Mathematics: How to Calculate Commission

Learn how to find earnings through commission.

In this video I use three different examples to explain how to calculate total commission, total sales as well as total pay when an employee has both a hourly rate and a commission component of their salary.

I hope it helps :)

View more at www.MathAndScience.com. In this lesson, you will learn how to solve percent problems that you are likely to encounter in everyday situations. A percent is expression a fraction when the denominator is equal to 100. The word "percent" means "per 100". A typical problem might ask that 6 is what percentage of 12. In order to solve this, we need to set up a proportion, where we solve for the numerator of the fraction, which we will then circle as the percentage for our final answer. To solve these problems, we will also learn to solve equations and use the rules of algebra to find the final answer.

What do you know about the history of American Sign Language? Did you know that the man who created it used some French signs? Dr. Thomas Hopkins Gallaudet traveled to France to work with three Frenchmen to develop the signs in an effort to help his neighbor's deaf-mute daughter, Alice. Today, hundreds of thousands of people around the world claim sign language as their primary language!

What do you know about Zeus? Have you ever heard of satyr or centaur? In Greek Mythology for Kids, you will learn about many creatures and important gods and goddesses that the ancient Greeks created. Mythology is basically a way of telling stories. Native Americans, Egyptians, Romans, and many other cultures and religions have created myths. However, Ancient Greek mythology includes some of the most well-known stories.

Ancient Greece is the foundation for most western culture today. It lasted from 800 BC to 146 BC, which is when the Roman conquered Greece. The stories the Greeks developed are very popular, and they helped them explain the world around them. Because they didn't have access to the same level of science and technology that we do today, they couldn't explain natural phenomena like the sun rising and falling every day or the occasional thunderstorm.

To explain thunderstorms, for instance, the Greeks believed there was a god called Zeus that could control thunder and throw lightning bolts down from the sky. All the gods and goddesses had wildly exaggerated personalities and one or more magical powers. They were not considered good or bad. They used their powers for good, trickery, and adventure. Some gods were Titans, some were Olympians, and some were relatives of both.

Apart from the gods and goddesses, the ancient Greeks also came up with other interesting creatures and monsters. Cyclops, for example, was a monster with one eye. A centaur was a creature that was half horse and half man. Similarly, a satyr was half man and half goat. One of the most famous monsters was the gorgon called Medusa. Instead of hair on her head, she had snakes. The myth states that if someone looked directly into her eyes, they would immediately turn into stone.

The Checks and Balances that are in place in the United States are important for kids to understand and in this video we explain how the three branches of government can work together but are also in place to check on each other and make sure that not one branch has too much power.

Separation of power has been important since the United States were formed and In short the constitution states that there are to be three branches of government, and the balance of power between the branches will be equal. The 3 branches include the Legislative, Executive, and Judicial branches. The Legislative branch is made up of the House of Representatives and the Senate make up the Legislative branch. The Executive branch includes the President, Vice-President, and the Cabinet, which is made up of people who give advice to the President such as Secretary of State, Defense, Homeland Security and many others. Finally, the Judicial branch consists of nine judges called justices, and they oversee the United States court system (The Supreme Court).

Each of these branches can keep the other branches in check and to pass any major law or bill these branches must learn to work together. In this video your kids / students will learn how the three branches work independently and together.

In this video we learn all about comets for kids. Students will learn where comets come from, how comets are formed, what comets are made of and many other fun and interesting facts about comets.

We learn that a comet in the outer parts of the Solar System is too small to be seen from Earth. You can think of a comet as a large snowball filled with or covered by dust, metal, and debris. They have an icy core, covered by a layer of black dust. The center is mainly composed of water and gases, frozen and mixed together with bits of rock and metal. The nickname for a comet can be a “dirty snowball”.

When a comet gets closer to the Sun, the ice melts and changes into a gas. Dust particles spread out around the nucleus in a cloud called a coma, and the Sun causes them to glow. The coma of an average comet is sixty thousand miles across, but it is also very thin. Radiation and the solar wind drive the gases of the coma away causing it to form a straight tail. The tail may grow to ninety-million miles in length.

How many active volcanoes do you think there are in the world? What makes a volcano active versus dormant or extinct? In What Is a Volcano? for Kids, you and your students will learn the answers to the questions and more. Plus, you can conduct an experiment where you make your own model volcano!

A volcano is a mountain made from cooled lava, ash, or other material from previous eruptions. Some even exist on the ocean floor. There are over 1500 active volcanoes in the world today. Every day, 15 to 20 volcanoes erupt somewhere. In the United States, there are active volcanoes in Hawaii, Alaska, California, Oregon, and Washington. Movements of the earth's crust cause volcanic eruptions.

What's the difference between magma and lava? Magma is located beneath the earth's surface. It is made of liquid or semi-liquid rock. After gas bubbles inside the magma expand and build up the pressure in the volcano, the volcano erupts. Once the magma escapes the volcano, we call it lava. The more often a volcano erupts, the larger it becomes as the lava cools and builds up the volcano.

Keep watching to follow along with a fun experiment to see how volcanoes work. You can pause the video when prompted to make sure you gather all the necessary supplies (and people). For more detailed instructions, check out the link below to our Earthquakes and Volcanoes STEM lesson plan. Hope you enjoy!

Did you know that carbon is the fourth-most abundant element in the universe? Did you know it also is essential to life on Earth? Every living thing on the earth needs energy to survive. The main source of energy comes from the sun, but only a few living things can use sunlight directly as a source of energy. Animals like us need help. That's where carbon comes in!

Carbon comes in two forms: diamond and graphite. Carbon contributes to the process of photosynthesis to help plants create food and give off oxygen. That oxygen let's us breathe and live. Not to mention, eating those plants provide food to keep us alive as well. Without carbon, there is no photosynthesis. Without photosynthesis there's no food!

