Alabama Math Standard: 2.M.A.20

Measure to determine how much longer one object is than another, expressing the length difference of the two objects using standard units of length.

Lines, Line Segments, Rays, and Infinity!

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.
