Vocabulary

  • Induction
  • Proof
  • Integer
  • Combinatorics
  • Regression

About the Lesson

Introduction to Induction - Students explore triangular numbers through a combination of visual and numerical representations including Pascals Triangle. Through these structures students establish a formula and conclude by proving their formula works for all whole numbers. The teacher notes includes answers, a slide show is also available for download to provide powerful visuals to the entire class.
