Is there a textbook I can use to teach LibreOffice in our high school?

Is there a textbook for LibreOffice I could order? I need something simple that high school or middle school students could follow step by step.

We have a PC lab with Windows.

I am presently working on a brand new high school course for teaching LibreOffice. It consists of 10 units of 12 lessons each. I just finished the 4th unit. I project being done in another 13 months or so.

I’m writing this under contract with Christian Light Publications; specifically, Christian Light Education.
