 Welcome back. Now that we have covered why you should use Khan Academy in your classroom, I'm sure you must be excited to know which subjects, courses or curriculum are available at Khan Academy. In India, our focus is on math and science. These subjects are very important to build logical reasoning, critical thinking and problem solving skills among our students. In this video, we will cover what content is available on Khan Academy, its alignment to the state or NCRT curriculum and how our content is structured on our platform. As we shared in our previous videos, Khan Academy is a mastery-based platform. At Khan Academy, we do not want you to worry if the content and its sequence are relevant to the textbook that you and your students are using. So apart from having world-class content, we make sure it is aligned and mapped to your state or NCRT curriculum. We focus on math and science for grades KG to 12th grades. You can go to Khan Academy.org and click on courses on the top left to see all our courses. In India, our content is available in English and in multiple Indian languages including Punjabi, Marathi and Hindi. We have math for classes 1 to 12th and science for classes 9 to 12th available in English. Additionally, we have foundation courses for grades 6 to 10. Suppose you are teaching math for grade 6th. At the beginning of the year, if you see some students struggling with the basics from previous classes, you could have them go through the 6th grade foundation course. Foundation course content can be used as material for remediation to get the students ready for their current grades. What's important for you to note is that all our math content on our English and in the websites is mapped to the NCRT curriculum. All our content in Punjabi and Marathi is mapped to the state curriculum. Now let's look at what each course contains. Let's take class 6 math as an example. Once you end class 6 math, on the left side you can see that the course has been divided into different units. This is similar to the way the index page of the textbook includes the names of the chapters. So, for class 6, we have a unit on whole numbers, playing with numbers and much more. You can also see mastery points. We will talk about this in detail in our advanced course. If we scroll down to the bottom of the page of this course, we will find a course challenge. It has 30 questions from 30 randomly selected exercises in the course. It helps us to understand the progress our students have made by the end of an academic year. It is similar to a final test. Overall for this course, you can see the different topics or lessons that are covered under each unit. For instance, the unit on whole numbers has different lessons. This page will give you a broad overview of the different units and lessons that the course contains. When you click on the topic of associative property, you will see that it comprises two things. Bite-sized instructional videos that can be used to understand the concept and practice exercises to master the lesson. You will also find two additional things, quiz and unit test. Quizzes essentially combine practice questions from all topics that have been studied prior to the quiz. There are typically five to seven questions in a quiz. Unit tests are designed to check for a student's understanding of the entire unit. Typically, a unit test comprises nine to eleven questions from all the topics covered in the unit. Now that we have looked at what is available at Khan Academy, I urge you to apply what you have learned. So here is the task for you. Whichever class you teach, find your course and explore the videos and exercises as a learner just to get a hang of it. So if I am teaching fifth grade math, then my task is to find a grade five math course and explore the videos and exercises just like how your students would do it. You could also ask your family members or ask the children in your family to try it out.
