Using Esther's post, we discussed how distances travelled by a vehicle are measured by the number of revolutions it makes multiplied by the circumference of the wheels.

Ariel  shared that there is a mechanism that helps to determine the number of revolutions made by car wheels and she is right!

Here's a link to find out more about odometers:

https://en.wikipedia.org/wiki/Odometer

Ms See then showed us a trundle wheel and demonstrated how distance can be measured using the wheel.

Why must we learn circle in primary school and not secondary school or on further education

# data[].attributes.body
I wonder what math questions will be asked about circles

# data[].attributes.body
I think there are building that are semi circle

# data[].attributes.body
It is amazing to find out that the circumference of an object can be longer than the height of the object

# data[].attributes.body
I think we can use circles as car tyres

# data[].attributes.body
I wonder why we have to multiply pi with the diameter to find the circumference

# data[].attributes.body
I wonder how circles is involve in our life,why must we learn circles

# data[].attributes.body
Why is diameter called diameter?

# data[].attributes.body
I think pi was created by a man named William Jones

# data[].attributes.body
I think they will ask us to find the circumference (curvy figure/circle)

# data[].attributes.body
I explore that the area of circle is found using ‘pi’ x radius x radius

I wonder who found this method to find the area and the perimeter of the circle?How did he know that this would allow him to find the correct answer?

# data[].attributes.body
I wonder why pi is equal to 22/7.

How is circle used in our daily life?
