I was updating my Box and Whisker Activity over the summer and it occurred to me that I should share a pretty easy way to make your own Box and Whisker plot (B&W).   (p.s. if you have this activity and haven’t downloaded the most updated version… GO GET IT!!  Tons of new stuff added in!  I do think you will enjoy it a bit more!)

When I started teaching B&W plots, I used to create two rectangle shapes, and two lines and try to piece-meal everything together.  However, I always got super frustrated when nothing line up correctly or if I needed to change the image I made into a different B&W plot.

And then….. then it occurred to me that I could use tables to make my B&W plot AND because of how tables function, I could easily adapt one B&W plot into another without having to move too much around – SCORE!  I L.O.V.E making things more efficient!

So, without further adieu, I present to you – HOW TO MAKE AN EASY BOX AND WHISKER PLOT!

Step 1, make 2×4 table

Step 2, merge the cells in column 2, then merge the cells in column 3.

Step 3, turn off the table “border” on the 4 “outer” cells.

To turn the border off on the top left cell – turn off the top border, and the left border

…on the bottom left cell – turn off the bottom border, and the left border

… on the top right cell – turn off the top border and the right border

… on the bottom right cell – turn off the bottom border, and the right border.

Your “table” should now look much like a B&W plot!

Now the fun begins!  “grab” a line between two cells and move widen any cell you want!

All three of these images are from the same B&W plot!

Remember, just because you can’t see the “far left” or the “far right” borders, they are still there and you can still move them!

Isn’t that SOOOOO easy?  Gimme some feedback!  Will this make your teaching world a little bit easier?
