Curso de Geometría en Curso - Clase de Matemáticas de 9.º y 10.º Grado de Secundaria

This is a 9th / 10th Grade Geometry ongoing class where students can choose which classes to attend without committing to a full semester.  Students need to have taken Algebra 1, learned basics of geometry (properties of polygons, circles, lines and angle relationships)  and possess a solid basic math foundation (e.g. order of operations, fraction and decimal handling, inverse operations, factoring) before taking this class.  It is geared for students entering 9th grade.  It is also be useful for advanced students entering 8th grade and for those who need a refresher of 9th grade math or Geometry.   Students need to have a solid basic math foundation (such as arithmetic, order of operations, fractions) and prior knowledge on the classes they are interested in taking.   

Please Note: if you are joining the class after the class has started, please take a look at the schedule below and make sure you are proficient at the topics before the class you will be joining.  We will not have time to review any materials covered during previous classes as each class is a different topic. Math is built on steps.  If you miss an earlier step, you can stumble in a future topic.   You can join at any time as every week will be a separate topic from previous classes.  So, you can join this class as a full 9th grade Geometry math curriculum or you can join during a week we are doing a topic you might need a refresher on and you can unsubscribe at any time. 
 
You will be charged weekly. First payment will be the day you sign up and then you will be charged every Sunday. You can sign up and unsubscribe from the class at any time. This is an ongoing class so if you need to unsubscribe or pause the class, please do so by the Saturday night before the class you are unable to attend. You can take this class every week or drop in on certain topics if you are paying weekly. This class is a full year of 9th / 10th Grade Geometry Math if you start the class from the first day.

We will be using a website ‘Classkick’ for our classes. You will not need to sign up for an account. I will provide a link at the beginning of each class. When you click on the link, it will ask you to put in a name. You will only need to put in the students first name so that I can identify their work. Classkick is an interactive site where students can work on their math problems on the screen and at the same time, I (the teacher) will be able to see what they are doing on their end on my own screen. Each class assignment is a PDF that is uploaded into Classkick. We will not be watching any videos or using any reference websites during class. To be Coppa Compliant, the class assignment will only be accessible during our class. Once the class ends, you will no longer have access to the lesson. I will post a PDF of the answers to the problems we do in class in the Outschool Classroom for students who want to review the work. I post the answer keys at the end of each week. Sometimes, we will use Kahoot or Blooket to play games on the topic we are doing in class (if time permits). You will not need to sign up for an account with Kahoot, Blooket, or Gimkit. 
 
This is not a graded class but I will be providing optional homework after each class for those who want/need extra practice. Optional homework assignments will be posted in the Outschool Classroom once a week. I will post the assignments and the answer keys so you can check your work when you are done with the assignments. Although homework is not sent in for grading, please feel free to message me on Outschool Messages at any time with questions about the optional homework or any topics we cover in class so that you don’t fall behind. The optional homework will be in the form of a PDF. You will need to print it, do the work, and check your answers with the provided answer keys. There are no tests in this class. No grades will be provided. Optional homework is highly recommended for you to master the topics learned in class. 

All states and countries have their own requirements so please check your requirements to make sure the topics covered in this class is sufficient. 

All optional homework assignments, homework answer keys, and classwork answer keys will be posted in the Outschool Classroom at the end of the week. I will provide you with a link to a shared Google Drive folder where all the homework assignments and answer keys will be uploaded to. 

I operate by the classic "I teach, do guided practice, then independent practice" with checks for understanding sprinkled throughout. Asking students to explain their responses or how they arrived at their solutions is one of my go-to's to gauge learning. I welcome students to ask questions or for help during and between classes!  
I welcome inquires from parents asking to let them know of their child's progress.
