Hello friends, one of the most difficult lessons children learn is the difference between circumference and circle; but it is one of the funniest to teach.

"CIRCUMFERENCE AND CIRCLE"

Edited images, Sources 1 2

We ask the children to observe both images well and tell the difference between them.

The circumference, is a closed curved line where all points are at the same distance from a point called the center.

The circle, is the plane figure formed by the circumference and its inner region.

Let's look at the elements that form a circle and a circle

Both the circles and the circles have different elements, one is the radius.

RADIUS

• It is the distance between the center and any point of a circumference.
  

DIAMETER

• It is a string that passes through the center of the circumference. The length of the diameter is twice that of the radius.
  

A circunference and a circle have many diameters.

Arc

• It is the part of a circumference between any two points.
  

Rope

• Is the segment that joins two points in a circle without passing through the center.
  

Therefore, a circle has many ropes that can serve to make many flat figures.

There are many activities where children can be taught the difference between the circumference and the circle.

• One of these activities is to make many circumferences with children and then paint, have fun while they learn.
