How Many Will There Be? Crosses
Objective
Students will use the patterns they find in the first few steps to predict a step much further along.
Inspired by the website Visual Patterns.
Steps
- Students predict how many squares there will be at step 5.
- I reveal the solution (it's 29) and ask students to predict step 12.
- After showing the answer (it's 64), I challenge students to predict any step! Answers – Step 50: 453 – Step 101: 912 – Step 999: 8,994