The carbon cycle involves the exchange of carbon between organic and inorganic elements. Just like all the earth's cycles, there isn't a starting or ending point. It's a continuous process with several steps. Carbon moves from the atmosphere to plants, from plants to animals, plants and animals to the ground, living things to the atmosphere, fossil fuels to the atmosphere, and the atmosphere to the oceans. That's a lot of steps!

When carbon dioxide releases into the atmosphere, it acts as a greenhouse gas that helps keep the earth warm. However, there's an imbalance to this system, and too much carbon is being released into the atmosphere. Not enough is being absorbed, so Earth is warmer than it should be. There are ways to help slow the effects of climate change though, such as planting more trees and cutting fewer trees down.

We hope you and your student(s) enjoyed learning about this essential element! If you want to learn even more, head over to our website and download one of our many free lesson plans about landforms, full of activities, worksheets, and more!

Do you recognize the story, The Tortoise and the Hare? This story is called a fable. In Fables for Kids, you will learn about this unique type of story and the elements that must be included. Can you think of any of those elements off the top of your head?

All fables have five specific characteristics. They must be fictional, meaning that it is an imaginary story. Generally, these stories are fairly short. The element you probably knew already is that fables teach a moral lesson. "Slow and steady wins the race," for example, is the lesson we learn from The Tortoise and the Hare. In all fables, the main characters are always animals that act like humans. Finally, the setting of a fable is always outside.

Where did fables come from? Aesop, a slave of African decent who lived in ancient Greece, had a collection of fables that we now call Aesop's fables. Historians are still unsure whether he wrote all the stories himself or simply gathered them from other sources. Even though he lived a long time ago, his stories were passed down to the present day!

We hope you and your student(s) enjoyed learning about this special genre of stories! If you want even more practice, head over to our website and download one of our many free lesson plans about reading, full of activities, worksheets, and more!

Have you ever wondered why there are no dinosaurs anymore? In Extinction for Kids, you will learn why dinosaurs no longer roam the planet. You will also learn about some other species that likewise died off. Believe it or not, plants can become extinct too, and the process happens more quickly than it does for animals.

Most of the time, extinction happens over a long period of time. When certain animals can no longer reproduce, they begin to die off. Or when animals can't adapt to their changing environment, this can also lead them to extinction. In cases of mass extinction, many species of plants and animals die out very quickly. Many scientists believe that this is what happened to the dinosaurs and other plants and animals that were on the planet millions of years ago. An asteroid may have collided with the surface of the earth and caused these species to die.

Humans can also contribute to the possibility of extinction for various species through things like overhunting, destroying habitats, or introducing nonnative species to areas where they are not usually found. In fact, have you ever heard of the dodo bird? When animals like pigs and cats were introduced to the dodo bird's environment, the bird became prey to the pigs and cats. As a result, they eventually became extinct because they could not adapt quickly enough to survive.

We hope you and your student(s) enjoyed learning about how animals and plants become extinct! If you want to learn even more, head over to our website and download one of our many free lesson plans about extinction, full of activities, worksheets, and more!

#ExtinctionForKids
#Extinction

What is the difference between "extinct" and "endangered"? Animals and other living things that no longer exist are extinct, and those that are in danger of becoming extinct are endangered. In this video, you and your kids will learn about some of the things that cause living organisms to die out. You will also learn how to help protect endangered species!

You probably already know about dinosaurs and that there are no more on the earth today. That is because they are extinct. They're not the only ones, though. Animals like woolly mammoths and dodo birds used to exist. However, due to certain natural causes and to human interaction, they no longer do. There are several reasons a species might die out. For the dinosaurs, scientists believe an asteroid collided with earth and caused a mass extinction.

On the other hand, woolly mammoths lost their habitats, and the climate changed drastically enough that they couldn't adapt to their new surroundings. Similarly, the dodo bird became extinct because of overhunting and the destruction of its habitat. Not all animals that go extinct existed thousands or millions of years ago. The passenger pigeon died out much more recently, and for the same reasons as the dodo.

What about endangered animals? For the most part, human causes are the reason most animals and other species are in danger of dying out. Animals you may be familiar with that are on the endangered species list include black rhinos, orangutans, Bengal tigers, blue whales, and sea lions. The video explains several causes, many of which are the same as those you already learned about.

While you can't do anything about extinct species, there are a few ways to help protect endangered animals and plants. You can recycle, save energy, and plant a garden. These will all help improve the environment. In addition, you can even sponsor an endangered animal!

We hope you and your student(s) enjoyed learning about animals that are extinct or endangered! If you want to learn even more, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

We all know the ocean is huge. But what else do we know? Ocean Facts for Kids offers just a few more interesting facts that you and your kids might not already know. For instance, almost 98% of all the water on the earth is in the ocean. The average depth is 2.3 miles deep. And that's just the average! One of the deepest parts is at the Mariana Trench, which is 36,198 feet deep—almost seven miles!

Do you know why there are waves? The most common type of wave is a surface wave. These are the ones we commonly see with the white tips that crash into the shore. These waves are caused by wind blowing across the surface of the ocean. Other waves occur because of gravity. These waves are called tides, which are affected by the moon's location in relation to the earth. And waves can even happen because of underwater explosions from volcanoes beneath the surface of the ocean. These explosions cause tsunamis!

Large parts of the ocean remain a mystery. Marine biologists estimate that there are between 700,000 and 1 million species that live in this ginormous pool. They also think that two-thirds of those species haven't even been discovered yet! That estimate doesn't include the millions of microorganisms living in the ocean.

We hope you and your student(s) enjoyed learning about the world's beautiful ocean! If you want to learn even more, head over to our website and download one of our many lesson plans about the ocean, full of activities, worksheets, and more!
