En esta nueva clase de español veremos las diferencias entre cuatro verbos muy comunes: Decir, Hablar, Contar y Conversar.

Estos verbos se utilizan para describir acciones relacionadas con la comunicación, pero cada uno tiene su propio matiz y contexto de uso.

Veremos la diferencia entre ellos con diálogos en situaciones cotidianas.

En esta clase, aprenderemos a:

00:03 Decir: Usamos "decir" cuando queremos expresar o comunicar algo con palabras específicas. Por ejemplo, "Le tengo que decir una cosa".

01:57 Hablar: Este verbo se refiere al acto de comunicarse verbalmente en general. Por ejemplo, "Me animé a hablar con él".

04:10 Contar: "Contar" se usa para narrar o relatar una historia o suceso. Por ejemplo, "Me puedes contar lo que pasó en la fiesta".

06:05 Conversar: Implica un intercambio de ideas o información de manera informal entre dos o más personas. Por ejemplo, "Ayer conversé con Julia sobre sus próximas vacaciones en España".

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

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.

NOTE: Around the 4:40 mark, we mention that President Ford expanded the celebration of Black history from one week to the full month 50 years after President Lincoln announced the Emancipation Proclamation. The correct number is 113 years later. We apologize for the error.

Every February, Americans use the month to reflect on and celebrate the achievements of African Americans in American history. That is what Black History Month is all about. In this video for kids, you will learn how this particular month-long celebration came to be. At one point, the country didn't even study any events related to African American history because it dealt with such a tragic period in our history. In 1915, an African American historian named Carter G. Woodson decided to change that. "You must give your own story to the world," he wrote.

Woodson recognized that the predominately white historical association from which he was banned had no interest in attributing advances in science, technology, and other fields to non-White people. And very few people studied Black history at this time. School textbooks didn't even contain information about it. To give proper recognition to the accomplishments of Black Americans, he started the Association for the Study of Negro Life and History and declared the second week in February as "Negro History Week."

Carter Woodson chose this week because it commemorated the birthdays of two significant historical figures related to the freedom and equality of African Americans: Frederick Douglass and Abraham Lincoln. Frederick Douglass was an abolitionist who was born enslaved in the early 1800s. He was able to escape to the North and declared himself a free man, becoming an abolitionist and advocate for human rights. He met Abraham Lincoln on several occasions and may have influenced Lincoln's ideas on slavery.

It wasn't until Gerald Ford was president of the U.S. that the week-long celebration of Black history became a month-long period instead. Black History Month matters because it celebrates the sacrifices that so many Black Americans faced and endured to bring the country to where it is. As former President Obama stated, "We recommit to reaching for a day when no person is judged by anything but the content of their character."

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