In this lesson, students will learn how to divide whole numbers by unit fractions using a model. By visualizing the problem and representing the whole numbers as rectangular holes, students can easily understand the concept. They will...

In this lesson, students will learn how to find a common denominator for fractions with unlike denominators by creating number lines. By dividing each fraction's parts into equal divisions, they can determine a common denominator.

In this video, students are taught how to divide a whole number by a non-unit fraction by thinking about equal groups. The video explains the concept of division and provides examples and strategies for solving division problems...

This lesson helps students develop a solid foundation in understanding fractions and their relationship to whole numbers. By visually dividing the shapes into equal parts and shading the appropriate fractions, students will gain a clear...

Series | Limit Comparison Test: Example 2

In this video, students learn how to position a group of numbers that include decimals, fractions, and integers on a number line. They review how to order decimal numbers from least to greatest and how to change decimals to fractions and...

The Music Theory Crash Course continues with our look at cadences. This time we break down the Imperfect Authentic Cadence. We look at some cadence examples on the piano and explain how to identify an Imperfect Authentic Cadence as well...

This lesson begins with a review of equivalent fractions and the concept of common denominators. It then demonstrates how to deconstruct mixed numbers into fractional parts and multiply to form equivalent fractions. Finally, the video...

In this video, the teacher explains how to describe fractions of a rectangle by counting unit fractions. They use examples of rectangles partitioned into halves, thirds, and fourths to demonstrate how to count the unit fractions that are...

👉 Learn how to find the derivative of a function using the product rule. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the variable x. The process of finding the...

👉 Learn how to graph linear equations written in standard form. When given a linear equation in standard form, to graph the equation, we first rewrite the linear equation in slope intercept form, (i.e. in the form y = mx + c, where m is...

In this video, students learn how to write fractions by looking at sets of objects and grouping them into equal parts. The teacher explains that fractions represent equal parts of a whole, whether it's breaking shapes or sets of objects....

In this video, students learn how to identify improper fractions on a number line by dividing it into equal parts. The teacher uses the analogy of dividing a candy bar into thirds to explain the concept. Students also learn that the...

In this video, the teacher explains how to determine the unit rate by using the multiplicative inverse of a measurement. They provide examples and step-by-step instructions on how to find the unit rate using fewer steps than with a...

In this lesson, students will learn about the concept of opposites of fractions by using a number line. They will understand how the numerator and denominator determine the location of a fraction on the number line and how to identify...

In this video, the teacher explains how to multiply a fraction by a mixed number using visual representations. The lesson begins with a review of fractions and their parts, the numerator and denominator.

How well do you know your intervals? Interval recognition is a core skill in for any musician with questions like these often appear in music theory exams. In this music theory lesson you will have an opportunity to discover how accurate...

Music can often be quite symmetrical, which is great, because humans tend to love symmetry. Season 4, Episode 4

How good is your ability to work out the interval between two notes? In this music theory lesson we practice working out intervals. Do you know your Major intervals from your Minor intervals or your Augmented intervals from your...

Season 3, Episode 21 - Two Minute Music Theory The third installment in our Building Chords Series. Today we look at building all types of Seventh Chords, which are extensions of the basic triad.

How to graph a polar point using coterminal angles

As we continue our Chords series, today we look at the chords that can be made using the major and minor keys - which are called Diatonic Chords.

👉 Learn how to evaluate the limit of a function involving trigonometric expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time....

A surd is a square root which cannot be reduced to a whole number.



Surds are irrational; they are decimals that never end and never repeat, so cannot be written as fractions. Leaving a number in it's surd form is...
