**DECEMBER 2018**

In our next unit, students will learn to understand and use the term “circle” to mean the set of points that are equally distant from a point called the “center.” They will gain an understanding of why the circumference of a circle is proportional to its diameter, with constant of proportionality π. They will see informal derivations of the fact that the area of a circle is equal to π times the square of its radius. Students use the relationships of circumference, radius, diameter, and area of a circle to solve abstract and real-world problems that involve calculating lengths and areas, expressing these in terms of π or using appropriate approximations of π to express them numerically.

Our study of circles continues to support the Standards of Mathematical Practice (MP). The unit begins with activities designed to help students come to a more precise understanding of the characteristics of a circle (MP6): a “circle” is the set of points that are equally distant from a point called the “center”; the diameter of a circle is a line segment that passes through its center with endpoints on the circle; the radius is a line segment with one endpoint on the circle and one endpoint at the center. Students identify these characteristics in a variety of contexts (MP2). They will use compasses to draw circles with given diameters or radii, and to copy designs that involve circles. Using their newly gained familiarity with circumference and diameter, students will measure circular objects, investigating the relationship between measurements of circumference and diameter by making tables and graphs.

I wish all my students and their families peace and love this Christmas season. I am blessed to be part of such a wonderful community at St. Isidore School!

Merry Christmas and Happy New Year!
