Well, I am going back in history recalling different curriculums we used and for what grade levels. The following is what we did - click on the words in Bold for more information.
Bible - We did individual devotions for this year. God and Me for girls and Gotta Have God for boys. These come in various age levels - was a favorite for my kids and they continued on their own in the summer. Even asked for another book the following year.
Language Arts - My 5th grader did Apologia's Jump In for writing, Getty-Dubay Italic Handwriting, Learning Language Arts through Literature and Building Spelling Skills.
All the kids did the appropriate level of Wordly Wise.
Math - We continued on with the next level of Teaching Textbooks for our oldest. Then we continued with the appropriate level of Horizons math for the other four.
Science - We did the first level of Apologia Zoology. Had a lot of fun with this, as always.
History - This was the pilot year for Girls of American History. We did this along with two other families and had a blast. It was published the end of 2012.
