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

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

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

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

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.

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 Cups2345 Height (inches)

Next=Now+0.7 Cups Height (inches) (5) ? (24) 22.2 Height (inches) as a function of cups c General expression: Function: h(c) = c Recursive Function: c is # of cups
