Organic food is a huge trend: it promises a healthier and better life. But can Organic food really live up to the expectations or is it just baloney?

Abraham Lincoln is largely considered one of the greatest presidents this country has ever seen. In Abraham Lincoln for Kids, you will learn so many wonderful things about this great president. For instance, did you know he was such a good wrestler that he is honored at the National Wrestling Hall of Fame?

Lincoln was born in Kentucky in 1809 to parents who could neither read nor write. He was rarely able to go to school and learned things himself from books he borrowed from others. At a young age, his mother died. After his father remarried, they moved to Illinois. Abraham worked as a storekeeper, surveyor, and post master. By the age of 25, he was elected to the local government.

He then started studying law and began working as lawyer. His work as a lawyer earned him the nickname many of us recognize—Honest Abe. This is because of the trustworthy way in which he ran his practice. Lincoln served one term in the US House of Representatives but failed twice in a row to be elected to the Senate. Nevertheless, his opposition to slavery helped him win the presidential nomination two years after his second Senate loss.

Abe Lincoln became president the same year as the start of the Civil War. He is known for his famous Gettysburg Address and the Emancipation Proclamation, which freed all slaves. He even crafted the Thirteenth Amendment. The end of the war finally came on April 9, 1865. Sadly, less than a week later, John Wilkes Booth assassinated the president, who had just been reelected for a second term.

We hope you and your student(s) enjoyed learning about the 16th president of the United States! 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!

This precalculus video tutorial provides a basic introduction into the gaussian elimination - a process that involves elementary row operations with 3x3 matrices which allows you to solve a system of linear equations with 3 variables. You need to convert the system of equations into an augmented matrix and use matrix row operations to write it in row echelon form. Next, you can convert back into a system of linear equations and solve using back substitution.

En este nuevo video para aprender español, exploraremos una historia emocionante que te ayudará a aprender español mientras sigues la travesía de un hombre que descubre que su portátil ha sido robado en el tren.

A lo largo del diálogo entre el hombre, la ladrona y un oficial de policía, aprenderás vocabulario clave y estructuras gramaticales importantes para situaciones cotidianas en español.



Frases clave y estructuras gramaticales:

"¡Oh no, ¿dónde está mi portátil?!": Uso del pronombre interrogativo "dónde" para preguntar por la ubicación.

"¿Alguien ha visto quién ha cogido mi portátil?": Uso del pretérito perfecto compuesto para expresar una acción reciente.

"Necesito su ayuda": Uso del verbo necesitar en primera persona del singular con el pronombre posesivo "su" para expresar una solicitud de ayuda.

"¡Te tengo!": Uso del pronombre personal "te" con el verbo "tener" para indicar posesión.
"Vamos": Uso del imperativo para expresar una invitación o sugerencia.

"Puedo oírlo sonar por esa zona": Uso del verbo modal "poder" seguido de un infinitivo para expresar habilidad o capacidad.

"Me temo que es demasiado tarde para disculpas": Uso del verbo temer seguido de un infinitivo para expresar una suposición o conclusión.

"Estás bajo arresto por robo": Uso del presente indicativo para expresar una acción actual.

"Va contra el protocolo pero haré una excepción esta vez" significa que la acción que se está considerando realizar no sigue las normas o procedimientos habituales establecidos por una organización o autoridad. En este caso, el oficial de policía reconoce que acompañar al hombre a recuperar su portátil no es lo que generalmente se haría según las reglas o pautas de la policía, pero está dispuesto a hacer una excepción esta vez. Esto implica que el oficial está dispuesto a hacer algo fuera de lo común debido a circunstancias particulares o por consideración especial hacia la situación del hombre.

En este video exploramos diversas actividades cotidianas relacionadas con el hogar, desde tareas de limpieza hasta reparaciones básicas. A través de varias escenas, los personajes interactúan utilizando un vocabulario útil y frases comunes en español. Este guión es ideal para estudiantes de español que quieren aprender términos y expresiones prácticas relacionadas con el mantenimiento del hogar.


Vocabulario y Frases Importantes:
Fregar los platos: "¡Madre mía, cuántos platos por fregar!"
Sacar la basura: "Mientras sigues con los platos yo me encargo de sacar la basura."
Planchar: "Después tengo que planchar la ropa."
Hacer las camas: "¿Podrías ayudarme a hacer las camas?"
Pasar la aspiradora: "¿Podrías pasar la aspiradora en el salón? Hay migas por todas partes."
Hacer la colada: "¿Dónde está el detergente? No lo encuentro por ningún lado."
Reparar la lavadora: "Creo que tendremos que repararla. Llamaré al técnico si sigue así."
Colgar un cuadro: "¿Te gusta cómo queda el cuadro aquí?"
Clavar un clavo: "Puedo repararlo pero necesitaré clavar un nuevo clavo."

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!
