• I really want to integrate this into Big History. I have been working on making my own writing companions for all of the units. Unfortunately, it's taking more time than I thought. Easy Writing is a good fill-in while I work on my companion books. It will set them up for solid sentence work and familiarize them with combining sentences, appositives, along other methods WR uses. The main idea for WR is to apply writing to subjects that are currently being covered. Easy Writing gets the structure, but the sentences are out of context making writing an entirely separate subject than Big History. 

• Easy Grammar Plus
• Aligns well with Easy Writing. Easy Grammar Plus is the perfect book to cover all of the grammar bases for around 7th grade and up through high school. 

• Megawords 2 and part of 3

• The Art of Cursive Handwriting

• Trying something new here. This is my attempt at covering all of my bases for my 8th grade mildly dyslexic. I like that it's a workbook we can discuss together. I like that it pulls words from all types of sources, fiction, nonfiction, speeches, and primary sources. They see the word in multiple settings - in context, analogies, synonyms/antonyms, shades of meaning, multiple meanings and other ways. It also includes word study of roots, affixes, idioms and sayings, academic language, and figurative language. You can see samples here.

If you want to make it easy on yourself or skip signing up online, there is the DK Big History book that covers every Threshold, every topic that the online component uses in one book. It is written for middle school students. You can use it as a spine for history and science or as is. Of course DK means all of the pages are full of colorful images. It is a huge, heavy book that is available in hardcover only. I would prefer it on the Kindle only because I have two kids and buying two (three if you count me) copies gets bulky and expensive.

For Elementary Students I recommend A Really Short History of Nearly Everything by Bill Bryson

• The Secrets of the Immortal Nicholas Flamel by Michael Scott - I happen to love this series specifically for Big History because it brings together characters from mythology and history while working in multiple time periods. It is also a long series that could last the whole year. It's fun to read on the Kindle because we can look up all of the references as we go along.
