Ms. Angelica Cassimiro | Physical Education, Grades K — 5

I wholeheartedly believe in the power of the mind body connection. A healthy body fosters a healthy mind. Teaching what I am passionate about is a big gift to me and that is what I share with our students. We will learn fitness concepts, movement skills, muscle groups, nutrition, mindfulness activities and responsible behavior. We engage in a variety of activities and small sided games to put skill into dynamic practice. We focus on practice over results. We prioritize enjoyment of moving our bodies.

I’ve been a dancer and dance therapist for 20 years. I’ve trained and taught gymnastics, yoga, and martial arts. I’m self-taught in house and street dance.

MR. Lonnie Hampton | Music, Grades K — 5

I am the instrumental music teacher at PS20 servicing grades K-5th. Music is once per week with an emphasis on learning to play the following band instruments: clarinet, saxophone, trumpet, trombone, bass, or drums. All classes will work on Rhythm, Reading notated music (1st-5th) and Music theory.

Kindergarteners begin their musical journey with percussion instruments, ukulele, and the violin. They work solely on reading rhythms rather than actual notes during their first year. 1st-5th grade will work on learning to play and read all notated music on their chosen instrument.


Mme. Valerie McIntosh

Mme. Valerie McIntosh | French, Grades 3 — 5

I am one of the two French as a second language teachers at PS20 and I primarily teach Upper Grades (3-5). I see most classes at least twice a week. Students will learn:

  • Dialogue: Basic conversational skills.

  • Grammar: Basic rules of French grammar, with an emphasis on gender and how that affect word structure

  • Poems/Songs will be used to develop vocabulary, rhythm, pronunciation and comprehension.

  • History/Culture: Students will learn about countries in the world where French is spoken and the customs of francophone peoples.

Mr. Andrew Ortner

Mr. Andrew Ortner | French, grades Pk — 2

Bonjour! My name is Andrew Ortner or simply Mr. O. I grew up in the city, but lived in France during the summers in my childhood and later studied in the South of France in high school and college. I teach French as a second language for pre-K through 2nd grades as well as a 4th grade class. My classes engage students in French learning through music, art, and science. This year I will introduce the wonders of the undersea world in the French language through Jacques Cousteau and his works as well as sharing videos of my own diving experiences. We will learn about the delicate environments and how to protect our waters and earth. In doing so, we will practice new vocabulary as well as verbs and adjectives. We will also explore writing and reading in French.

I love to scuba dive, ride my bike, practice yoga, play the drums, and admire my two cats, Cosmo and Poly.

 
 

Ms. Jessica

MS. Jessica | SCIENCE, grades K-5

I am thrilled to be teaching Hydroponics, Science and Sustainability to grades K-5 at PS 20. I've been a teacher for 20 years and an advocate for the environment for as long as I can remember. Students will engage in standards-based lessons on topics such as life cycles, germination, pollination, photosynthesis, the honorable harvest, how to be stewards to our Earth, and so much more. You can look forward to your student(s) proudly bringing home some vegetables that they grew themselves throughout the school year. I am also happy to be serving as PS20's Sustainability Coordinator, to continue and build upon the great work that the school has already done in the areas of recycling, composting, energy conservation, and environmental activism.

As a school we will take part in the DOE Office of Sustainability's Climate Action Days:

  • Energy - December 6th

  • Waste - February 7th

  • Health, Wellness, & Green Space - April 17th

  • Water- June 12th

When I'm not at school you can find me hanging out with my 2 kids, playing with our dog, or going for runs throughout our beautiful city.
