👉 Learn how to reflect points and a figure over a line of symmetry. Sometimes the line of symmetry will be a random line or it can be represented by the x or y-axis. Either way when reflecting a point and or figure over the line of...

👉 Learn how to apply transformations of a figure and on a plane. We will do this by sliding the figure based on the transformation vector or directions of translations. When performing a translation we are sliding a given figure up,...

This tutorial teaches how to make an origami butterfly using a 20 by 20 centimeter paper. The step-by-step instructions are easy to follow, and the end result is a simple and elegant butterfly that can be used for decoration or...

In this video lesson we will review how to add, subtract, multiply and divide fractions. We will make connections between adding and subtracting fractions. When you add and subtract fractions, you find a common denominator and add or...

In this video, we will see probability and random variables. We will then generate random numbers and set the seed. We will also look at probability distribution and chain rule of conditional probability. This video has a small...

In this video, the concept of probability is explained using the example of flipping a coin. Theoretical and empirical probability are discussed and compared. The video emphasizes the importance of comparing theoretical and empirical...

Mercury Bottle Flip

In this video, the teacher explains how to determine if two events are independent using the independence formula. They provide examples and guide students through the process of calculating conditional probabilities to prove...

In this video lesson, students learn how to find the area of a right triangle by composing a rectangle. The teacher explains the concept of a right triangle being half of a rectangle and demonstrates how to find the area of a triangle by...

The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the...

👉 Learn how to solve two-step linear inequalities and graph their solution. When solving two step inequalities we will use inverse operations, reverse order of operations and the properties of equality to solve. We will then graph our...

This clip is from the chapter "Excel 2019 Beginner: Creating Workbooks" of the series "The Complete Excel Guide: Beginners to Advanced".This section aims to teach you how to create a...

👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also...

This video uses the example of flipping a coin to determine if it is fair or biased to demonstrate testing a hypothesis with simulation. By running multiple trials and analyzing the response variable, they demonstrate how to make an...

Why do mirrors appear to flip images horizontally but not vertically?

This video provides a lecture on how to calculate expected outcomes when the probability of an event is known or estimated. The presenter explains that we can estimate the expected number of times an event will occur within a certain...

Physics Girl riddle: what happens to your image if you bend a spoon from concave to convex?

This video lesson teaches how to use sample spaces to find compound probability. The teacher uses examples such as rolling two dice, flipping coins, and different modes of transportation to school to demonstrate how to create sample...

In this video we will learn how to make an origami Flower

This video will be the perfect way to introduce your class transformations. Students will learn that a flip is a reflection, a slide is a translation, and a turn is a rotation, while also reviewing the concepts of symmetry and dilations,...

This video provides a clear explanation of how to multiply and divide fractions using simple processes. The presenter demonstrates how to multiply fractions by multiplying the numerators and denominators, and how to simplify complex...
