Curated OER
Calculus
Young scholars make an inquiry with the aid of technology into the concept of functions. The emphasis of the lesson plan is on the interplay between the geometric and analytic information.
Curated OER
THE AREA OF A CIRCLE
Young scholars examine the relationship between circumference and diameter and how to use the formula to find the area of a circle. In this circle lesson students divide into groups and complete an activity.
