Silly question

My daughter is turning 3 in a few weeks and I plan to start homeschooling her for preschool after her birthday. I’m just curious: do you teach something new daily or is it best weekly? Or do you keep teaching the same thing until they fully understand it? Are there any good resources you can recommend on how to go about teaching? I don’t have high expectations and I plan to teach through play just curious how some go through their day.
