acute, obtuse, right) and by sides (scalene, isosceles, equilateral).

• Explain the real-world applications of classifying shapes using coordinate geometry and properties of 2D figures.

## Prerequisites

Before this unit, students should be familiar with:

• Basic understanding of points, lines, and angles

• Knowledge of basic geometric shapes such as triangles, rectangles, and circles

• Understanding of the concepts of perimeter and area

• Familiarity with basic vocabulary related to geometry, such as vertices, sides, and angles

• Ability to plot points on a graph using ordered pairs

## Key Vocabulary
