My plan is a combined Math block and a combined MLB, where they each contribute pages to the topics. This will be less lesson planning for me and will give plenty of time for holiday decorating, present making, baking, and family visits. Our topics are Fractions, Graphing, and Practical Applications of Arithmetic. Leah is very excited! She actually lay down on her bed and kicked her feet in the air. Why? Because she adores Coordinate Graphing above all things. Some good resources for this are the Descartes (Stay-in-Bed Scholar) story from Mathematicians are People, Too and the beautiful wooden Coordinate Graphing Montessori material by Clocca Concepts. We had this at my last school but, obviously, can't afford it as homeschoolers. Still, I recommend it highly in case you are looking for just such a thing.
Knowing that Natalie MUST have a three day rhythm allotted to her, or she will take it by sheer force of will and I will simply stand around and pull my hair out trying to move the immovable (remember, our children's traits are gifts given to them by their guardian angel and will stand them in good stead later in life... we just can't see that now), I can see time for 6 stories. Descartes and the fly on the ceiling is obviously one of them. What should be the other five? Hmmm.
