The first 3 graphs ask for range and median.

The next two slideshave 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 Tubeor 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 timeuntil you reach the median.
