What else to teach?

What are you doing to expand your child’s mind? My daughter can say numbers (and value of numbers ex: one means small amount while ten is a bigger amount), letters, animal sounds, body parts, she does know her colors her favorite is purple. I’m trying to expand her mind by reading since I’m doing my masters in education and I am super busy. But I don’t want to stop her from learning. I know she loves arts (we color every other day), puzzles and music playing since she loves to play the piano and drums. She’s not that sporty but we did buy her outdoor toys😂 at this point I don’t want to push her a lot into learning other things but I don’t want to stop her from learning. We also let her help with house chores (vacuum/laundry) and cooking. She does play pretend with her dolls but I need more activities. Some that are easy clean up, and can keep her entertained she can sit doing something for 30-1 hour. She does swim once a week and we are on wait list for gymnastics and dance class. Btw she’s an only child so we try to keep her busy. Also potty training is already in the process. Thank you in advance! I’m just at a point where I want to know what other children her age know and how I can help her grow.
