For Matty (age 9) and Molly (age 5) together:
Story of the World, volume 2
various read-alouds and audio selections to complement our studies in these areas. We especially like recordings by Jim Weiss, who also reads in the Story of the World audio collection.
Math Mammoth 4A and 4B
Writing with Ease 2
MegaWords, volume 1
Getty-Dubay Italic handwriting book C (and soon D)
Math Mammoth 1A
Explode the Code book 2
Getty-Dubay Italic handwriting book A and soon B
We also make lap books, which incorporates a lot of research, writing and planning skills. I find this to be a very useful tool for synthesizing information, as well as practicing good summarizing skills, good handwriting, and also incorporates a creative / graphic layout element to the final project.
Story of the World is a continual HIT in our household. Everyone likes it, not just the students. We listen to it obsessively in the car, wherever and whenever we go somewhere, no matter how short the ride, and when we need to review a point we pull out the books at home. I use primarily the audio recordings, because it helps to fill in the gaps and expand on points that the CC history memory work leaves open. It also helps to give that context which is lacking in the memory work, which my rising dialectic-stage son needs. (He is the question-man...it can be exhausting.)
Math Mammoth is another shining star in our curriculum. I find that (for us) this program just. makes. sense. I love how Maria Miller, the author, incorporates thinking strategies and mental math in every operation that is taught. It is very affordable, and does not include a lot of extras that must be purchased. I can use whatever I have on hand to teach a point, and can trust that each point is taught thoroughly, almost to the point of exhaustion for my boy, sometimes. I will sometimes have to work through some of the more challenging lessons with him, but thankfully, Dad has stepped in and seems to have a real knack for explaining math to the kids...so I LET HIM.
Apologia Astronomy is the third book we've done in Apologia's Young Explorer series by Jeannie Fulbright. We like it--the writing in this particular volume is a little "young" for Matty, but good for Molly. He is getting plenty out of it, though, and it is great for Molly to feel like she's really understanding the science that we're covering. It works well for us right now, because we are currently covering Astronomy as the science topic in CC, as well.
