Chapter 2 Graphical Representations

Lesson 2.3 Histograms

Formula page

I expect that you will be able to use a formula page for this class,  but that will be determined by your teacher.

Your teacher may have a formula page they expect you to use.

Below is a link to the formula page I will use (at least for now!) when I’m doing questions for this class.

This may change, depending on feedback from your teacher.

I encourage you to download this page and print it so you have it handy when you are doing math.

Grayscale Grids

You may want to print some grid paper for the graphs you will be creating in this unit.

Below are links to two documents that have grayscale grids.
These are grids that have been created at various shades of gray, from black down to light gray.
It can be very helpful to have a lighter grid to work on, so the lines are less distracting.
You can experiment with your personal preference as well as your printer to see what works best.
Once you find a page that works,  most printers will let you print copies of  just that page.

NOTE!   If you work with these grids and feel like you would prefer a different size, different size squares, etc.,  LET ME KNOW!
I can easily create a document with grids of different sizes if that would help you with your work in math class.

I would recommend printing a bunch of copies to have on hand for your work in math class.
