Participating in my club taught me so much about myself. I was introduced to a part of me that I didn't know was there before. It opened a door to a whole new world.

Sample of Courses Offered

Simply STEM

Come and join our high school science teacher! This course is an introduction to different challenges and experiments related to science, technology, engineering and math. Students will be introduced to coding, environmental science, construction as well as other topics.

Elementary School Math Circle

A math circle is a chance for students to engage with mathematical ideas and problems that are not usually taught in a school setting. Pioneered in the USA by UC Berkeley during the 1980’s, math circles have a rich history of providing students of all ages – sometimes as young as pre-kindergarten – with rich and empowering experiences with real mathematics. The students work with each other and the teacher to collaboratively explore the meaning and solutions to "low floor, high ceiling" problems, questions which are easy to grasp but which can be explored to many levels of depth. This math circle will be specifically modeled after the Berkeley Math Circle’s Elementary 1 program. In this program, the problems are short, fun, hands-on, and designed to foster a confident attitude towards mathematics.

Animal Art

Let's learn about different animals and create them out of art! We will read books about different animals and use images for inspiration. We will make drawings, paintings, prints and sculptures of a variety of animals!

Mandarin Chinese For Kids!

We will be learning some basic Chinese with fun activities. I highly encourage students who participated in Winter ASE to continue joining, but all SK to 2nd graders are welcome! Let's have fun and learn!  

Keep Calm and Shine On!

Only for grades 1 and 2

Join our ES/MS Counselor and her furry friends! The purpose of this course is to help students build confidence in themselves and to help them develop healthy and appropriate social skills.

Boys on the Run - Fitness Addition

Boys On The Run is a fun way to get engaged after school this spring! We will focus on outdoor running and indoor fitness.

Girls on the Run

Back by popular demand! The weather is getting warmer and it's time to lace up our running shoes!

Come join us as we learn life skills such as perseverance, confidence, communication and teamwork through dynamic, interactive lessons and running games. On days when the air quality keeps us indoors, we will make use of the classroom, stairs, yoga studio, and fitness room. 

Put on your running shoes and your girl-boss attitude because on Tuesdays, girls are on the run! New members welcome! 


Origami and Geometry

How can a paper crane be used to learn the concepts of geometry? 

Sure, origami is a fun way to make the class more engaging by appealing to the students’ creative/artistic side while showing them how to ’do mathematics?' with their bare hands.  

Paper folding is an enjoyable activity that helps to develop hand-eye coordination and attention to details, encourages peer support and fosters relationship building. Also it enhances geometrical reasoning and mathematical learning.

Students will have fun while learning many challenging mathematical concepts such as a given number of angles or a given number of equal faces while Identifying triangles, quadrilaterals, pentagons, hexagons, and cubes.

Kid Power

Join our HS Counselor! Kid Power is a fun imaginative after school activity where kids get to act like a senator and debate fun kid friendly topics as they learn to speak on their feet, listen carefully to others and debate their point of view. This is a great opportunity for students to read a non-fiction piece and then speak confidently in front of their peers about their point of view.

Science Trivia Questions and Healthy Eating

Do you love answering Science trivia questions and learn what healthy eating means? Then this ASE is for you! Come and join Mrs. Piscioneri’s class…learn to answer questions related to scientific facts and discoveries while exploring the health benefits of vegetables and fruits recommended by the Dietary Guidelines for Americans published in 2016.
