Intro to Geometric Figures

The goal of this map is to give teachers an outline with resources for planning and teaching a unit about Introduction to Geometric Figures.

Figures in the Plane

The most basic shapes of Geometry are points, lines, segments, rays, and angles. This branch is the foundation for the rest of the unit. Although this is basic information, it can be customized to fit curriculum from Kindergarten to University. The video lesson is cleverly constructed and will keep all the Yale Geometry snobs entertained.

Line Segments and Distance Between Points

Video Lesson: Intro to Lines, Line Segments, & Rays

Distance Between Two Points: Resource with Visuals & Formulas

Rays, Angles, and Angle Measure

Rays, Angles, Angle Measure Lesson, Worksheet, & Rubric

Measure & Classify an Angle Lesson with Video

Pairs of Angles and the Corresponding Angles Theorem

Corresponding Angles: Definition, Theorem, & Visuals

The Measure of Angles in Triangles

Lesson Resource: Angles of a Triangle, Equilateral, Ratio of Angles

Directed Angles

Article "How to Use Directed Angles"

Points and Lines

Video Lesson: Line Segments, Lines & Rays

Points & Lines Intro & Definitions

Curves and Polygons in the Plane

Any kid who scribbles knows a curve. This branch takes it a step further by providing resources about how these scribbles interact in the plane. Polygons appear in this branch with beautiful artwork and children teaching about regular versus irregular. The triangle rap video is super simple but can entertain a wide range of students with it's beat and engaging physical instructions. You can't teach curves without showing students a video of a skateboarder on a half-pipe.

Figures in Space

This branch gets a little heavy with formulas, definitions, and equations. Fear not Kindergarten teachers: grab some blocks, cylinders, and cones to teach the topics of this branch. Word on the street is that Euler's favorite flavor to put in an ice cream cone was bubble gum. There is some complex artwork using polyhedra.
