In this video, students learn how to identify equal numbers of ones, tens, and hundreds using number models. The teacher explains the base 10 system and demonstrates how to count the number of hundreds, tens, and ones represented in...

This video continues introducing the basic building blocks for the successful study of geometry. This video goes over 7 examples involving the union and intersection of geometric figures.

In this video, the teacher explains the concept of geometric sequences and how to find the explicit rule for such sequences. They also demonstrate how to find specific terms in a geometric sequence using the explicit rule.

This video is a lecture on electric fields, focusing on the definition and characteristics of electric fields, how they are represented on diagrams using electric field lines, and how they can be used to explain phenomena such as static...

This video is a lecture on co-linear resultant forces, where the effects of multiple forces acting on objects along the same line are discussed. The lecture covers examples of forces acting in opposite and same directions, and how to...

This video is about the role of digestive enzymes in the chemical breakdown of large, insoluble molecules in our food into smaller, soluble ones. The video focuses on the three main types of digestive enzymes - carbohydrase, protease,...

Functions can be thought of as mathematical machines, which when given an element from a set of permissible inputs, always produce the same element from a set of possible outputs

Epidemic curves are an important component of the public health and global health toolbox. During an outbreak of an infectious disease, public health professionals and epidemiologists create visual representations of the onset of illness...

In this video, students will learn about the relationships between digits and their place value using base 10 blocks and a place value chart. They will understand how the value of a digit changes as it moves up on the place value chart,...

The video is a lecture on circular motion, explaining why objects move in circular paths and the forces that cause this motion. The examples used in the video include the moon orbiting around the earth, a car on a roundabout, and an...

Understand the relation between place values as multiplication by 10.

👉 Learn about solving rational equations. A rational expression is an expression in the form of a fraction where the numerator and/or the denominator are/is an algebraic expression. There are many ways to solve rational equations, one of...

👉 Learn how to solve proportional rate problems using integration. The integral, also called antiderivative, of a function is the reverse process of differentiation. Integral of a function can be evaluated as indefinite integral or as a...

This video is about gravitational potential energy, focusing on what it is and how it is calculated. The video also provides an equation for calculating changes in gravitational potential energy and provides examples of how to use it....

In this video, we demonstrate the process of lining up decimals and comparing digits to determine which number is greater. We discuss the concept of irrational numbers continuing on forever without repeating and the use of symbols to...

In this video, the teacher explains how to divide two polynomials using polynomial long division. The process is similar to dividing numbers, where the dividend is divided by the divisor to obtain a quotient and remainder.

In this lesson, students learn how to compose real-world problems by interpreting numerical expressions. They review the order of operations and then create situations that can be represented by given expressions.

Represent mixed numbers and improper fractions using visual models.

This video continues introducing the basic building blocks for the successful study of geometry. This video goes over 3 slightly more challenging examples covering the appropriate way to denote and name angles formed by points on a...

The Fibonacci sequence is a series of numbers in which a given number is the addition of the two numbers before it. So, if you start with 0, the next number will be 1, followed by 1, followed by 2, followed by 3 and so on. As you can...

In this video, the teacher explains the difference between scatter plots and lines. They discuss how scatter plots represent inexact relationships between variables, while lines represent exact or deterministic relationships. The teacher...

In this lecture, the speaker explains how to use the logarithmic graph to estimate parameters in the form of KB to the power of X. The speaker shows how to take the logarithm of both sides of the equation to bring X down out of the way,...

In order to mathematically describe a line in 3-dimensional space, we need a way to define the values of the three coordinates at every point along the line. This can be done by creating a group of "parametric equations".

This nugget describes the nucleus of an atom. It talks about the various aspects of a nucleus like atomic number, atomic mass unit, isotopes and isobars, with examples.
