In geometry, there is a lot of new vocabulary for students to master. Not only do they need to identify shapes such as rectangle and triangle, but they need to be able to identify parts of shapes, such as base, leg, obtuse angle, vertex, and more! Building charts for students or with students can help them organize new concepts and have a point of reference for review. In this activity, students will **create an illustration and provide a definition for each geometry term.**

Students recognize squares, circles, and triangles easily enough, but words such as “ray” and “perpendicular” are usually new terms. These unfamiliar words are also fundamental in understanding more complicated geometry. Keep charts clean and simple as much as possible. If the example pictures on the chart are too distracting, try a separate slideshow with multiple examples as you go over new words with your group or class.

Point | A single location in space or on a flat surface |
---|---|

Line | A collection of points that continues forever in both directions |

Line Segment | A part of a line with two endpoints |

Ray | A part of a line with one endpoint |

Angle | Two rays that share an endpoint |

Parallel Lines | Lines that never intersect |

Intersecting Lines | Lines that pass through the same point |

Perpendicular Lines | Lines that intersect and form four right angles |

**Student Instructions**

Create a chart that defines and illustrates examples of geometry terms.

- Click "Start Assignment".
- Label the columns "Picture", "Names", "Definition", and "Example".
- In the names column, use textables to type the geometry terms you will put on your chart.
- Create a picture for each term, use textables to define it, and provide a real life example of the term.
- Save an submit your storyboard.

**Grade Level** 2-3

**Difficulty Level** 2 (Reinforcing / Developing)

**Type of Assignment** Individual or Group

- [Math/Content/4/MD/C/5] Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
- [Math/Content/K/G/A/2] Correctly name shapes regardless of their orientations or overall size.
- [Math/Content/K/G/B/4] Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).
- [Math/Content/4/G/A/1] Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
