I homeschooled for the first year, this year. I did Pre-K with my oldest. He is "old" for his grade, but didnt meet the age cut-off for Kindy this past year. I didnt' want him to go to preschool 20 hours a week...that is just too much, IMO. I love our preschool, but it is a 5 day program and no exceptions.
So I kept him home and talked with other hoeschooling friends. I decided against a formal curriculum that you can buy, like Abeka, and formatted our goals based upon kindergarten skills. I bouht workbooks, lined paper, craft supplies, etc. I keep free worksheets online and make up a lot of my own stuff. Each week we have a letter and practice writing that letter, making a page in our alphabet book and doing activities related to that letter. Each week we also have a "theme" like counting 1-5, writing those numbers etc. Or a recent theme was "money" so we did lots of things related to that.
For young kids, keep it fun and fast paced! Try not to "hover" and stare at them expectantly. LOL But I do create Lesson Plans to keep it consistent, in general, and know that over the course of the year we are hitting all the requirements.
