In this N5 Grammar video, I go over how to use the structures nisuru, kusuru, ninaru, and kunaru. にする (nisuru) and くする (kusuru) are two structures you can use to talk about making a change to something. This is how you can say 'make it bigger' in Japanese. になる (ninaru) and くなる (kunaru) can be used to talk about a change that has happened to something.
Do you know a fellow student that is interested in Japanese? I'm sure he or she would love it if you sent them a link to this video and helped them out.
