6.RP.1 / 6.RP.3 - Model Ratios Using Tape Diagrams
By MathwithMrAlmeida
In this video, Mr. Almeida explains how to model ratios using tape diagrams or bar models. This meets Common Core standard for mathematics of 6.RP.1 and 6.RP.3 (stem only).
6.RP.3 - Solve Word Problems Using Tape Diagrams
By MathwithMrAlmeida
In this video, Mr. Almeida shows you how to solve ratio word problems using tape diagrams. The models create equivalent ratios because you are multiplying both quantities in one ratio by the same positive number (the length of 1 unit). This meets Common Core Standard for Mathematics 6.RP.3.
How to use Ratios and Proportions to Solve Real World Problems
By mrtedmartin
Instructor uses a Power Point presentation to demonstrate how to use ratios and proportions to solve problems real world problems. Unit rates are discussed and definitions are given. Solving unit rate problems are modeled and a calculator is used for computation.
Trigonometric Ratios of Special Angles
By AlRichards314
This video shows us how we determine the trigonometric ratios for the angles of 30 degrees, 45 degrees, and 60 degrees. Keep in mind that the ratios of the sides corresponding to these angles never change (even though the side lengths may change). That means that knowing the values for these trig ratios means you'll know them forever! They won't change!
Trigonometric functions and side ratios in right triangles

Sal is given a diagram with multiple right triangles and is asked to verify identities relating to trig ratios in those triangles.
Trigonometric functions and side ratios in right triangles
By Khan Academy
Sal explains how the trigonometric ratios are derived from triangle similarity considerations.
Division of Rational Expressions
By MrLovellFord
Shows how to divide two rational expressions by mulitplying the first expression by the reciprocal of the second, then simplifying.
[4.NF.1-1.0] Generate Equivalent Fractions - Common Core Standard
By Freckle education
Explain why a fraction a/b is equivalent to a fraction (n x a) / (n x b) by using visual fraction models
