This video will teach you the fundamentals of algebra. You will learn about variables, variable expressions, numerical expressions, simplifying and evaluating algebraic expressions.

In this video, the teacher explains how to prove the similarity of triangles algebraically using ratios of corresponding sides. The lesson begins by reviewing the concept of proportionality and then applies it to triangles. The teacher...

In this video, the teacher explains how parentheses are used to write algebraic expressions and ensure clarity in their meaning. The teacher demonstrates how to write the expression "three less than a number, times twenty" using...

New ReviewIn this Grade 7 math video lesson, students will learn how to solve two-step equations with parentheses by connecting real-world situations to algebraic models. We begin by interpreting contextual scenarios and representing the...

New ReviewIn this math video lesson we will learn how to factor linear expressions using the greatest common factor (GCF) and rewrite expressions using parentheses, aligned to 7.EE.A.1. Viewers will be able to find the GCF of a linear expression...

New ReviewIn this lesson, students will learn how to simplify and factor linear expressions that involve multiple operations. We begin with a clear procedural checklist: 1️⃣ Rewrite subtraction as addition if necessary 2️⃣ Distribute to remove...

In this video lesson we will review properties of exponents. This video is intended as a review of previously learned concepts in Grade 8 for Algebra 1 students beginning a unit on Exponential Functions and Sequences. We will...

In this video, the teacher explains how to determine the initial value of a linear function by interpreting numeric, algebraic, and graphic representations. Using examples of an ice cream cup and a pool being emptied, the teacher...

In this math video, we’ll explore how to determine if a table represents an exponential function using a real-world bacteria growth scenario.

We start with a culture that begins with 1,000 bacteria, and each hour, the...

This video is a lesson on the laws of indices in mathematics. The speaker begins by explaining the basic special indices, such as anything to the power of 1 is the value itself, and anything to the power of 0 is 1. Next, the speaker...

New ReviewIn this math video lesson, students learn how to write the equation of a line parallel to a given line when the original equation is written in slope-intercept form and a point on the parallel line is provided. An exemplar solution is...

New ReviewIn this math video lesson, students learn how to write a system of linear inequalities from a given graph by analyzing key features of each boundary line and the shaded solution region. The modeled example begins by identifying the...

New ReviewIn this math video lesson, we will be finding the x- and y-intercepts of a linear equation written in standard form. The lesson begins by clearly defining each intercept: the x-intercept is the point where the y-value is zero, and the...

New ReviewIn this short math video, students learn how to factor a quadratic by grouping using a clear, five-step process. The lesson begins by reviewing the standard form of a quadratic, and then models each step carefully so students can follow...

New ReviewIn this math video lesson, students learn how to write the equation of a line that passes through a given point and is perpendicular to a given line. The visually modeled solution begins with a review of perpendicular lines, emphasizing...
