Your rich, eccentric uncle just passed away, and you and your 99 nasty relatives have been invited to the reading of his will. He wanted to leave all of his money to you, but he knew that if he did, your relatives would pester you...

New ReviewIn this math video lesson, students learn how to rationalize a denominator when a radical expression appears in the denominator of a fraction and rewrite the expression in simplest form. The modeled example begins by reinforcing the idea...

New ReviewIn this short math lesson, we’ll solve a quadratic equation step-by-step using completing the square. We follow 6 quick steps: 1️⃣ If necessary, “move” c to the right side of the equation. 2️⃣ If necessary, divide all terms by a. 3️⃣...

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 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 math video we will factor using difference of squares to answer a standardized math test question. We will begin by identifying the first and last term are both perfect squares. We will identify the pattern of difference...

In this shorts math video we will find the side of a square using area. We are given the area of a square and asked to find the side length of the square. We will review and use the formula A=s^2, (A equals s squared.) We will rewrite...

In this math shorts, we’ll estimate an irrational square root using a number line and perfect squares! Watch how we find which perfect squares a non-perfect square root falls between — and how to decide which it’s closest...

Is the square root of a number rational or irrational? In this 8th grade math lesson, we’ll break it down step by step!

👉 First, we’ll define rational and irrational numbers in simple te
rms.
👉 Next, we’ll explore square...

A video entitled "Square and Cube Roots" which relates square roots and building perfect squares with Legos.

A video entitled "Estimate Approximations" that covers the process of approximating square root terms without the use of a calculator.

Pupil outcome: I can represent a square number. Key learning points: - A square number of objects can be arranged into a square array. - A square number can be represented as the product of two factors which are the same. - When both...

Pupil outcome: I can identify the highest square factor of any term including those written with algebra. Key learning points: - Numbers can be classified as surds or not surds. - Square factors of numerical and algebraic terms can be...

Pupil outcome: I can simplify surds. Key learning points: - The radicand should be as small as possible. - If any of the radicand's factors are square numbers then the surd can be simplified. - Algebraic factors that are square values...

Pupil outcome: I can explain the concept of square root and cube root and calculate them. Key learning points: - The square root of any perfect square will be an integer. - The square root of any perfect square will be an integer and can...

Pupil outcome: I can calculate with roots and integer indices, including estimating the answer. Key learning points: - Integer indices state how often a number should be multiplied by itself. - The square root of any perfect square will...

Pupil outcome: I can generate coordinate pairs using the equation of a circle in the form x^2 + y^2 = r^2 and then draw the graph. Key learning points: - A table of values can be useful to identify coordinate pairs which satisfy the...

Pupil outcome: I can solve quadratic equations algebraically by completing the square. Key learning points: - There are other methods to find the solutions of a quadratic equation. - One of these methods is called completing the square....

Pupil outcome: I can identify the key features of a quadratic graph. Key learning points: - A quadratic graph is a parabola. - The roots of a quadratic graph are where the graph intersects with the x-axis. - The turning point is the...

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

In this video, we identify the center and radius of a circle by writing the equation in center-radius form. We do this by completing the square with the given equation. This video assumes you have a basic knowledge of how to complete the...
