Parent Information

Hello parents and guardians. I hope you are well! I just want to briefly explain how students will be learning math during our school closure. Every week, the main assignments will be summarized on the advisory "punchlist". Students will also receive detailed instructions and submit work on an online journal platform called Seesaw. By the end of the semester, they will create an online journal.

If you would like to stay updated on our math work, please send me your email address or phone number, whichever you check most frequently. My email address is lawrence.teng@ousd.org. and my phone number is 510-374-0259. I want to support you and our students as best as I can. Thank you!

-Lawrence Teng

Información para padres

Hola padres y tutores. ¡Espero que estés bien! Solo quiero explicar brevemente cómo los estudiantes aprenderán matemáticas durante el cierre de nuestra escuela. Cada semana, las tareas principales se resumirán en la "lista de sugerencias" de asesoramiento. Los estudiantes también recibirán instrucciones detalladas y enviarán trabajo en una plataforma de revista en línea llamada Seesaw. Al final del semestre, crearán un diario en línea.

Si desea mantenerse actualizado sobre nuestro trabajo de matemáticas, envíeme su dirección de correo electrónico o número de teléfono, lo que sea que verifique con más frecuencia. Mi dirección de correo electrónico es lawrence.teng@ousd.org. y mi número de teléfono es 510-374-0259. Quiero apoyarte a ti y a nuestros estudiantes lo mejor que pueda. ¡Gracias!

Math Plan Overview

Welcome back to math learning! I'm excited to support you during this time that school is closed. Every week, you will get the following for math:

  • A checklist of assignments and due dates on your weekly punchlist given through advisory
  • A detailed set of instructions through Seesaw (on Sunday)

For the first week, your detailed instructions will come in an email with subject "Geometry Distance Learning Information". After that, all detailed instructions will come through Seesaw.

Optional Virtual Class Discussion (link in punchlist): Tuesdays 2:30-2:50pm (Huggins)

Optional Virtual Office Hours (link in punchlist): Thursdays 2-3:30pm

(If you cannot make any of these times, email me and we can schedule another time)

How to Learn More Math (Important if you want to do Laney math next year!)

First, review and test yourself on concepts from Algebra I and Geometry that will be important in Algebra 2. There are 13 concepts you should review. Below are instructions for how to find the list of concepts, worked-out examples and practice problems for your review. For each concept, take a picture of your work and upload it to Seesaw. Title it with the name of the concept, and describe what you understand about the concept either verbally or in writing.

  • Visit open-ebooks.cpm.org --> Click I agree --> Scroll down and click the book titled CC Geometry under "High School - Core Connections Traditional Pathway" --> Click "Reference" towards the bottom left of your screen --> Click "Checkpoints" --> Read the note and click the tabs on the top of the screen to go to the different checkpoints. Remember to upload your work to Seesaw!

If you have time and would like to learn more math, such as to prepare for Laney math next year, you can do more math lessons! Do the lessons below in the order they are listed. Read the title and learning goal for the lesson (starts with "Let's..."), and answer the problems for the lesson and the practice set to the best of your ability. I encourage you to work with your classmates online or with me during office hours! Check your answers with the answer key here. Finally, take a picture of your work and upload it to Seesaw. Title it with the name of the lesson, and complete the following sentence verbally or in writing: "The main idea of this lesson is…"

  1. Rigid Transformations in the Plane
  2. Transformations as Functions
  3. Types of Transformations
  4. Distances and Circles
  5. Squares and Circles
  6. Completing the Square
  7. Distances and Parabolas
  8. Equations and Graphs
  9. Equations of Lines
  10. Parallel Lines in the Plane
  11. Perpendicular Lines in the Plane
  12. It’s All on the Line
  13. Intersection Points
  14. Coordinate Proof
  15. Weighted Averages
  16. Weighted Averages in a Triangle
