A year ago, Ayat Husseini’s dreams of going away to college looked like they were evaporating. Her parents, an immigrant couple from Lebanon, had cultural objections and fears about her leaving her home in New York City. This fall, Education Week checked back on Ayat, now happily ensconced on a leafy green college campus in Pennsylvania.

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!
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.

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

Do you know the difference between herbivores, carnivores, and omnivores? Do you know which one you are? In this video for kids, you will learn all about the three diets that animals (and even a few plants!) follow. You will also learn what exactly these three words mean.
One of the main characteristics that distinguishes the type of diet an animal will follow is the teeth. Herbivores only eat plants. These animals tend to have dull or no canine teeth and big, flat side and back teeth. They use their molars to crush and grind the plants they consume. Examples include sheep, cows, giraffes, rats, and grasshoppers. You could consider herbivores vegetarians!
Carnivores, on the other hand, only eat meat. They have long and sharp canine teeth next to their front teeth. They also have sharp cheek teeth called carnassials that help them cut up meat in their mouths. Carnivorous animals include lions, spiders, sharks, wolves, dragonflies, and the Venus fly-trap (which is actually a plant).
Finally, that leaves us with omnivores, which eat both plants and animals. Humans are omnivores because we consume both types of food. Omnivores have a combination of flat teeth and sharp teeth because they eat both plants and animals. Apart from humans, other omnivores include lizards, turtles, apes, catfish, and bears.
We hope you and your student(s) enjoyed learning about the diets of different animals! If you want to learn even more, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!
