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

Important Announcement about Online Courses and LEARN NC.

Important Message about LEARN NC

LEARN NC is evaluating its role in the current online education environment as it relates directly to the mission of UNC-Chapel Hill School of Education (UNC-CH SOE). We plan to look at our ability to facilitate the transmission of the best research coming out of UNC-CH SOE and other campus partners to support classroom teachers across North Carolina. We will begin by evaluating our existing faculty and student involvement with various NC public schools to determine what might be useful to share with you.

Don’t worry! The lesson plans, articles, and textbooks you use and love aren’t going away. They are simply being moved into the new LEARN NC Digital Archive. While we are moving away from a focus on publishing, we know it’s important that educators have access to these kinds of resources. These resources will be preserved on our website for the foreseeable future. That said, we’re directing our resources into our newest efforts, so we won’t be adding to the archive or updating its contents. This means that as the North Carolina Standard Course of Study changes in the future, we won’t be re-aligning resources. Our full-text and tag searches should make it possible for you to find exactly what you need, regardless of standards alignment.

  • In math, "elegant" means "cool"!: An elegant solution to a math problem is one that requires less time and work. Encouraging students to find such solutions will help them build number sense or numeracy.
  • Math Fun: We have compiled some of our favorite mathematics instructional resources to help students develop a sense of numbers and how they are used by us everyday. Students will have fun practicing their skills and trying new problem-solving ideas.
  • Telling time practice: Students will practice telling time skills using an applet developed by Shodor Educational Foundation, Inc. Permission has been granted for the use of the materials as part of the workshop "Interactivate Your Bored Math Students."

Learning outcomes

Students will:

  • sort objects based on color.
  • make reasonable estimations.
  • determine less than, more than, or equal to relationships.
  • write fractions to show the number in a set.
  • use available information to create tally charts, pictographs, and bar graphs.
  • solve division problems using manipulatives.
  • examine and explain information presented in a tally chart, pictograph, and bar graph.

Teacher planning

Time required for lesson

45 minutes


  • Individual size bags of M&M’s for each student
  • One copy of each worksheet for each child: M & M Math
  • Colored pencils, markers, or crayons.

Technology resources

  • Computer with access to internet and a CD Rom Drive.
  • Optional: CD “Graphers” by Sunburst.


Conduct an internet search of chocolate. Discuss where chocolate comes from, how it is processed, and the business and economics of producing chocolate.


  1. Give each child one bag of M&M’s and a handout. Go over the directions for each set of problems.
  2. Have students complete the handout and the graphs.
  3. Follow up with discussion questions:
    • Does every bag of M&M’s contain the same number? How can you explain this?
    • What combination of two colors produced the greatest amount of M&M’s?

Extension Activities:
Prepare graphs of other types of activities in the classroom using the program Graphers by Sunburst.


Students completion of the handouts as well as participation in class discussions will be used to assess their understanding of the concepts covered.

Supplemental information

This activity is a good follow up or introductory lesson to a unit based on Charlie and the Chocolate Factory or The Chocolate Touch.


My children always enjoy this activity. We use it in correlation with a unit on chocolate as we are reading Charlie and the Chocolate Factory.
