Every textbook has a certain number of -ER verbs it introduces in one of the beginning chapters. This is a handout I made to supplement whatever textbook I have.
Page 1 - list of -ER verbs (more than any book that I've ever seen gives)
Page 2 - list of -CER verbs (and info on how to conjugate them) and a list of -GER verbs (and info on how to conjugate them)
This is also a great resource for differentiation, as it can be given as supplemental material for kids in level 1 who need a challenge.
