Questions about kids in same "grade"

[gfmomma]

I am new to homeschool. This is our first year and I am feeling overwhelmed. My kids are 8 & 7 years old and I also have a 4 year old and a 6 month old. I am thinking I will put my 2 older kiddos in the same "grade". I am thinking Beyond Little Hearts for His Glory or Bigger Hearts would be about the right age group. I was wondering if I needed to order 2 of anything so they both have the right books or workbooks. Any advice would be greatly appreciated. Please help!!

In Beyond, the only things you would want two of are math (at what ever level each one is at) and possibly DITHOR (if both are ready for that).
In Bigger, the same is basically true. You will still need two math workbooks. You will also need two handwriting books. DITHOR again would be two student books if both are ready. And last, Rod and Staff - you probably don't need two unless you plan on them doing more written than oral.
