Khan Academy Review
• HSN.VM.4.c Understand vector subtraction v – w as v + (–w), where –w is the additive inverse of w, with the same magnitude as w and pointing in the opposite direction. Represent vector subtraction graphically by connecting the tips in the appropriate order, and perform vector subtraction component-wise. • HSN.VM.1 (+) Recognize vector quantities as having both magnitude and direction.
30 reviews for Khan Academy, 4.0 stars: 'Excellent free place to learn. I especially like the detailed videos; they look professional. I would like it if they had a Q&A or email function that let me talk to the instructors on the videos in real time.' Khan Academy, a free website aimed at promoting self-paced instruction, houses academic videos that are often baked into guided, adaptive instruction. With a focus on math, the site also offers video tutorials on a variety of topics in science, economics, the arts, and computing, as well as prep for tests like the SAT.

Meanwhile, Computer Science lessons cover important topics like data encryption and information theory. The Hour of Code tutorials are especially convenient since they boil lessons down into easily digestible one-hour chunks, perfect for busy adults or impatient children.

There isn’t even a requirement to setup an account to look at all their courses. Just click and go. The videos a well-produced and concise; a requirement for anyone who wants to learn, but has a tight schedule to meet.
It has a large following and is still considered one of the top choices among online, self-study alternatives. The price: free.
I even allow my students to complete some mathematics lessons independently on Khan Academy's website. This give students the freedom to work as fast or slow as they'd like. I've observed that low level learners and special needs learners enjoy the site's resources the most. I've also witnessed my students completing Khan Academy time on weekends and on long breaks. I think the fact that my high.
For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn. • 7.RP.3 Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Reasoning With Equations And Inequalities • HSA.REI.10 Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line). • HSA.REI.11 Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.
