Here's an 11-minute video providing the basics of formula writing:
There's a minor mis-statement in this video -- teachers try to be perfect but little mistakes are made.
Here is a worksheet just for binary ionic formula writing:

This worksheet contains several pages, topics which I will address later -- you can pick and choose which pages to use in class:

Next Friday, I will continue Ionic Formula writing with polyatomic ions and transition metals.
Mole Day is October 23rd, next Thursday! I am going to post a few Mole Day activities on Monday, 10/20.
I posted a Mole Town Map on January 10, 2014 if you want to check that out.
I have just added a Topic List to help you to find past Blog entries you're looking for. I hope it helps!
Buy my lab book "Chemistry on a Budget" -- it is available for $20 at amazon.com or $23 at lulu.com:

This book contains 13 labs using consumable materials purchased from local stores. There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
Have a good weekend!
