This site is a game changer!
I am assembling a few sample lessons, but for those of you that need to dig in, I highly recommend signing up for an account. It is a freemium account, so it will start free and then a fee is charged after a certain amount of lessons, I believe it is five. But, follow me on twitter (@trenddteacher) because I have been posting codes when I can get my hands on them!
I love that it has a teacher dashboard, teacher-created content and allows for formative assessment and discussion options. This would be fantastic for a blended learning environment, or close reading documents online. Comment below if you have any experience or insight after learning this resource in your classroom.
