Here’s a website that provides grammar worksheets and rules handouts called ABCTeach.com. I was especially impressed with one worksheet which mixed the classic Alice In Wonderland with choosing the correct usage of the pronoun she/her.
Here’s the pronoun exercise:

SHE or HER??
SHE is a pronoun, used to represent a female person or animal that has
already been mentioned.
• Susan was tired. SHE wanted to sleep.
HER is the possessive form of she. It is also used as the object of a verb
and as the object of a preposition.
• The book is Susan’s. It is HERS (possessive).
• Give HER the book (object of a verb).
• Give it to HER (object of a preposition).
The following text is from
“Chapter 1: Down the Rabbit-Hole”, from Alice’s Adventures in Wonderland
by Lewis Carroll
Circle the most suitable word.
Alice was beginning to get very tired of sitting by she/her sister on the bank, and of having nothing to do: once or twice she/her had peeped into the book she/her sister was reading, but it had no pictures or conversations in it, `and what is the use of a book,’ thought Alice `without pictures or conversation?’ So she/her was considering in she/her own mind (as well as she/her could, for the hot day made she/her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her. There was nothing so VERY remarkable in that; nor did Alice think it so VERY much out of the way to hear the Rabbit say to itself, `Oh dear! Oh dear! I shall be late!’ (when she/her thought it over afterwards, it occurred to she/her that she/her ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually TOOK A WATCH OUT OF ITS WAISTCOAT- POCKET, and looked at it, and then hurried on, Alice started to she/her feet, for it flashed across she/her mind that she/her had never before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she/her ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge. In another moment down went Alice after it, never once considering how in the world she/her was to get out again. The rabbit-hole went straight on like a tunnel for some way, and then dipped suddenly down, so suddenly that Alice had not a moment to think about stopping
herself before she/her found herself falling down a very deep well.
