Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

There are a lot of interesting facts about you that people don't know. The same is true of every single person in history, including our presidents! In celebration of Presidents' Day, we are going to share a few interesting facts that you may not know about some of our past presidents. For instance, did you know President Lincoln was 6' 4" tall, making him the tallest president we've had? James Madison, on the other hand, was the shortest president, at only 5' 4" tall. All the other presidents' heights fell somewhere between those two.

We hope you and your student(s) enjoyed learning about past presidents! If you want even more information, head over to our website and download one of our many lesson plans, full of activities, worksheets, and more!

In this video your students and kids will learn how animals are classified into different groups. Classification breaks very large groups down into smaller groups. This makes them easier to be studied. Scientists classify animals, plants and insects based on things they have in common. Just like kids would do with their toys!

Taxonomy means to classify living things. Scientists and biologists use a taxonomy chart to classify all the organisms on Earth. This chart includes the following groups: Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species. Throughout the video we will learn about the different taxonomies, how animals are classified and spend a little more time on vertebrates and invertebrates. By the end you kid will have a more solid understanding of what makes animals different and may be able to classify them into their proper taxonomies.

Here’s a quick video where we learn to how to use the conditional with -ER verbs in Spanish.

And this is the same formula for many -AR and -IR verbs. Of course there will be some irregulars in a future video.

The conditional is a tense or mood used to say something would happen or someone would do something.
Please like the video and share with others who could benefit. More Spanish lessons coming.

Pilgrims for Kids will give you a brief history of the Pilgrims and the first Thanksgiving.

It all happened about 400 years ago. There was a group of travelers who came to America in search of religious freedom. They wanted to worship God in their own way in England, but they were not permitted. Instead, they boarded ships and went on a journey. These people are referred to as the Pilgrims.

The Pilgrims left Europe for America on September 20, 1620, and
established a colony called Plymouth. A colony is an area set up by a group of people who have usually traveled from the same country. It is a place where they settle to live, work, and raise their families.

Although the Pilgrims were happy to have settled in America, they faced a difficult and cold winter. They were not prepared. They built a large house and some smaller homes, but for a period of time people still slept on the Mayflower. Many of the Pilgrims died during the winter and of the 102 people who came across the Atlantic Ocean only 47 were still alive.

There were Native Americans living in the same area as the Pilgrims. Native Americans are the people who were already living on the land before the Pilgrims arrived in what is now known as America. They established a peace treaty with the Pilgrims. The Native Americans also agreed to trade for animal furs.

Some of the Native Americans also chose to stay with the Pilgrims and taught them how to plant corn, hunt, fish, and how to survive the cold winter.

After the first harvest in 1621, the Pilgrims invited some of the Native Americans to join them for a feast. Sometimes this is referred to as the first Thanksgiving as the tradition continued after every harvest in the years that followed.
