I'm really impressed that so many people plan months ahead of time. It's summer, and I am just now planning for next year. Here's my tentative plan for my STEM loving soon-to-be 6th grader.
.Language Arts:
Reading: Most of Core Knowledge LA Grade 6 plus middle school level editions of Beowulf, King Arthur legends, Sir Gawain, Canterbury Tales, Saint George and the Dragon, 1001 Arabian Nights. Still looking for a few non-western stories of the Middle Ages era, especially India and China (suggestions welcome!). Free choice reading every day at bedtime.
Spelling & Vocabulary: CKLA Grade 6.
Writing: IEW SS B1. Maybe an occasional assignment from CKLA 6. Outline history 1x/week.
Grammar: CKLA Grade 6 and IEW Fix-it Grammar Robin Hood. Something to supplement with sentence diagramming??
Poetry: Memorization - one per month (ish).
Math: AoPS Pre-Algebra plus Khan Academy.
Science: Continue with Conceptual Integrated Science Exploration. MEL Science Kits. YouTube physics videos.
History/Geography: Middle Ages with focus on science & technology of the era. Curiosity Chronicles - Middle Ages and Early Modern Era part 1. Finish Story of Science: Aristotle Leads the Way by Joy Hakim (and start Newton in the Center). Extra books about science and technology in India, Baghdad, China during Middle Ages.
For. Lang.: Pimsleur Spanish.
Art: Artistic Pursuits.
Music: Classics for Kids.
Logic: The Basics of Critical Thinking.
P.E.: Swim lessons, PE class for homeschoolers at the Y if they offer it this year.
