237: Pick a Number
Step 1: pick a 1 digit (16) number and roll 1 die to record the number of rolls that it takes to get your selected number.
Step 2: pick a two digit number (1166) and roll 2 dice and record the number of rolls to get your selected number. [Note: Read the dice from left to right as they fall on the table. For example, a 4 and a 3 would read as the number 43.]


Continue likewise with 3 and 4 dice and record the results. On a graph, plot the number of dice vs. attempts to get your selected number.
