In this activity, students will look for both number patterns and visual shapes that go along with quadratic relationships. Two applications are introduced after some basic patterns in the first two problems.
On page 1.2, students see the ordered pairs that will be plotted on the next page. Focus on the y-values and see if you can figure out a mathematical pattern. The students are asked to write an explanation if they can. Some may attempt to explain the – 4, – 3, – 2,… pattern, while others may recognize immediately that the y-values are the “perfect squares”.
