							Auxiliary be and primary modals 
							I made this exercise to train the elementary level students to use their cognitive skills more by understanding the simple grammar rules. Adding or eliciting ´s´ or ´es´, ´ing´ after a verb, the unnecessarily aux-be added in a sentence might base this exercise. They have to correct all grammatical errors and let the correct ones be. There are 20 numbers with answer key, all in two pages.
Hopefully very helpful.
