The Claritas Publishing memory work guides include memory work in the following subjects:
Scripture
Hymns
English Grammar
Math
Science
History
Geography
Latin
Timeline
At STAR Homeschool Community, we study all of the above subjects except for Latin. The memory work is set to music and gets stuck in the students' (and moms'!) heads.
While Charlotte Mason certainly taught memorization and "recitation," there is debate about whether she would have encouraged rote memory work. My personal belief is that interesting information, memorized with music, cannot hurt a child. I believe that context is incredibly important for memory work, though. Memorizing rote facts without reading any "living books" to explore the information further is dull, boring, and a waste of time.
The GLC reading plans are designed to give context to the memory work. For example, the history sentences are explored in more detail in the history reading. The goal is that children would get some great information in their heads in two ways:
Memorize sentences to music, and
Hear stories about the same information
And hopefully, your child will begin to ask questions, connect concepts, places, people and events in history; and that he will ask questions and have a desire to learn more.
Ideally, a family will go through the Claritas Publishing memory work two or three times in an eight to twelve year span. All of these facts will become like coat hooks hanging on a wall, ready for a piece of information to hang on them. Perhaps your child will be at church and will hear of a place he memorized--suddenly, that imaginary coat hook in his brain will have a piece of context hanging on it. (In addition to all of the context you gave your child by reading "living books" aloud).
