Disciplining a toddler

Hi, my duaghter just turned 2 and I’m having a difficult time with her listening. When I sit to homeschool her older siblings, play a board game or play on the iPad with them. She will pull her sister’s hair, stand on the table, through game pieces on the floor, pretty much ruin our time. I think she’s trying to get attention so I do try to give her some cards or paper and crayons, but of course she’s not able to sit for as long as we do so she will start acting up again 5/ 10 mins later. I explain to her no we don’t pull hair that hurts ( I point to her sister crying and tell her she sad because you pulled her hair) I also say we don’t stand on the table etc. She says ok and I do praise her for saying ok. She will also say sorry sometimes and I do explain that sorry means we are not going to do that again. I’m just not sure if there is anything else I’m missing because it seems like it’s only affective for about 10 mins max. I would greatly appreciate any advice.
Thank you!
