ABC's of Geometry


During this lesson students explore the world of geometry on the Internet. Students create their own list of terms by navigating geometry sites. Students also reinforce what they have learned using interactive Internet sites.

 Associated Standards and Objectives 
Content Standard(s):
TC2 (3-5)
2. Use various technology applications, including word processing and multimedia software.
  • Using navigational features commonly found in technology applications
  • Identifying digital file types
  • TC2 (3-5)
    3. Identify common hardware and software problems.
  • Determining basic troubleshooting strategies to correct hardware and software problems
  • TC2 (3-5)
    8. Collect information from a variety of digital sources.
    Examples: online libraries, multimedia dictionaries
  • Using technology tools to organize information
  • Demonstrating efficient Internet search strategies
  • Example: keyword search
  • Evaluating electronic resources for reliability based on publication date, bias, accuracy, and source credibility
  • MA2015 (3)
    24. 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. [3-G1]
    ELA2015 (4)
    43. Acquire and use accurately grade-appropriate general academic and domain-specific words and phrases, including those that signal precise actions, emotions, or states of being (e.g., quizzed, whined, stammered) and that are basic to a particular topic (e.g., wildlife, conservation, and endangered when discussing animal preservation).

    Local/National Standards:


    Primary Learning Objective(s):

    Students will locate information on Internet sites. Students will create a list of geometry terms with definitions.

    Additional Learning Objective(s):

     Preparation Information 

    Total Duration:

    Greater than 120 Minutes

    Materials and Resources:

    Sir Cumference and the First Round Table by Cindy Neuschwander

    Technology Resources Needed:

    Computers with Internet access, printer, ABCs of Geometry worksheet (see attached)


    Students will need some basic understanding of geometric terms and vocabulary. The teacher will need to copy the attached worksheet file to each of the computers the students will be using.

    1.)Begin the lesson by asking students to describe what they know about geometry. Then read the story Sir Cumference and the First Round Table.

    2.)After reading the story, discuss the geometric terms used in the book. Inform students that they are going to create an ABC geometry term sheet by using terms they know and new terms they find on the Internet. Before allowing students to begin, visit the following sites to help students learn more about geometry.
    This site shows different types of geometric shapes.

    This site has a few presentations about geometry that teachers can use when teaching geometry.

    4.)When the review is complete, have students open the attached worksheet document on their computers. Then allow them time to search the sites below for terms for each letter of the alphabet. Students will type the terms and definitions into the worksheet document.
    (Visual Geometry Dictionary)
    This site is a dictionary of illustrated math terms.

    This is a site of geometric terms.

    (Geometry Glossary)
    This is a site about geometry terms.

    7.)When students have completed the assignment, ask students to print the worksheet. Then allow them time to explore the geometry games from the websites below.
    (Geometry Workbench)
    This site allows students to create geometric shapes. Click PLAY to begin.

    (Geometry Terms)
    This site tests students knowledge of geometry terms.

    **Some files will display in a new window. Others will prompt you to download.

    Assessment Strategies

    The teacher will check students' geometric terms for accuracy.


    As an extension, the students can read Sir Cumference and the Great Knight of Angleland: A Math Adventure. Students could use MS Paint software to illustrate the terms in their geometry dictionaries.



    Each area below is a direct link to general teaching strategies/classroom accommodations for students with identified learning and/or behavior problems such as: reading or math performance below grade level; test or classroom assignments/quizzes at a failing level; failure to complete assignments independently; difficulty with short-term memory, abstract concepts, staying on task, or following directions; poor peer interaction or temper tantrums, and other learning or behavior problems.
