Remember the line plots you worked with in previous sessions? If you reshuffle your stacks of coins just a bit, you can create a line plot representation that corresponds to the number of coins in each of the nine stacks, which will allow us to explore other interpretations of the mean. Note 5
To do this yourself, create a line plot on your paper or poster board. Across the bottom of the page, draw a horizontal line with 10 vertical tick marks numbered from 1 to 10 (placed far enough apart for an adhesive dot or note to fit between each). Your number line should look like this:
Set up your 45 coins in this ordered allocation:
Now arrange the stacks of coins on the paper above the number that corresponds to the height of each stack, like this:
Note that the 2 stacks of size 4 and the 2 stacks of size 6 are placed above the same number.
To form your line plot, replace each of the stacks with an adhesive dot or note. You should now have a line plot that looks like this:
Each dot in the line plot corresponds to a stack of that specified size.
