Root words and word endings

I am learning to identify root words and their different endings. I had to circle the ending of the words. The ending of “looking” is “ing”. Other word endings I can see in my reader are “ed”, “er” and “s”. I am proud of how I circled the endings of the words. It is tricky to circle the ending and not the other letters.

Zain: It was tricky circling the ending on the computer.
