Summary
Give kids a taste of a sequence, let them build an understanding, and then see how far their predictions can take them.
- Students begin by looking for patterns and predicting the number of squares at step 5.
- I reveal the solution (it's 24) and students work on predicting step 12.
- After revealing the solution (it's 52), I reveal an algorithm to predict any step and challenge students to calculate much larger steps. Answers – Step 63: 64 × 4 = 256 – Step 97: 98 × 4 = 392 – Step 821: 822 × 4 = 3288
