K-12 Teaching and Learning From the UNC School of Education

LEARN NC was a program of the University of North Carolina at Chapel Hill School of Education from 1997 – 2013. It provided lesson plans, professional development, and innovative web resources to support teachers, build community, and improve K-12 education in North Carolina. Learn NC is no longer supported by the School of Education – this is a historical archive of their website.

  • Exploring geometric shapes: These hands-on activities make learning about geometric shapes more appealing to students.
  • Painted cylindrical sculptures: Students will experiment painting a variety of lines as directed in addition to inventing their own on 12" x 18" paper. Students will also glue pre-cut paper strips onto their sculptures experimenting with a variety of paper sculpture techniques such as bending, folding and curling.
  • Pattern block addition: Students will practice addition, problem solving, and writing equations in the context of a fun and challenging pattern game.

Learning outcomes

Students will:

  • be able to identify properties of polygons with the use of pictures from newspapers, magazines, and, if access is available, pictures from the internet
  • identify line segments, angles, solid geometric figures, and plane surfaces in real world objects
  • learn to write a summary of their work

Teacher planning

Time required for lesson

1 hour


  • newspapers
  • magazines
  • scissors
  • paste
  • poster board or construction paper
  • notebook paper and pencil
  • crayons (optional)

Technology resources

  • computer with access to the internet (optional)
  • word processing program (optional)
  • HyperStudio 3.1 version


  • Using the overhead projector, review polygons including quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons and discuss the qualities of each.
  • Students complete the Hanging Polygons activity.
  • Allow the students to make solid figures such as a cubes, rectangular prisms, triangular prisms, etc. using patterns of the two-dimensional figures in the attachment For example, six square patterns taped together would make a cube.
  • As a homework assignment, the day before this lesson have students bring in newspaper and/or magazine pictures they believe include polygons and solid geometric figures.


  1. Introduce the lesson with the Hyperstudio presentation “Geometry In Our World” using classroom TV and computer hookup (if this is not available skip this step).
  2. Give each student a newspaper, construction paper/poster board, scissors, and glue. Adding to the collection from their homework assignment, have the children continue searching for polygons and geometric figures until they have a sufficient supply to completely cover the entire surface of their paper.
  3. Next, have the students glue their pictures on the paper to make a collage.
  4. Students can carefully add color to their collages by lightly coloring the newspaper pictures they have included.
  5. Finally, tell the students to write a summary of the collage describing the kinds of geometric figures it includes. The summary should be at least two paragraphs long and include only the most important information about their collage.
  6. Post the students’ final products on a bulletin board or hallway wall for all to admire.
  7. For homework, students complete the Discovering Polygons activity sheet.


  • Evaluation of student summary and collage
  • Activity sheet: Discovering Polygons
