# MAFS.3.G.1.1

Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
General Information
Subject Area: Mathematics
Domain-Subdomain: Geometry
Cluster: Level 2: Basic Application of Skills & Concepts
Cluster: Reason with shapes and their attributes. (Supporting Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Test Item Specifications

• Assessment Limits :
Shapes may include two-dimensional shapes and the following quadrilaterals: rhombus, rectangle, square, parallelogram, and trapezoid. Items may reference and/or rely on the following attributes: number of sides, number of angles, whether the shape has a right angle, whether the sides are the same length, and whether the sides are straight lines. Items may not use the terms “parallel” or “perpendicular.” Items that include trapezoids must consider both the inclusive and exclusive definitions. Items may not use the term "kite" but may include the figure.

## Lesson Plans

Coding Geometry Challenges #1-7, 14 & 15:

This set of geometry challenges focuses on creating a variety of polygons as students problem solve and think as they learn to code using block coding software.  Student will need to use their knowledge of the attributes of polygons and mathematical principals of geometry to accomplish the given challenges. The challenges start out fairly simple and move to more complex situations in which students can explore at their own pace or work as a team. Computer Science standards are seamlessly intertwined with the math standards while providing “Step it up!” and “Jump it up!” opportunities to increase rigor.

Type: Lesson Plan

Artistic Alley:

Students will use their knowledge of how to identify quadrilaterals and how to analyze data to determine a ranking for the best paver designs for a driveway. In this MEA, students will deepen their understanding of the attributes of parallelograms, rectangles, squares, trapezoids and quadrilaterals that do not belong to any of these categories.

Type: Lesson Plan

Area Architects, Lesson 1:

In this unit on area, students explore geometric measurement by becoming "Area Architects" in order to learn the concepts of area. Using all five lessons will allow the students to discover, explore and eventually relate area to multiplication and addition. This lesson is the introductory lesson of the unit. In Lesson 1, students will develop strategies for finding area by counting square units. Students will learn the importance of accurately measuring area by exploring the concepts of area in realistic applications.

Type: Lesson Plan

This is an interactive lesson that allows students to inquire, learn, and successfully categorize various quadrilaterals. They will love the challenge and have fun working collaboratively in the classroom.

Type: Lesson Plan

2D Discoveries:

In this lesson, third grade students will explore quadrilaterals and identify their attributes through sorting and drawing activities.

Type: Lesson Plan

In this lesson, students categorize shapes by comparing and analyzing the attributes of quadrilaterals. Students use shared attributes to establish categories.

Type: Lesson Plan

This is a fast-paced lesson that includes classifying quadrilaterals and parallelograms using geoboards and an interactive whiteboard flipchart.

Type: Lesson Plan

This lesson helps students to realize that shapes have attributes that define them. Students should also discover that a shape can have multiple names based on the definitions of that shape.

Type: Lesson Plan

Shape Up or Ship Out!:

In this lesson, students will sort two dimensional shapes according to their likenesses or differences. Students will enjoy doing the "drawing lines" activity. The students will learn how to classify these shapes according to shared attributes. They will use these properties to understand the world of geometry as they progress in their schooling.

Type: Lesson Plan

The teacher begins the lesson by reading The Greedy Triangle to the class to review shape names and attributes. The students create shapes using geoboards and follow up their exploration with Shape Concentration (a game played with a partner). The teacher gathers the students together (whole group) and completes a large Venn Diagram comparing two different shapes. The students write in their journals observations they discovered during the lesson along with creating four squares in their journals (1st square - write word, 2nd square-write definition including attributes, 3rd square - draw a picture, 4th square - draw an example).
