The amount of teachers who don’t know that there is a common core app for your phones breaks my heart.
Not only does it have all the standards sorted by subject and grade level, you can also add notes to the standards on the app. So if your lesson for a reading standard just rocked you can make a note of that lesson on the standard. There’s also a great search feature for those days when you swear you were just staring at the standard you needed but now can’t find it.
They also have one for the Next Generation Science Standards as well!
