Geometry: Point, Line, Surface, Solid


Kal-El wants to learn all about lines, line segments, and rays.  The first presentation he needed in that series was on points, lines, surfaces, and solids.  This presentation is traditionally done with the golden beads.  I wrote labels in front of the boys and we practiced using three-period lessons until the labels were no longer needed.  We took turns carrying the beads to the opposite end of the house so that we could observe that the individual beads "disappear" at a distance.  We also examined them close-up so we could observe that the line is constructed from points, surfaces are constructed from lines, and solids are constructed from surfaces.  


Next, we wanted to record the definitions.  Kal-El was kind enough to look them up in our dictionary.  The definitions weren't as "geometric" as we wished, so we looked them up on Math is Fun and I wrote the definitions on the back of the index card labels.


I put all of this temporarily on a tray because I have a feeling Me Too will reexamine it all later.  This work "unlocked" four new command cards from our geometry command card collection.  I realize I need to blog about those yet, so stay tuned!

  1. I am curious what got him interested in this? Do you try and get their curiosity up some way? Is this KotU? or something you came up with on your own? Sorry for the barrage of questions. :) Just trying to understand how you make all the magic work so I can better inspire my own.

    1. Both kids have an Evan-Moor "Basic Math Skills" workbook that is NOT a school thing. We call them their "math puzzle books" and they do them for fun outside of school hours...for them it's kind-of like a crossword puzzle or word search book. The books have lot of pages that turn math into mazes, hidden-picture pages, etc.,

      The geometry section is Kal-El's favorite section of his book and one of the recent puzzles had him create "line segments" by connecting specific named points that eventually revealed an intricate pirate ship. I taught him about line segments, line segment labeling, and points a little bit to do that page. The next page has rays, lines, and line segments and I told him he needed a few school lessons before he could do that page. That is what stimulated his interest and why he's asking for these specific geometry lessons.

      I am using the Mid-America Montessori album for Geometry. I'll be sprinkling in KotU and Cultivating Dharma, but something about the Mid-America album appeals to me for this particular topic. I think it is the way it approaches what AMI would call "remedial" geometry (which we need) from a truly elementary perspective. I also like the amount of hands-on experiments it uses to introduce multiple geometry concepts. It also does a good job of helping you connect geometry to your other math (using the golden beads in this instance) and to other subjects (it will occasionally suggest writing your new definition and labeling it with the grammar symbols and such). It also had photocopies of all the Albanesi command cards for geometry and tells you specifically in the album when you've unlocked a certain number of them.

  2. Thanks so much! I will look into MAM as we need remedial Geometry as well. Coming from traditional homeschooling I was disappointed to find how many hands on lessons they have missed. Also the Math book sounds like something my boys would like as well.

      This should help.

  3. We are doing something similar to0, except we are starting way at the beginning with the story of geometry. Our geometry studies were influenced with the Beast Academy books. D (7) is loving it this time. We had a round of these stories before but did not keep her interest. Now that we are discovering similar concepts, comic book style in Beast Academy, these stories have sparked new interests in her.
