Circle properties

About: 

In this lesson plan students will learn the basics of calculating different measurements of circles. Starting with radius, diameter and circumference, students will view one captioned video and complete activities to confirm their learning. A second captioned video on area and confirmation activities can be followed by a creative session where students devise their own 'problem' and make use of the circle formulas.
