Child prodigy Adora Svitak says the world needs "childish" thinking: bold ideas, wild creativity and especially optimism. Kids' big dreams deserve high expectations, she says, starting with grownups' willingness to learn from children as...

In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are...

In this video Paul Andersen explains how a sine or cosine wave can describe the position of the wave based on wavelength or wave period. A wave function can the position of a wave as a function or the amplitude and wavelength or the...

In this shorts video we will identify the equation of a perpendicular line. We are given a linear equation written in slope-intercept form. We are also given four answer choices in slope-intercept form. Each of the answer choices has...

In this math video we will find unit rate using a table. We will be given a relationship where one quantity is a fraction. We will set up and use a table to find the unit rate. We will find the reciprocal and multiply the fractional...

In this math video we will write and simplify a complex fraction to find unit rate. We are given a relationship and asked to find the unit rate. We will write the relationship as a ratio in fraction form. Since one of the quantities...

In this math video we will find unit rate using a table. We will be given a relationship where both quantities are fractions. We will set up and use a table to find the unit rate. We will find the reciprocal and multiply the...

In this math video we will write and simplify a complex fraction to find unit rate. We are given a relationship and asked to find the unit rate. We will write the relationship as a ratio in fraction form. Since both of the quantities...

In this quick math short, we start with the formula for the area of an isosceles right triangle and show how to rearrange it to solve for s, the side length. Then, we identify which of four answer choices gives an equivalent...

In this video, we’ll model and explain how to divide a whole number by a fraction — using the problem:
<
