Teacher Directions:
Background Information
This activity is best utilized in a classroom environment in which the students have access to a computer and the Internet. Students can view the Coloring Multiples in Pascal's Triangle Web site, interact with the activity, and access the accompanying worksheet through Thinkport. If this environment is not available, the interactive activity can be viewed using a computer with a projection device. Students will need copies of the worksheet if the activity is projected. The first part of the lesson should be projected so that all students can see it in either situation. If a projection device is unavailable, you may print out Fill in Pascal's Blanks worksheet and make an overhead.
This activity is geared towards students in grade four. Students do not need to have a strong understanding of patterns to complete this activity.
The Coloring Multiples in Pascal's Triangle Web site allows students to recognize and continue a numerical pattern. Once students have mastered this skill, students can move on to find more patterns within Pascal's Triangle. To do this, there is another student activity called Multiples and Pascal located on the Thinkport Web site that will extend this concept into multiplication skills and patterns.
Motivation
Say to the students, "Red, Red, Yellow.... Red, Red, Yellow..... Red, Red..." Ask students to finish the pattern and continue it. Then share additional patterns like square, circle, diamond, square, circle, diamond... Share several examples of different types of patterns.
Instruction
Focus for Media Interaction
Say to the students, "You are about to see a triangle pattern. Sometimes patterns can go in different directions, not just from left to right. See if you can detect the pattern."
Viewing Activity
Project the Coloring Multiples in Pascal's Triangle Web site and have the students see if they can detect the pattern. After giving students time to find the pattern, ask students if they can share what they think the pattern is.
Post Viewing Activity
Discuss the patterns found.
Focus for Media Interaction
Say to students, “Let’s see if you can continue the pattern you discovered.” Students are responsible for completing the pattern and checking their work. See Student Directions for steps in navigating the Coloring Multiples in Pascal's Triangle Web site.
Viewing Activity
While accessing the Coloring Multiples in Pascal's Triangle Web site, students will complete the Fill in Pascal's Blanks worksheet. As they finish each row, they need to click on the Increase Depth link on the bottom right side of the screen to check their work. Students may need scrap paper to complete some of the larger number addition.
(Note: If you want to assess work before students check it on the Web site, have students complete the worksheet, raise their hands, and you can spot-check it before students are permitted to check work on the Web site.)
Post Viewing Activity
Discuss any additional patterns students noticed while doing this activity.
Wrap Up
Have students discuss, in their groups, how this pattern differs from other patterns they have worked with before.
