Hi SherinaW, and welcome to the HOD Board!

Lissiejo did a great job of pointing you in the right direction by having you check out the placement chart - she is really such an encourager and helpful lady. You are right that the guides are grouped by ages instead of grade levels. I love this!

This takes into account each child's needs and moves them forward. HOD is not a "oh, your child is 6 yo, here's your box of stuff" kind of curriculum. HOD does take age into account, but it also helps us consider individual skill levels in various subject areas, whether it is a good idea to combine, how mature dc are, how independent dc are, how dc work together with siblings, size of family, life circumstances, etc. - placement considers all these things - and the result - a customized great placement for each family that isn't cookie-cutter!
So, I am eagerly anticipating hearing about each of your sweet children!

The kinds of things that are helpful to tell ladies on the board are usually in regard to the first page of the placement chart. For your 4.5 yo, you would want to look at the "Little Hands to Heaven" and the "Little Hearts for His Glory" columns of the first page of the placement chart, and tell us about him. For example, in reading, is your ds "still learning letters and letter sounds", or is he "ready for phonics instruction"? For writing, is he "getting ready to write", or is he "ready to begin learning formal manuscript printing to begin to write words"? Just sharing your thoughts in regard to the first page of the placement chart will help all of us chime in with specific placement advice to get you off on the right foot!
Likewise, for your 6 yo dd, you will want to look at the LHFHG and Beyond Little Hearts... columns, and share your findings here. This may seem like a complicated process, but it really is not, and we are all here to help! It may take a little time, but I can guarantee it results in a better school year all year long than a "here's your box" kind of approach.
We have used HOD for 10 years now, and we continue to LOVE it! I am excited for you to begin homeschooling with HOD. The guides are truly open and go, with 2 page spreads that are easy to follow. They are very clear about what to do, and the plans do take into account learning styles, making sure each style is well represented.

The guides make it easy on us moms - I never prepare to teach ahead, and I am using 3 guides.

Please take time to share your placement chart thoughts, and all these super gracious and helpful ladies on this board will chime in to help you out! Looking forward to getting to know you here!
In Christ,
Julie
