Grade 6th on Khan Academy: By the 6th grade, you're becoming a sophisticated mathemagician. You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data! (Content was selected for this grade level based on a typical curriculum in the United States.)

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.

Your Community | Types of Community | Kids Academy

Your Community | Types of Community | Kids Academy
Does your kid know about the community? Do you know how to explain it to them? Well, don’t worry this tutorial will help you explain the concept of community to your kid in simple and easy words.

What is a community?

A community is a place where people live together. They interact with each other and live by knowing each other. It is very important for the kid to understand the importance of living in a community and what is the actual meaning of living in a community.

Types of communities

There are many different types of communities. In this lesson, we will cover the three most common types.

1. Urban
2. Suburban
3. Rural

Urban community

An urban community is large and highly populated. This means that a big number of people live there. Tall buildings, skyscrapers, heavy traffic, and transportation are key identification of an urban community. For example, New York City is an urban community. In urban communities, you will find everyone busy with their tasks, with heavy traffic and a lot of hustle and bustle. That is why New York is called the city that never sleeps.

It remains busy all day and all night. Most people living in apartment buildings while very few live in homes. You will see a lot of apartments and homes packed with each other due to the high population.

Suburban community

A suburban community is located near a city but not as populated as an urban community. There are less traffic and smaller buildings. Some people travel to the nearby urban for work, which is called commuting. Many people live in homes which are very beautifully made. They have amenities such as large backyards and garages.

Rural community

A rural community has very few people and buildings. It mainly consists of farmland. There is more nature in the rural community, you will see animals, trees, grassy lands, and pure water. people live in small houses that are spaced far apart even miles away. It has a very peaceful environment with no honking and people rushing and heavy traffic.

So, this was a small lesson on communities. In which community would you like to live?

Hi! I’m Laura, homeschooling mom to three. I’m excited to share our homeschooling journey with you. We tend to follow a child led unit study approach to homeschooling. While I pull from many educational philosophies, if I had to pick one way to describe our homeschool, it would be Braveschooling (based on Julie Bogart's book "Brave Learner"). The thing about home education though, is that each family and life stage are so different. No two homeschools look the same. My hope is that by sharing my journey, I can offer support, encouragement, and inspiration to help you think outside the box to create a dynamic homeschool experience tailored to your family.

“Therefore encourage one another and build up one another, just as you also are doing.” ~1Thessalonians 5:11

The human immune system is the most complex biological system we know, after the human brain, and yet, most of us never learn how it works. Or what it is. Your immune System consists of hundreds of tiny and two large organs, it has its own transport network spread throughout your body. Every day it makes hundreds of billions of fresh cells.

It is not some sort of abstract entity. Your immune system is YOU. Your biology protecting you from the billions of microorganisms that want to consume you and from your own perverted cells that turn into cancer. It's so manifold that it is impossible to cover in one video, so we’ll make a series looking at different aspects of it.

Today, what happens when your body is invaded and your first lines of defenses are engaged in a fight for life and death?

Keep going! Check out the next lesson and practice what you’re learning:
https://www.khanacademy.org/hu....manities/grammar/syn

A relative pronoun is a word like “that” or “which” or “who”, so a relative clause is a clause that begins with a relative pronoun. In the sentence “The dragon who breathed blue fire has retired,” “who breathed blue fire” is a relative clause. Learn more about these constructions by watching the video!

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

World history on Khan Academy: Called the Great War (before World War II came about), World War I was the bloody wake-up call that humanity was entering into a new stage of civilization. Really the defining conflict that took Europe from 19th Century Imperial states that saw heroism in war into a modern shape. Unfortunately, it had to go through World War II as well (that some would argue was due to imbalances created by World War I).

Our European history is going to start around 1500 with the Renaissance, but believe it or not, that is not the actual beginning of history in the continent. So, today, we're going to teach you the broad outlines of the so-called Middle Ages, and look at events like the Black Plague, the Hundred Years War, and the Western Schism of the Catholic Church that set the stage for the history of modern Europe.
