Esteemed Parents and Family Members,

We hope this letter finds you safe and healthy amid this uneasy time of COVID-19. As always, our priority is

the safety and welfare of our students. Our 2020 summer program will continue by utilizing virtual learning

platforms and will begin on June 1 and end on June 18, 2020. The purpose of the summer program is to

provide students the opportunity to gain credit for the course your student has failed.

You have received this summer 2020 instructional packet for your (9th - 12th grade) student. This instructional

packet includes materials for the core area(s) your student has failed.

We ask that you contact your student’s school to:

• give you the failing subject area(s)

• give you your student’s summer teachers’ name and contact information / email address

• update any contact information including any changes and additional contact numbers, and

email addresses, etc.

• receive login information for the digital platform

The platform utilized this summer will be:

• 9th -12th Google Classroom

(Download Google Classroom app or access through the Clever Portal)

Our sincere hope is that your child will participate and take advantage of this opportunity for promotion that

will greatly support your child’s area(s) of educational need.

Please encourage your student to read, watch educational programs, and practice their writing and speaking

skills. This is also a great time to share family stories and traditions, play board games and enjoy family time.

As always, it is an honor to continue to serve you and we value your family's commitment in entrusting us with

your child's education.

Estimados Padres y Miembros de Familia,

Esperamos que esta carta le encuentre a buen resguardo y en buena salud durante estos días difíciles del

COVID-19. Como siempre, nuestra prioridad es la seguridad y el bienestar de nuestros estudiantes. Nuestro

programa de verano 2020 continuará utilizando plataformas de aprendizaje virtuales y comenzará el 1 de junio

y terminará el 18 de junio de 2020. El propósito del programa de verano es proporcionar a los estudiantes que

no fueron promovidos al siguiente grado, una oportunidad para obtener la promoción.

Con el fin de trabajar en la promoción de su hijo/a al siguiente grado, usted ha recibido un paquete de

instrucción para el verano del 2020 para su hijo/a de preparatoria. Dicho paquete incluye materiales para la(s)

asignatura(s) que su hijo/a reprobó.

Le pedimos que se ponga en contacto con la escuela de su hijo/a para:

• darle el área(s) de materia(s) que está reprobando.

• darle el nombre del maestro/a de verano de su hijo/a y su correo electrónico

• actualizar cualquier información de contacto, incluyendo cualquier cambio y números

de contacto adicionales, y correo electrónico, etc.

• recibir la información para conectarse a las plataformas digitales

La siguiente plataforma virtual se utilizará este verano para la preparatoria:

• Google Classroom

(Descargar aplicación de Google Classroom o usar el portal de Clever)

Esperamos sinceramente que su hijo/a participe y aproveche esta oportunidad de promoción que apoyará en

gran medida las áreas de su necesidad educativa.

Anime a sus hijos/as a leer, ver programas educativos y practicar sus habilidades para escribir y hablar. Este es

también un gran momento para compartir historias y tradiciones familiares, jugar juegos de mesa y disfrutar

del tiempo en familia.

Como siempre, es un honor continuar sirviéndole y valoramos nuestro compromiso con su familia al

confiarnos la educación de su hijo/a.
