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!

Chemistry on Khan Academy: Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

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!

Did you know that plants require a lot of the same things you do to grow and survive? In How Plants Grow for Kids, you will learn about four of the main things plants need to grow. These "core four" elements are soil, sunlight, air, and water. What do each of these things do for plants? Let's find out!
Plants will find most of the nutrients they need in the soil. These nutrients include nitrogen, phosphorous, and potassium. Nitrogen is what causes the leaves of plants to be green. Phosphorous contributes to the overall health and strength of the plant and its root system. Potassium helps the plant fight off diseases. Soil also supports the plant and helps prevent it from falling over.
The next element is sunlight. The sun produces energy through the light that plants can use to make food. The leaves are the part of the plant that makes this process, photosynthesis, happen. Without this process, plants would not be able to survive. However, too much or too little sunlight can be harmful. Another important element is air. From the air, plants receive carbon dioxide, a component that, like sunlight, contributes to the process of photosynthesis. Carbon dioxide also allows plants to use the sun's energy to make its food and grow.
Finally, plants need water. Water is necessary for the plant to grow healthy and strong. The water a plant receives helps guide nutrients to the plant through its roots, stem, and leaves. It is possible for plants to receive too much water. Too much sunlight harms plants, and overwatering them can yield the same results. A couple other things plants need are temperature and space. Adequate temperatures ensure plants don't die out because of extreme hot or cold. And plants need enough room to grow into their full size. Overcrowding can cause disease or restrict plants from receiving enough air.
We hope you and your student(s) enjoyed learning about the factors that affect plants and their growth! If you want to learn even more, head over to our website and download one of our many free lesson plans about plants, full of activities, worksheets, and more!

Many students need to see math presented in a lot of different ways. Using a variety drawings and manipulatives can often help students understand complex and abstract math concepts. The CRA (Concrete-Representational-Abstract) model, as known as multiple representations, can be a powerful tool to help students who are struggling to understand what a math concept really means.
In this video, Sarah Powell from UT demonstrates three different ways to represent numbers and math concepts, providing a guide to using multiple representations in your own classroom.
This video is a part of the Best Practices series, meant to help build math teachers' teaching tool belts and provide the best research-based strategies to help students who struggle with math. This video is also part of Project STAIR, a research-backed resource for math teachers and parents whose students are struggling in math.
