We started off working today on trying to figure out the bugs, or incorrect ways in the mathematical thinking that our children have. We thought about measuring a line segment & differentiating the lesson based on students at lower level, students at an average level & exceptional students. We thought about different problems that could occur at each level. My students would probably be on the lower level.
Problems That May Occur
-----------------------------
The meaning and the measure of a line.
The differences in ways of measurement (inches, centimeters)
The fact that ome students may start at 1 on the ruler instead of 0 .
What are the lines between each number? ( You have to have a basic understanding to know what each mark is between, especially for the inches)
Solutions
Teaching them about what a ruler looks like and asking them to draw it (at least the 4ths)
Measuring three lines; constructing shapes with those lines. We also discussed fractions.
Other ways for geometry in Second Life
Maybe looking at the hands of a clock, but the turning of the doorknob, the rotation of the moon around the earth, a slice of pizza, angles by the way a door opens.
Tomorrow, I hoep to develop this into more of a concrete lesson.
