How Many Will There Be? Stairs
Students will use the patterns they find in the first four steps to predict the 100th step.
Inspired by the website Visual Patterns.
- First, students count the squares in each step, search for three patterns, and predict Step 5.
- Next, they use their patterns to predict Step 10.
- Finally, students try to predict Step 100.
- We review the answer and I introduce two extensions: Triangular Numbers and Carl Friedrich Gauss.
