Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

Cómo decir la hora en español:
En esta clase de español aprenderemos a pedir y dar la hora, además de algunos trucos para que sepas dar la hora como un nativo.
Las partes del reloj: https://youtu.be/JFjW5pl0qRA?t=22
La aguja pequeña marca las horas.
La aguja grande marca los minutos.
En algunos relojes también hay una aguja más fina que va más rápido y marca los segundos.
¿Qué hora es?
Son las ocho en punto: https://youtu.be/JFjW5pl0qRA?t=88
Se dice "en punto" cuando la hora acaba de comenzar y estamos en el minuto 00 de la misma. Es decir, la aguja de los minutos se encuentra en el número 12
¿Cómo sabemos que son las 8 en punto? https://youtu.be/JFjW5pl0qRA?t=126
Son las once y cuarto: https://youtu.be/JFjW5pl0qRA?t=193
Se dice "y cuarto" cuando la hora ha empezado hace un cuarto de hora. Si la hora tiene 60 minutos, son cuatro veces 15 minutos, por lo que si han pasado 15 minutos desde que empezó la hora, ha pasado un cuarto de hora.
¿Cómo sabemos que son las 11 y cuarto? https://youtu.be/JFjW5pl0qRA?t=233
Son las dos y media: https://youtu.be/JFjW5pl0qRA?t=310
Se dice "y media" cuando ya ha pasado media hora, es decir que la aguja grande se encuentra en el 6, la mitad de la vuelta completa.
¿Cómo sabemos que son las 2 y media? https://youtu.be/JFjW5pl0qRA?t=333
Son las once menos cuarto (de la noche): https://youtu.be/JFjW5pl0qRA?t=387
Como hemos visto antes, si faltan 15 minutos para que sean las 11, también se podría decir que falta un cuarto de hora para las once, por lo tanto: son las once menos cuarto.
¿Cómo sabemos que son las 11 menos cuarto? https://youtu.be/JFjW5pl0qRA?t=434
Más ejemplos de cómo dar las horas:
Las tres y cinco: https://youtu.be/JFjW5pl0qRA?t=498
Las cuatro y diez: https://youtu.be/JFjW5pl0qRA?t=507
Las diez y cuarto (también es correcto decir que son las diez y quince): https://youtu.be/JFjW5pl0qRA?t=517
Las ocho y veinte: https://youtu.be/JFjW5pl0qRA?t=535
Las siete y veinticinco: https://youtu.be/JFjW5pl0qRA?t=545
Las once y media: https://youtu.be/JFjW5pl0qRA?t=555
Las doce y treinta y cinco: https://youtu.be/JFjW5pl0qRA?t=572
La una y cuarenta: https://youtu.be/JFjW5pl0qRA?t=587
Las dos menos cuarto: https://youtu.be/JFjW5pl0qRA?t=597
Las cuatro y cincuenta: https://youtu.be/JFjW5pl0qRA?t=617
Las seis y cincuenta y cinco: https://youtu.be/JFjW5pl0qRA?t=627
Las cinco en punto: https://youtu.be/JFjW5pl0qRA?t=637

Academic vocabulary is a key part of the CCRS English Language Arts shift of complexity. But beyond the CCRS, academic language in general and academic vocabulary specifically have broad implications for our students’ lives. Academic vocabulary isn’t just for higher education; it’s another tool for our students to learn and use in order to understand texts; oral & written directions; communicate precise ideas when speaking or writing; comprehend language of assessments in the classroom and the workplace; describe thinking and problem-solving; participate more fully in social, community, academic, and work-related settings; and develop greater fluency in English. Join me to explore what academic vocabulary is, where to find tools to identify it and how to decide which words to teach and how to teach them, whether through conversation–at lower levels–or more explicitly at intermediate and higher levels. Leave with concrete ideas for teaching and tools that will save you time!

Parents and schools locked in pitched conflicts—over curriculum, book bans, policies that support LGBTQ students and staff—has been a dominant storyline for two years.
But the reality of school-family dynamics in many districts is not one of constant combat over highly politicized issues. That said, districts and schools often really struggle with fostering meaningful engagment with the families of the students they serve.
There are several ways that school districts can build effective relationships with parents and families. Inviting families to participate in the creation of district policies before a decision is made or providing spaces for parents to build community with each other are a few of the more intensive strategies that districts can implement. Joanna Geller, director of policy, research and evaluation at NYU’s Metropolitan Center, explains that there are also lighter touch techniques that districts can employ, such as providing translation services or simply inviting parents to board meetings can go a long way towards building positive family engagement. Here, she talks about what motivates parents to engage with their districts, and how districts can best support that work.
