Why do exams always tell you to use a number 2 pencil? What happens if you don’t? Quick Questions explains!

New ReviewIn this Grade 7 math lesson, students will learn how to determine the distance between the center of a circle and a point drawn on the circle when the radius is given. We begin by reviewing the definition of a circle’s radius and...

New ReviewIn this Grade 7 math video, students will learn how to extend a number pattern using a given rule with repeated division to find the sixth term. This step-by-step video models how to apply the rule correctly and use long division to...

New ReviewIn this math video lesson, students learn how to determine the approximate location of irrational square roots on a number line through a clearly modeled exemplar problem. The lesson begins by labeling the number line with perfect...

New ReviewIn this math video lesson, students learn how to use substitution to solve a system of linear equations in a clear, step-by-step way. The problem presents a system along with four possible solutions, and students are asked to determine...

New ReviewIn this math video lesson, students analyze a graph with six plotted points and determine which point could be removed so the relation becomes a function. The exemplar solution models how to apply the vertical line test, showing that...

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 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...

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 math video, viewers will match equivalent expressions. We will learn how to expand and simplify linear expressions by combining like terms and using the distributive property. We’ll work through four linear expressions, each...

In this short video we will answer a standardized high school math test question where we identify an equivalent exponential expression by simplifying. We will begin by using the Power to a Power Rule to "distribute" an exponent outside...

In this short video we will answer a standardized math test question using similar triangles to find a unknown angle. We will begin by reviewing the definition of similar figures. We will identify the corresponding angles and use the...

In this shorts video we will answer a standardized math test question using similarity. We will begin by identifying key information given in the problem and by defining similar figures. We will use this definition to identify the...

In this short math video we will use function notation to translate a function. We will understand that translating a function down impacts the y-coordinate of EVERY point on the function. We will rewrite the function by subtracting 4...

In this shorts math video, we will answer a standardized math test question about the conditional probability of drawing a blue marble from a bag of marbles. We will review the information provided to understand the number of marbles in...

In this short video we will Solve for x to determine the correct solution. We will first distribute to clear parentheses. Since the equation has variables on both sides, we will collect variable terms to one side using inverse...

In this shorts video we will find an unknown side length. We are given a pair of triangles and told they are similar figures. Using the definition of similar figures, similar figures have corresponding sides that are proportional, we...

In this shorts video we will rotate a segment 180 degrees. Will will understand that a rotation of 180 degrees is two 90 degree turns. We will rotate about a point or vertex, so, this will be the center of rotation. We will graph the...

In this shorts video we will factor a quadratic to solve a problem. We will draw and label a picture to represent the problem. We will use a square to model perfect squares and support factoring a quadratic. This quadratic is a...

In this shorts video we will learn how to write the equation of a line. We will begin by discovering that all the given answer choices are in slope-intercept form; y=mx+b. We will then review the information about the line that is...

In this shorts video we will learn how to factor a trinomial to answer a standardized math test question. We will first examine our answer choices and understand that each has been factored using a value of 8. We will use the table...

In this shorts video we will determine which graph is a linear function. We will first determine which of the four graphs is linear by understanding linear means a straight line. We will then learn how to determine which graph is a...

In this shorts video we will learn how to estimate a square root using a number line. We will first rewrite each integer value on the number line with its equivalent perfect square. We will identify which two perfect squares the...

In this shorts video we will learn how to find the volume of a cone. We will begin by writing the formula. We will identify the missing variables or dimensions of the cone. Using the provided image we will identify the diameter and...
