A Human Graph in Algebra

y = x/2
Eighth graders in Mark Doocey's math class recently used our backyard as a giant co-ordinate plane when they were introduced to graphing linear and quadratic functions. The boys were assigned a value for x and had to move to the correct position on the plane when shown each linear and quadratic function.

By doing so, the boys formed a line or parabola, part of the solution set of the function.

y = (x/2)^2
This exercise allowed the boys to experience how their positions and the shape of the graph changed for different functions, and when each variable of a particular function was altered.

y = 16/x
Giving the boys a way to learn kinesthetically helps them conceptualize the algebra underpinning the concepts that they learn later in the classroom.


Another great aspect to an activity like this is that when the boys realize they aren't "in line" with the group and have to self correct, it provides an opportunity for co-operative learning. Each member of the group is responsible not only for learning what is taught, but also for helping his classmates learn, creating an atmosphere of supportive, collaborative achievement.

An Evening With Lidia Bastianich

On Tuesday evening, Lidia Bastianich, award-winning chef, restaurateur, television host and author, visited Saint David's to speak to the Saint David's Alumni Parent community and current Eighth Grade.



Interviewed by Alumni Parent Dr. Joseph Haddad for our Alumni Parent Council Lecture, Lidia recounted her youth in Istria when the once Italian peninsula shifted to communist reign after World War II, her two years spent as a refugee in Trieste, and her experiences after her family immigrated to America when she was eleven years old.


The boys were fascinated with her discussion about her family's escape from Istria and her life as a refugee and immigrant. She expressed her everlasting gratitude to the people who provided assistance to her family in Trieste and when they first arrived in New York. "I can't talk enough about the goodness of the people who helped us," she said. "I am where I am because of them."

As a highly successful person with…

Navy SEAL Bill Berrien '82 Gives Chapel on Service to Saint David's Boys

Former Navy SEAL and Saint David's Alumnus Bill Berrien '82 fascinated all during his Chapel Talk Tuesday morning to our seventh and eighth graders.

A SEAL for nine years, Bill was a member of two platoons in South America as well as part of a Joint Special Operations unit. He shared his SEAL Trident with the boys, talked about the intensity of training, and noted he remains close to many with whom he served.


Connecting his service to the values that Saint David's espouses, he encouraged the boys to always be students--curious throughout their lives, to find the best in everyone, appreciate setbacks, and to learn from failures. In the video above, he addresses the first.

He closed by planting these "seeds" for our boys to consider: that life is a journey to be embraced broadly with openness to a variety of opportunities; being a service leader is of utmost importance; the unknown should be embraced; and, finally, that the boys be their own best friend, compassi…

Sono arrivati in Italia!

Eighth graders and their teachers have arrived in Rome and are enjoying the first day of the 10-day Italian Study Tour.


Their first stop was St. Paul's Outside the Walls, where Cardinal Harvey, Archpriest of the papal basilica, provided a tour. Later, the boys visited the Spanish Steps, and toured the Pantheon.




Over the next two weeks the boys will visit sites in Rome, Assisi, and Florence. They will see in person the paintings, sculpture, and architecture that they have studied in the interdisciplinary humanities class. Each day their understanding will be deepened as they write about the experience and sketch the various works in their journals.


This trip is an exceptional opportunity for our boys to augment their in-class learning, build experience as citizens of the world beyond New York City, and strengthen their bonds as a graduating class.

I can't wait to join the boys and their teachers later in the week!
