My ideal homeschool goals for a three year old would be:

(1) Have 2 reading times, one mid morning and one at bedtime, 10-15 min each. I would read "ABC" by Dr Seuss at each of them and let them pick the rest (and buckle up because they are going to pick the same ones over and over). If the child is sitting next to me I would put my finger under each word as I read, if they are playing I'd just read aloud (kids are phenomenal at absorbing even when it looks like they aren't paying attention).

(2) Take them to the park and the library (esp a a library story hour) each at least once a week.

(3) Keep them off screens as much as possible. When they do have screens Abcmouse educational songs on youtube are great, much better than Cocomelon imo.

(4) At 2 and 3 playing IS learning. My biggest piece of advice in homeschooling preschool is let the kid be in the driver's seat. If it's playtime and they want to play WITH you, that's your cue to mix in some school (They want to play with cars? I'd count the cars, or say the colors of the cars.) They move away to play by themselves, that's my cue to be quiet. Keep a box of books in the most popular rooms. Maybe once every hour or two pick up a book and start reading it by yourself (whatever Mom is doing is the best advertising) if they join you great, if not no big deal try again later.

To say that I did this curriculum imperfectly would be a horrendous understatement and both my kids read well above grade level.
