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!
