In this math video we will determine the proof of the Pythagorean Theorem using squares. We will be present with an image created from three squares connected at their vertices to form a right triangle in the center. We will be presented...

In this math video we will solve a math problem using the converse of the Pythagorean Theorem. We will understand the if the longest side of a triangle squared is equal to the sum of each square of the remaining two sides, then the...

In this math video we will find distance in the coordinate plane. We will understand that we can create a right triangle using a coordinate plane. We will also understand that the Pythagorean Theorem applies to any right triangle and is...

In this math video we will be using the Pythagorean Theorem to solve a real world problem. We will understand that the Pythagorean Theorem applies to any right triangle. We will identify the legs and hypotenuse of a right triangle. We...

In this math video we will determine the possible lengths of the missing side of a right triangle. We will be given two side lengths and asked to determine two possible lengths for the third side. We will understand that the Pythagorean...

In this math video we will describe the two dimensional face formed from slicing a 3D figure. We will relate the number of faces passed through when slicing to the number of sides on the two dimensional cross section. We will visually...

In this math video we will determine how many unique triangles can be formed. We will be given three angle measures and asked how many unique triangles can be formed. We will review and understand that the three interior angles of any...

This video explains the concept of translation in mathematics using the analogy of an ice skater gliding across the ice. It demonstrates two methods for translating figures on a coordinate plane, emphasizing the importance of maintaining...

Mr. Addit provides information about measuring with the metric scale. He then measures length, perimeter, and area.

Mr. Addit explains how to calculate the perimeter of a square and a rectangle. He then gives examples of calculating the perimeters of three-sided, five-sided, and six-sided shapes.

This video explains interior and exterior angles of a polygon. In particular: how to calculate interior and exterior angle, how to find the sum of interior or exterior angles, and how to find the number of sides of a polygon with just an...

Pythagoras' Theorem Explanation: This video is an introduction lesson for Pythagoras' Theorem. Why is it useful to know Pythagoras' Theorem? What is a hypotenuse? Watch this video to find out. Practice questions and answers are at the...

Angle Rules: This video explains the basic angle rules which are extremely helpful to know when solving geometry problems. Rules covered are: angles in a triangle, angles in a quadrilateral, angles on a straight line, angles around a...

Mr. Addit explains the term reflection. He also reflects various plane shapes across the line of symmetry and examines the reflected images.

Mr. Addit explains the line of symmetry, and examines a variety of plane shapes to find lines of symmetry.

Mr. Addit describes the four main types of triangles and explains what makes each type unique. He models drawing the four different triangles.

Mr. Addit reviews points, lines, angles, and triangles and how to classify them.

Mr. Addit reviews two-dimensional plane shapes and introduces three-dimensional shapes and discusses their attributes.

Mr. Addit provides an introduction to polygons and quadrilaterals, and tells how polygons and quadrilaterals can be found in the environment.

Mr. Addit reviews two and three dimensional figures.

Mr. Addit reviews fractions and explains how fractions are similar to probability ratios.

John Singleton Copley portrait of Paul Revere illustrates the ethical nature of creating luxury goods in pre-revolution America and how it lead to revolt.

“Shapes + Shapes = Bigger Shapes” demonstrates how to construct shapes and pictures from component shapes included in pattern block sets.

This is a brief introduction of using visual models to represent fractions. Four different visual models are presented.
