Content Update: December 2017 (ATTACK of the STATS)

For all of you who've been pleading with us for new stats content, December was your month! Most of our new content was around statistics, and we also added some interesting new items to our Career series, as well as a few History and Math items. Enjoy!

My progress in Algebra I !!!

Three things:

1. Normally, I would have posted under the more recent January list, but that one is closed to comments. This one isn’t, so I’m posting my two original comments here.

2. Will a list of new February 2018 content be forthcoming? I check these for new items for courses I’ve already finished so that I can go back and do them. If you have not had time to do a February list and have decided that it’s too far into March to do one, please don’t forget to put them in your March list (or whenever you do your next one)!

3. I noticed that Early Math contained just about all, if not exactly all, of the content for Kindergarten, 1st Grade, and 2nd Grade, with a small amount of the content for 3rd Grade. The last time I checked, though, the new 2nd Grade module Estimate lengths (US Customary units) had not been added to Early Math. I’m bringing this to your attention in case it was an oversight on your part. On the other hand, you may have a desire to keep the focus in Early Math on worldwide applicability, without “soiling” it with US Customary units content. If so, then you can disregard this item.
