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.

Learning outcomes

Students will:

  • be introduced to Pascal’s Triangle.
  • be introduced to the patterns in Pascal’s Triangle and complete a 9 level triangle.
  • color the multiples of specified numbers.

Teacher planning

Time required for lesson

2 days


  • An empty Pascal’s Triangle template for 9 levels (See attachment)
  • Crayons, colored pencils, or crayons

Technology resources

Color monitor with access to the internet for each student


  1. Use the activity “Coloring Multiples in Pascal’s Triangle” activity online to introduce Pascal’s triangle. Start with one in the top space. The one or two numbers above each space are added together to form the numeral below. This pattern is continued. See: Coloring Multiples Exploration Questions or use the overhead projector with an overhead copy of Pascal’s Triangle. Talk about the relationship between numbers on Pascal’s Triangle and start to fill in the triangle together. Teacher will be in front of the room and the students will be working on their copies at their seats.
  2. Have students complete their triangle for at least 9 levels, and more if they are able, either in class or as homework once they understand the patterns.
  3. The next day with your completed Pascal’s Triangles students will need coloring materials. Ask students to choose a color to color all the multiples of 3. Then choose another color for the multiples of 5, another for 7. You may want to have multiple copies of a completed Pascal’s triangle and color different multiples (ex: 2, 9, etc.). See Pascal’s Triangle Handout for a completed copy of Pascal’s Triangle. (For additional activities see Pascal’s Triangle).
  4. Now go to your computer(s) and either alone or whole class and do the computer activity Coloring Multiples in Pascal’s Triangle.


Students will be able to complete a 7 level Pascal’s Triangle.(Completing the triangle is not the main objective of this lesson therefore the whole triangle should be completed by all students.)

Rubric for evaluation:

  • No errors-5pts
  • 1-2 errors-3pts
  • 3-4 errors-1pt
  • More than 4 errors-0 pts

Students will then color the specific multiples on their Pascal Triangle.

Rubric for evaluation:

  • Complete 5 different specific multiples without error-5 pts
  • Complete 4 different specific multiples without error-3 pts
  • Complete 3 different specific multiples without error-1 pt
  • Complete 2 or less-0 pts
