I use The Economy by the CORE Team: core-econ.org.
I used worksheets for in-class exercises for a variety of units in the book, mainly Units 2 through 9. You can download a zipped file of all of the below here.
You can access the quizzes we made for the course here. They are flawed and we havenโt had a chance to correct them all, so please do go over them before posting them for your students. You can download them here.
