Dear Girls and Boys,
We are marching on in Geometry and this time we are going to learn everything you DIDN'T want to know about a circle!!! heehee.... So for a review on the circle vocabulary before we start- radius is the line from the center to the circle: diameter is from one point on the circle through the center to the other side; and the circumference is all the way around. But we are learning about the Area of a Circle. So with the foundation of the vocabulary, we build on it with AREA. Area is always the sections inside the circle- AREA is always measured in units squared ( pi times d). Pi is an approximation for the distance around any circle. It is the very famous symbol and it represents approx. 3.14 or 22/7. I am sure you have seen this in your math travels.
We will be looking at a great deal of circles as we have many bird feeders in the classroom to measure to our hearts desire!
As always in MATH,
Mrs M
