Mathematics Grade 5
Strand: GEOMETRY (5.G)
Graph points on the coordinate plane to solve real-world and mathematical problems in quadrant one (Standards 5.G.1–2)
. Classify two-dimensional figures into categories based on their properties. (Standards 5.G.3–4)
Classify two-dimensional figures in a hierarchy based on properties.
Always, Sometimes, Never
The purpose of this task is to have students reason about different kinds of shapes based on their defining attributes and to understand the relationship between different categories of shapes that share some defining attributes.
An Introduction To Quadrilaterals
In this lesson the student is introduced to parallelograms, rectangles, and trapezoids and practices creating various types of quadrilaterals.
This lesson is all about classifying polygons. Students play a game where they have to sort a group of polygons based on their properties. They then use the Annenberg interactive to solve puzzles and draw polygons when given a set of clues.

This video teaches students strategies to identify the properties of quadrilaterals. The emphasis is on parallelograms. Students create posters explaining the properties of quadrilaterals in the classroom activity.

Classifying Triangles by Angles and Sides
A middle-school student named Julia explains the classification of triangles by the use of angle measurements and side lengths in this introductory video. Students then take their understanding and use it in a scavenger hunt around the classroom finding triangles of different types.

Geometry - Fifth Grade Core Guide
The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Fifth Grade Mathematics - Geometry (5.G)
Geometry and Classification of 2D Figures: Bianca Busts a Move
After breaking a friend's table while dancing on it, Bianca must use her knowledge of measurement and geometry to get a piece of wood to fix it. In the classroom activity students create tabletop designs in order to use their knowledge of perimeter and area.

This lesson and activity will help the student understand how to classify two-dimensional figures based on properties. The student manipulates shapes to create now polygons.
What do these shapes have in Common?
This task asks students to classify shapes based on their properties. The task itself is straightforward, but there are a number of opportunities to present this task in class and push the level of discussion and reasoning.
What is a Trapezoid? (part 2)
The purpose of this task is for students to compare different definitions for trapezoids.
