This is the website I first used when I learned about UbD a couple years ago, as I was a bit confused after class. It does a great job of explaining things in layman's terms, and even non-educational lingo for other majors. Great to utilize when explaining, identifying, or attempting to identify UbD.
Same website as listed prior to, but a different page link. I've heard a few people were having some trouble, just another example and explanation of the UbD template. Similar to the ones listed in the text and workbook, but thought the more resources available, the better!
This has been so helpful for me when writing my lesson plans! Just click on the grade level and you will get a side-by-side comparison of common core standards and NH state standards.
