my teacher tells me to improve my handwriting but I don't know what she is talking about. Could you clarify? Thank you
Handwriting is writing by hand (with a pencil on a piece of paper)! You have to either write in cursive or in print letters, depending on what your teacher wants.
One tip I can give you would be to try to write less quickly, being careful to form each letter correctly. You can practice by transcribing sentences in a notebook, or by filling in specialized exercise books. Also make sure you hold your pencil securely; if you are not sure, you can ask your teacher to check.
There you go :)
I hope it helps you!
