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.

With a teacher-to-pupil ratio of 1:80 in most Nigerian schools, the quality of pupils’ attention and learning engagement continues to be on a nosedive trajectory with a negative impact on pupils’ motivation to learn, increasing drop-out rate, and the socio-economic risks of a poorly educated populace. According to a report by the United Nations Children's Fund, over 58.3% of pupils in Nigerian schools are not learning effectively (Vanguard News, 2018). Teachers are also becoming ineffective at inspiring pupils’ concentration via a classroom atmosphere that facilitates effective learning. The additional demands on teachers due to the higher pupil to teacher ratio also limits opportunities for teachers to offer personalised learning adapted to the children’s learning needs and providing the necessary psychological support.

This work explores how deep learning-powered cameras in a classroom can assist teachers to recognize and assess their pupils’ engagement levels and classroom behavioural patterns, with the goal of intervening when students need motivation and assistance. Specifically, the artificial intelligence algorithm assesses the students' facial expressions, classroom activities and their demonstrated levels of interest. We propose an integrated approach that includes neural network facial recognition and an Apriori-based mood extraction and human action detection to uniquely understand each pupil's learning needs. With a relatively low-cost camera that can quickly and precisely read pupils’ facial expression and class behaviour, many learning risk indicators such as emotional stress, personal frustrations, fatigue, academic disconnection and learning dysfunction can be automatically identified, allowing the teacher to intervene appropriately as needed.

We ground our instructional methods in the three R's: Rigor, Relevance and Relationships. Watch this video to learn more about how we apply these methods in our classrooms and how they seek to challenge students and promote a love of learning.

The process of completing the square for a quadratic expression, equation, or function can seem confusing at first.

What do you do when a=1?

What do you when a is not 1?

Well, with the method discussed it doesn't matter what value of a you are working with.

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.

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.

Is teaching teaching grammar to young children essential? Yes! It is vital to explain to young children how our language works. Learners will read and write better if they understand the fundamental building blocks of sentences. Nouns are an essential part of sentence structure because they form the subject in a sentence; without a subject, a sentence cannot be complete. After teaching nouns, your students should recognize that a noun is a name of a person, place, or thing. Also, they should be able to identify nouns in sentences. For this reason, teac hers should start by teaching nouns using simple words students can understand. Come along as we explain Nouns for Grade 1. To get our free noun worksheets, visit this linknotion

We look at the trigonometric functions: sine, cosine, and tangent used to work out sides and angles in right angle triangles.
You will learn the following steps -
1. Labelling the sides - opposite, adjacent and hypotenuse,
2. Determining which trig function should be used - SOHCAHTOA - (sin = opposite / hypotenuse,
cos = adjacent / hypotenuse, tan = opposite / hypotenuse)
3. Substitution of values.
4. Calculation.
By going though all the trigonomic functions this video will help you master this topic - through the use of a few math tricks! To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU

When we tell a story, we must follow the right order - and to indicate this order of events, we can use sequence words. In this instructional video, Owen talks about these sequence words and gives an example of how to structure a story correctly, using them.

This video is part of a broader lesson plan that is aligned with CCSS.ELA-Literacy.CCRA.W.3: "Write narratives to develop real or imagined experiences or events using effective technique, well-chosen details and well-structured event sequences."
