Now I’m not an anchor chart master but this one worked for us!
To introduce the skill I wrote sentences on strips and placed them in our pocket chart.
I have 13 kids so I wrote 13 sentences. I then gave them each an another strip with a pronoun written on it. As we read aloud each sentence we talked about which pronouns could take the place of the nouns in our sentences. The student who had the card that made sense, came up and placed it over the noun to take its place.
