Intro Activity (3020 min)
Teacher asks the students, have you ever seen train tracks or the edge of a ruler? Those are straight and go on and on. That's what a line looks like in math!”
You can also show things like:

Show lines in the classroom (edge of table, window frames)
Draw this on the board:

For each shape:
Show shape visually.
Count sides and corners.
Ask:Ask: “What does it remind you of?” (Ex: “A triangle looks like a slice of pizza.”)
Draw examples from real life (windows, stop signs, etc.)
