Shimon Schocken and Noam Nisan developed a curriculum for their students to build a computer, piece by piece. When they put the course online -- giving away the tools, simulators, chip specifications and other building blocks -- they...

In this video, we investigate how changing the linear dimensions of a three dimensional solid affects the volume and surface area. Specifically, how do we solve for missing values (like side length, volume and surface area) when we are...

In this video, we practice calculating how volume and surface area would change as we change the linear dimensions of 3d figures.

In this math video we will learn about the relationship between translations & congruency. We will review how to perform a translation by translating a line segment four units right and four units down in a coordinate plane. We will find...

In this math video we will identify & determine congruent transformations. I will introduce a three part constructed response question. We are presented with a coordinate plane with two parallelograms. Part A asks us to determine what...

The video “Identify Transformations” analyzes transformations to determine whether a rotation, reflection, or translation has occurred.

In this video, the teacher explains how to identify the correct statements about a transformation of a triangle on a coordinate plane. The teacher goes through each answer choice and explains why it is either correct or incorrect,...

In this video, the teacher explains the four types of transformations in math - translation, reflection, rotation, and dilation. They then use a given problem to demonstrate how to identify a transformation that would result in a similar...

In this lesson you will learn how to prove the Pythagorean Theorem by using similar triangles.

In this lesson, students will learn how architects create scale drawings using fractions and decimals. They will understand the concept of a scale factor and how it is used to enlarge or reduce dimensions.

How to write counterpoint from a chord scheme. If you are working with a progression of chords and want to learn how to write contrapuntally around that harmonic scheme then this is the video for you. If you are analysing contrapuntal...

In this lesson, students will learn how architects use scale factors to draw designs with correct dimensions. They will understand the concept of ratios and how to write them in different formats.

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

This video lesson introduces dilations. Dilations are a transformation that changes the size of a figure by enlarging it by a scale factor greater than one or by reducing it by a scale factor less than one. Real world examples are...

In this video lesson we will learn how to rotate figures in the coordinate plane about the origin. We will understand that all rotations result an image that is congruent to the original figure. The origin will be the center of...

In this lesson on rotations, students will learn how to identify rotations and rotate figures in the coordinate plane. They will understand the vocabulary of transformations and how to tell when a transformation is a rotation. The...

This video lesson is the second video in the playlist or unit of videos on transformations. The first video explained translations. This video explains reflections as the mathematical flip over the line of reflection. Real world...

In this video lesson, we will learn the definition of similar figures. Similar figures are figures that are the same shape but different sizes. Similar figures have corresponding sides that are proportional and corresponding angles...

This video lesson introduces dilations. Dilations are a transformation that changes the size of a figure by enlarging it by a scale factor greater than one or by reducing it by a scale factor less than one. Real world examples are...

In this video lesson, students will be introduced to translations and understand its affect on congruence. We will discover that all figures translated in the coordinate plane result an image that is congruent to the original figure. ...

This video lesson introduces translations as the first of four transformations in this playlist. Students will learn that a translation is a mathematical slide. Students will learn to identify a translation and the effect a...

In this video lesson we will learn how to reflect images in the coordinate plane over the x and y axis. We will first identify the line of reflection given in the instructions. We will then determine the distance the original point is...

In this video, students learn about reflecting a parallelogram and how it affects the shape. The teacher explains the concept using vocabulary terms such as congruent line segments, congruent angles, and parallel lines.

In this video, students learn about the properties of congruence and how to determine if two figures are congruent using reflections. The video explains the concept of reflections, including how size and shape stay the same while...
