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. We tackle math, science, computer programming, history, art history, economics, and more.

Today Craig finishes up our series on U.S. Government and Politics by talking about both the least and most important aspect of government: foreign policy. Foreign policy is important because it has the potential to affect the largest number of people, but at the same time, it tends to play a minimal role in our perception of the government (unless we’re at war). Foreign policy addresses diplomacy, security, human rights, economics, and the environment at a global scale, and we’re going to talk about how our government has approached each of these policies in the past and which it tends to hold most important. As with all things political, the decisions made in fulfilling these policies can be pretty controversial, especially when considering that the President often has the last word in these issues.
We hope this series has helped you better understand the way the U.S. government works and hopefully encouraged you to participate in the political process - here or wherever you may live. Thank you so much for watching!

This 3D animation explains the hormonal changes during the menstrual cycle. The menstrual cycle begins with menstrual bleeding, marking the follicular phase’s first day. When the follicular phase begins, levels of estrogen and progesterone are low. As a result, the top layers of the uterus’s thickened lining break down and are shed, and menstrual bleeding occurs.
About this time, the pituitary gland starts sending follicle-stimulating hormone to your ovaries, stimulating the development of 5 to 20 follicles in the ovaries. Each follicle contains an immature egg and produces estrogen. One follicle will soon begin to grow faster than others. This is called the dominant follicle. As the follicle grows, the levels of estrogen in the blood rise significantly. This increase in estrogen begins to inhibit the secretion of the follicle-stimulating hormone. The fall in follicle-stimulating hormone allows smaller follicles to die off. They are, in effect, "starved" of follicle-stimulating hormone.
The increasing amount of estrogen in your body also ensures that the lining of your womb thickens with nutrients and blood. This is so that if you do get pregnant, the fertilized egg will have everything it needs to grow.
The ovulatory phase begins with a rise in the levels of luteinizing hormone and follicle-stimulating hormone. The surge in the luteinizing hormone triggers one of the most prominent follicles to pop open and release its egg, which heads into the fallopian tube and starts its journey toward the uterus. Ovulation usually occurs 16 to 32 hours after the beginning of the surge, around day 14 of the menstrual cycle.
During the luteal phase, the levels of the luteinizing hormone and follicle-stimulating hormone decrease. The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces estrogen and progesterone, which cause the lining of the uterus to thicken even more. If an egg is fertilized, progesterone supports early pregnancy. But if no fertilization occurs, the corpus luteum will break down between 9 and 11 days after ovulation. This results in a drop in estrogen and progesterone levels, bringing us back to the first stage of menstruation if no pregnancy has occurred.

This animation teaches the learner to define, identify a noun clause in given sentences. It also teaches the learner how to use noun clause as subject of a verb, as object of a verb, as object of a participle, as object of an infinitive, as object of a preposition, as complement of a verb of incomplete predication, as adjective complement, in apposition to a noun or pronoun. And the leaner can also learn to identify noun clause as subject of a verb, as object of a verb, as object of a participle, as object of an infinitive, as object of a preposition, as a complement of a verb of incomplete predication, as an adjective complement, in apposition to a noun or pronoun in given sentences.

In this video, I will show you how to round decimals to the nearest hundredth. First, you need to identify the hundredth place value which is 2 to the right of the decimal. Next, look at the number next to the hundredth place on the right. If that number is 5 or greater, then you round up the hundredth place to the next digit. If it is 4 or less, you round down (which means keep it the same).

Improved math is a channel created to provide additional instruction on essential math concepts. I’m passionate about math and I know first-hand how important math concepts are in the real world.
Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.
The library of math tutorials that I create can also be used as supplemental instructional material for homeschool math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.
I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.
Improved math is creating more videos every day to cover topics from 4th grade, 5th grade, 6th grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!
Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.
Thanks for watching my channel.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!
