The student needs to understand that any points on the planar surface of the circle are said to be interior points and points on the outside of circumference are said to be its exterior points.
===Activity No # ===
==='''Notes for teachers'''===
This knowledge is important to understand secant and tangent to the circle.
==='''Activity No #1''' ===
''''''A game of tiger and goat.''''''<br>
Draw a circle on the playground. Make children stand on its circumference. Call one student inside the circle to be a goat and other student on the exterior would be the tiger.
