In this concept attainment lesson, students try to determine if lines are perpendicular or not
Why tell a kid the rules of a triangle when they can discover them!?
A lesson about lines, line segments, and rays that avoids dull memorization. Instead, we ponder this delightful question: Which is longer, a ray or a line? Then, kids consider what these different geometric concepts would think about each other.
