Check-In: Questions 12–13

12. The Even Number Eagle can be seen flying through the air on Planet Gzorp. It grows like this.

1. Use square-inch tiles to build a model of the Even Number Eagle up to age 8.
2. Draw a data table like the one below. Record the age in years (A), the new growth in squares (G), and the size in squares (S).

3. Look at your data table. Describe any patterns you see. You can use examples in your descriptions.
• Look down the columns.
• Look across the rows. Look from one row to the next.
• Try to find patterns that use addition, subtraction, multiplication, division, or exponents.
4. Write a rule and a formula for the new growth in squares (G) for any age in years (A).
5. Predict the new growth in squares (G) and size in squares (S) for an Even Number Eagle that is 12 years old. Show or tell how you made your predictions.
1. Write a rule and a formula for the size in squares (S) for an Even Number Eagle at any age in years (A).
2. Use your formula to predict the size (S) of an eagle that is 50 years old.
