What do I need to know to successfully home school a 2nd and 4th grader? 
I am a full-time working mom who works from home.  We are starting with a Christian umbrella school to homeschool and I am really excited to have the opportunity to do this for my children. 

I'd like some tips on lesson plans, suggested work load, and sites to get curriculum from.  So far I have found some websites to get their papers off of, as the internet will be the major source of where I get their work, but I'm sure there are some good free pages I have not found yet. 

Some moms write detailed lesson plans.  I write out very general monthly lesson plans and I find that they are helpful and that is enough for me.  I always do mine in the summer and type them up for the whole year.  Here is a link for a free online lesson planner, scheduler, and tracker:

Here are two links where you can look at a scope and sequence.  This will tell you what they need to know for their grade level.  You can use it as a guide.  I think these will be especially helpful if you will be using the internet a lot. 

(Two children have already graduated college, two in college, and my youngest 15, is finishing college physics. ) 

**We also used a the writing curriculum to teach our children be creative and learn how write great papers, which has helped them in High school as well as College!  There is also an essay course that goes along with it that was extremely helpful.
