Student Discussion Activity
Introduction
This activity is a fun activity that is designed to show how the shortrun average cost curve is produced.
Basically, the activity gets student/s to write the word “MArkETInG” on the board in this precise mix of upper and lower case letters (or any other suitable combination will do).
The word “MArkETInG” is the pretend product that is being produced and sold. However, the goal of the activity is to calculate an average cost curve using various levels of input.
Information on Production Costs
Allocated fixed costs 
$100 per period 
Semivariable costs = student labor 
$10 per student per 30 seconds 
Semivariable costs = pen/marker 
$10 per period 
Variable costs = the word “MArkETInG” 
$10 per word 
Then simply follow the boxes below and then plot the average cost curve using the above cost data.
How to Play
Round One
· The student is given one pen/marker only · One student writes MArkETInG (reasonably neatly) as many times as possible in 30 seconds · Then the average cost is calculated (see example on the next page) 
Round Two
· The same student again writes MArkETInG as many times as possible in 30 seconds · This shows any benefits from experience in reducing average costs · Then the average cost is calculated again 
Round Three
· A second student is asked to join the first student · The students have two pens/markers between them · Together they write MArkETInG as many times as possible in 30 seconds · This shows any benefits from shortterm production increases · Then the average cost is calculated again 
Round Four
· A third student is asked to join the first two students · The students have three pens/markers between them · Together they write MArkETInG as many times as possible in 30 seconds · Then the average cost is calculated again 
Teaching note: the game then continues as required, depending upon the number of students/teams in the class.
Some Scoring Examples
Round One 
Round Three 

Fixed costs 
$100  $100 
Labor  $10 (one student) 
$20 (two students) 
Pen/marker 
$10 (one pen/marker)  $20 (two pen/marker) 
Word cost  $80 (8 written) 
$200 (20 written) 
TOTAL COSTS 
$200  $340 
Words produced  8 
20 
Average cost 
$25 ($200/8) 
$17 ($340/20) 
Note: The instructor (or a nominated student) can record the average costs for each round, and then these costs can be plotted onto a cost curve on the board (or a spreadsheet) at the end of the rounds.
