It's such an interesting question..where to start. At their age, it depends a bit on what you want to accomplish. My son is 2.5 and I do play-based learning with him through-out the day. You can read about some of it in my blog -

I typically have a theme for the week and work activities, outings and so forth around that theme. This week is birds. We've recently made two trips to the zoo, so we'll review the pictures and discuss those birds, we'll go to a pet store to see more birds. I'm creating a sheet for him of our common birds in the back yard and we'll make bird feeders and watch for birds. I'll give him a bin with bird seed and a funnel, spoon, cup and toys for him to have as his sensory tub. Of course we'll be on YouTube looking up our common birds and other birds that interest him (like Ostrich) to watch them move and hear them sing. Our letter of the week is N n. While he knows his letters and sounds and is sounding out words, I still keep doing a letter of the week. We'll run around the house and fill a box with N sounding words. etc. We'll do art, read books, re-inact, sing songs, read poems, and more.
Just play based learning. While I realize many people so much, much more, I've come to peace with the reality of what I'm able to do and do well with my son. He's learning and we're having a great time. Our days go by quickly because we're having so much fun.
Oh, as another thought, one of my friends attends a HomeSchooling support team through her local church. While she doesn't attend that church, she goes there for their homeschooling idea meetings. You might investigate that if you want to connect with a group, or looking for some personal support!
I really hope some of this was helpful to you.
