Constructing & Visualizing Radians
Materials:
Paper plates or circles (1 per student)
Pre-cut string (radius length)
Rulers
Markers/pens
Checklist
I measured and marked the radius with string.
I labeled each radian position up to 2π.
I labeled key positions (π/2, π, 3π/2, 2π).
I know what the angle of 1 radian is.
I can explain what 1 radian means.
