 Teacher noteEncourage multiple strategies when solving: tables, an algebraic equation, graphing, etc. Challenge: get your students to write a rule (function).
*Note: there is more than one rule that will work.
There are four pictures for the cup. Use what you need:
"Cup Height" gives the total cup height.
"Lip Estimate" allows students to estimate about the lip height.
"Lip Height" give its height.
"Lip and Cup Height" will give all the dimensions students might need.
Door frame:
***We've got a conversion here as the door height is given in inches and the cups are measured in centimeters.
[close up] Identify the specific point of measuring the door frame height.
[Estimate 1] Use Mr. Stadel's height to estimate the height of the door.
[Estimate 2] Estimate the height of the door.

How much faster would you reach the "top" if you alternated the direction if the cups?





How many cups until you reach the top of the door? (Or the top of Mr. Stadel, but I knew that's what you were after.)

How many cups to reach the top of the door? How will you stack the ones at the top?























How tall is the tower after all 50 cups are nested on top of each other?

Is there a way to calculate the number of cups to 40 without having to stack the cups one by one?




















how many cups will it take to reach the top of the door frame? What's the 40 for?
