Jen had a good question about how to handle school with all the children in the family. I will try to explain how I do it and what plans I have for next year.
Sam and Nate are only year apart in age and they would normally be in two different grades (Sam second grade and Nate first grade). Emma just turned three so I am not so worried about her. I have always done the same grade with both of my boys. I know families who's children are three grades apart and still they do same curriculum for all of them.
Bible, History, Geography, Read Alouds and Science are same grade (second) for both of my boys. I highly recommend this so you do not get overwhelmed with too much work. Nate has no problems. However, Language arts and Math I keep Nate at his age level. It works out great for them and for me. (Anything extra the boys do they do together at a same level like typing on the PC, or crafts etc.)
(This year I put a puzzle piece on the wall for each book we read during our school time.) For next year I am planing to start with Emma as well. I will keep her at her level (but keep in mind that Jordan will be with Emma in the same grade like Sam and Nate are at some point) The girls are two years apart and again I am planing to separate Language Arts and Math. Anything else they will do the same. Since Sam and Nate are doing great reading I am planing on keeping them involved with the girls. They already read to the girls on their own so the girls reading will become part of Sam and Nate school work (under my watchful eye).
(This is my basket with school stuff for the next day. I get ready for each day after we are done with school work. I do look over the whole curriculum in the beginning of the year to get the idea but I do get ready every day for the next day.)As for Jordan and Emma during our school time right now it is their free time to play (just remember to close ALL bathroom doors and keep all pens and pencils and crayons and markers out of the reach of little fingers unless you would like to have drawings all over your walls). I do have a basket just for the girls with stuff for them to do. They are allowed to use it only during school time and it is fun for them (mostly for Emma at this age). There are plenty of web sites and blogs with ideas for little children. I have to admit that at this point it just looks too much extra work for me.
I hope this helps some of you. As you can see I am planing on doing two different grades for my kids (boys and girls). Then again the word 'flexible' keeps popping in my head so keep that in mind as well :)
On another note we are in full swing with ski lessons. The boys are doing so great this year. Both Sam and Nate are having fun on the big hill and they cannot wait to go with Dad during the week. Jo is not interested at all and she doesn't like the cold weather. On the other hand Emma keeps shouting every day that she wants to ski as well. She will get a taste later with Fil and then we will see (it has been a long time since I skied. Looks like I will have to wait until Jordan gets interested and then we can all go).

Poor Jordan. It got cold this Monday during ski lessons and her eyes were so watery. She just wanted to stay inside and eat snacks the whole time (and climb up and down the stairs).
