Right now, I am teaching my 3rd graders all these grammatical rules...we just finished an unit on possessive pronouns. Whoa! Talk about confusing a few people even myself! Ha!
English rules are very complex. My students are starting to get the hang of it so hopefully, next year they will be able to use and apply those rules while writing.
If there is a website with the proper signs for all these English rules, pls let me know!
I tend to fingerspell pronoun, adjectives, adverbs and sign noun, verbs, possessive nouns, and proper nouns. As for the other rules, I probably would fingerspell them.
