Adding using measurement problem


By Math mamoth

This lesson presents a measurement word problem that involves addition. A visual is used to write an equation and solve.

[4.NF.2-1.0] Compare Dissimilar Fractions - Common Core Standard


By Freckle by Renaissance

Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols greater than , = , or less than , and justify the conclusions, e.g., by using a visual fraction model. Front Row is a free, adaptive, Common Core aligned math program for teachers and students in kindergarten through eighth grade. Front Row allows students to practice math at their own pace - learning advanced concepts when they're ready and receiving remediation when they struggle. Front Row provides teachers with access to a detailed data dashboard and weekly email reports that show which standards are causing students difficulty, what small groups can be formed for interventions, and how their students are progressing in math.

Significant Digits & Measurements


By GetChemistryHelp

Significant digits (significant figures, sig figs) indicate the precision of a measurement. This lesson explains how to determine the number of significant digits in a measurement. For practice problems and additional chemistry lessons, visit http://www.getchemistryhelp.com.

Non-right triangle proofs


By Khan Academy

Sal gives a simple proof of the Law of cosines.

Similar triangles 2


By Khan Academy

Sal reviews all the different ways we can determine that two triangles are similar. This is similar to the congruence criteria, only for similarity!

Solving similar triangles 2


By Khan Academy

Sal solves two problems where a missing side length is found by proving that triangles are similar and using this to find the measure.

Similar triangles 2


By Khan Academy

Multiple examples where Sal analyzes the similarity of triangles.

Trigonometric functions and side ratios in right triangles


By Khan Academy

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.

Congruent Triangles and SSS


By Khan Academy

What it means for triangles to be congruent. All Khan Academy content is available for free at www.khanacademy.org

Non-right triangle proofs


By Khan Academy

Sal gives a simple proof of the Law of sines.

Trigonometric functions and side ratios in right triangles


By Khan Academy

Sal is given a diagram with multiple right triangles and is asked to match different expressions with different trig values.

Calculating the Radian Measure of an Angle


By AlRichards314

This video shows us how the radian measure of an angle is calculated. Remember that this does not change the angle, it is just another way for us to write its measure (somewhat in the same way that we can write a temperature in Celsius or Fahrenheit). This video shows us the measure of 1 radian, which will always be the same: 180 degrees/ pi, or about 57 degrees.

Inverse Right Triangle Trigonometry


By kthomp271828

Inverse trig functions are used to find missing angles rather than missing sides. This video explains how to use inverse trig to find a missing angle.
