3. #5 Intuition: Estimate the number of cups in a stack that is as tall as your math teacher?

4. #6 Intuition: Give a range of reasonable answers to the number of cups in a stack that is as tall as your math teacher?

5. Estimate the number of cups in a stack that is as tall as your math teacher? Avoid these mistakes

6. 11.5 Precision About 11.4 in 11+(5/16)=11.375≈11.4

7. Estimate the number of cups in a stack that is as tall as your math teacher? Create an estimate. Give clear, convincing evidence that your estimate is accurate. (Write something that would convince your boss) Generalize: create written steps, a graph and/or a variable expression that could be used to find the height of stacks with different numbers of cups. 7.

8. A stack of 3 cups is 7.5 inches tall. The relationship between number of cups and height of stack (inches) is modeled by the recursive function: Next=Now+0.7 8.26.8 Cups2345 Height (inches) 7.5 8.98.2 6.8
