The first 3 graphs ask
for range and median.
The next two slides
have songs and
vocabulary
for range and median.
Range:
The highest number minus
the lowest number from
numbers on a graph.
Song:
Home, home on the range,
Where the biggest number is first,
Then minus the lowest, and don’t
work the slowest,
The difference you get is the range.

Listen to Bing Crosby singing "Home on the Range" on You Tube
or just listen to the music
(scroll down to see all options on the Bus Songs page)
Difference is the answer in subtraction.
Meidan:
The middle number from an
ordered set of numbers
from a graph.
Song, tune is CLEMENTINE:
Oh my darling, oh my darling,
oh my darling, median,
You were lost and gone forever,
but I learned you once again.
First you line up all the numbers,
in order from a graph,
Cross off both the ends at a time
until you reach the median.

You Tube or listening options
