I had a request to add on to my possessive pronoun "his" and "her" sort, so the wish was granted! I just added a "their" activity to my TpT store, which you can get HERE!
It looks similar to the other sort. See an example below:
I also included a "their" visual with a reminder of when we use "their."
I also thought that it would be a good idea to bundle these together and offer it to any new followers who may want all three at once, which you can get HERE. It includes all the same pictures as the originals and you save $1.00.
