## Geometry Curriculum Track In the fifth grade lessons, students are introduced to the coordinate plane, learn how to graph points in the first quadrant, and identify the coordinates of graphed points. They solve both real-world and mathematical problems by graphing points and interpreting the coordinates of points in context. They further refine their understanding of the relationships among the shape categories encountered throughout the K – 4 geometry lessons and create a complex classification of two-dimensional shapes using Venn diagrams.

#### Lesson 1: Introducing the Coordinate System

Students are introduced to the basic structure of the coordinate plane and how it can be used to describe the location of points. They apply their understanding by graphing points given their coordinates and by describing the coordinates of graphed points.

• CCSS.MATH.PRACTICE.MP6

### MyStemKits 3D Kits Used

• Graphing Kit (optional)

#### Lesson 2: Graphing Shapes in the Coordinate Plane

Students apply their understanding of graphing on the coordinate plane. They will practice graphing points given the coordinates and describe the polygons created by connecting the points.

#### Lesson 3: Graphing Data in the Coordinate Plane

Students are introduced to two-variable data that can be graphed in the first quadrant of the coordinate plane. They collect, graph, and interpret data in context.

#### Lesson 4: An Introduction to Venn and Euler Diagrams

Students are introduced to Venn and Euler diagrams as a means of displaying the relationships among sets of objects. They both construct and interpret Venn diagrams to show the relationships among real-world sets, sets of numbers, and sets of shapes.

• Basic Shapes: Polygons
• Basic Shapes: Triangles
• Basic Shapes: Right Solids

#### Lesson 5: Classifying Triangles Using Venn and Euler Diagrams

Students review the angle types and triangle classifications. Then they use Venn diagrams to show the relationships among the sets of scalene, isosceles, equilateral, acute, right, obtuse, and equiangular triangles.

• CCSS.MATH.CONTENT.5.G.B.3
• CCSS.MATH.CONTENT.5.G.B.4

#### Lesson 6: Classifying Quadrilaterals Using Venn and Euler Diagrams

Students review the defining attributes of the special quadrilaterals (parallelograms, trapezoids, kites, rectangles, rhombuses, and squares). Then they use Venn diagrams to show the relationships among these sets.
