TEKS Math Standard: 5.1.G

display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication

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.

Gr 2-8

Math Curiosity: Legendre’s Conjecture

Gr 3-6
