At the turn from the Middle Ages to Modern History, the Army of the Ottoman Empire was the most dominant military force in the World.
Entire Empires and Kingdoms disappeared on their marching route.
From the Middle East to Central Europe, no one could match the bravery and excellence of the Ottoman soldiers.
The best and most reputable among them were Janissaries.

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

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.

Los artículos acompañan a los sustantivos y concuerdan con el género del mismo.


Si el sustantivo es masculino, usará un artículo masculino y si es femenino, usará uno de ese género. También tenemos los artículos plurales para cuando son una cantidad mayor a uno.

Algunos sustantivos no son ni femeninos ni masculinos, para lo que se usaría entonces el artículo neutro.

En este nuevo video para aprender los artículos en español veremos montones de ejemplos del uso de los artículos, con ejercicios para que puedas practicar en casa.

También incluye diálogos con vocabulario para que puedas practicar español.

Hoy aprenderemos la voz pasiva

La voz pasiva se utiliza cuando se quiere poner el foco de atención sobre la persona o cosa que es objeto de una acción.

Mientras que en la voz activa, la que se una normalmente, el foco de atención está en la persona o cosa que realiza dicha acción.

Es decir, una oración pasiva es aquella en la que el sujeto recibe la acción del verbo y el complemento agente la realiza.

Con nuestro vídeo para aprender la voz pasiva podrás aprender la diferencia entre ambas fácilmente ya que te mostraremos con ejemplos como se utiliza cada una.

También veremos algunos ejemplos del uso de oraciones pasivas con el verbo en activa.

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!
