Activity Overview
Students investigate patterns in ordered pairs generated by constructing a sequence of similar shapes. They will then use the patterns and the calculator to predict the number of blocks it will take to build a specific shape in the sequence.
Before the Activity
See the attached PDF file for detailed instructions for this activity
Print student activity sheets pages 38 - 39 from the attached PDF file for your class
During the Activity
Distribute the pages to the class.
Follow the activity procedures:
Use triangle Pattern Blocks to make a pattern of a larger triangle
Predict how many triangles it will take to make the next larger triangle of the same shape
Record the number of blocks used and find the area of the triangle
Use the calculator to predict the area of the 95th triangle
Choose a different Pattern Block and repeat the activity
After the Activity
Review student results
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
