‘Marketing Against The Grain’ is a HubSpot Original Podcast // Brought to you by The HubSpot Podcast Network // Produced by Darren Clarke.

About the Show
Kipp Bodnar, HubSpot’s CMO and Kieran Flanagan Zapier’s CMO, lead you down the rabbit hole of marketing trends, growth tactics and innovation. On the way you’ll pick up undiscovered strategies to give you that slight edge for success. These are not your typical twitter thread regurgitated marketing tactics that everyone is doing. These are new methods, with unfiltered examination of successful fresh ideas.

On this lesson, you will learn how to find the volume of a rectangular prism using the volume of a rectangular prism formula. This lesson includes whole numbers and fractions.

For more MashUp Math content, visit http://www.mashupmath.com and join our free mailing list! :)

This lesson answers the questions: How do I find volume? How do I find volume of a rectangular prism? How do I derive the volume formula? What is volume? What is the definition of volume? What are fractional edges? How do I find length, width, and height? Why is volume expressed in cubic units?

If you tried to sum up the last 150 years or so in one image, a chart of exponential growth would be a good place to start. It shows that some things change faster over time. You could apply it to life expectancy. Or compound interest. Or any number of things. But especially population growth. Back in 1798, a guy named Thomas Malthus noticed that not everything grows this way. And this caused people to worry because they were sure it would lead to massive death and starvation and famine. But that didn’t happen, thanks to something called the Green Revolution and a guy named Norman Borlaug. As we face a future population of ten billion and a world impacted by climate change, how will we do a Green Revolution 2.0? #GatesPartner

This short film features ideas on how to help pupils from disadvantaged backgrounds.
St Paul's CE Primary School in Stoke-on-Trent is a surrounded by areas of high deprivation. The school hands out basic food and hygiene packages to families in need. Staff also wash clothes on site for pupils who don’t have access to a washing machine.
Head Teacher, Nicola Finney says: “Never be afraid to ask the question - is everything okay? I see our school as a family, as a community. And if somebody in that family needs some support then we're going to support that family member. We're not going to turn our back on them.”
Barriers to success aren’t just limited to a lack of food or clothing.
Sarah Boyle, who teaches English at Falinge Park High School in Rochdale says: “We have a lot of young people who come to our school who have minimal understanding of English perhaps even minimal understanding of what a school day looks like and how a school day normally runs.” She runs a school debating team to help give students more confidence with their language skills.

Z-scores are used to relate any normal distribution to the standard normal distribution (mean =0, standard deviation =1). Once you have a z-score, you have to use a z-score table in order to calculate probabilities or areas underneath the standard normal curve.

This video focuses on how to use a z-score table to answer simple questions about z-scores and the percent of the distribution contained below, above, or between given z-scores.

Normal distribution images made using Geogebra.

0:00 Introduction
0:08 Z-score and z-score table
0:55 Area below a z-score example
1:55 Area above a z-score example

This physics video tutorial provides a basic introduction into torque which is also known as moment of force. Torque is the product of force and lever arm also known as moment arm. The lever arm is the perpendicular distance between the axis of rotation and the line of action of the force. Torque is the rotational equivalent of force. Positive torque values produce counterclockwise rotation and negative torques produce clockwise rotation. This video contains plenty of examples and practice problems of torques as it relates to doors, seesaws, and shovels. It discusses how to calculate the mechanical advantage of simple machines like seesaws and shovels.

Tiananmen Square, in the heart of the Chinese capital Beijing, has been a place of enormous significance in modern Chinese history.
For seven weeks in the spring and early summer of 1989, it was the focus of unparalleled protests by students and workers against the political and economic system, leading to a brutal government crackdown and international condemnation of the communist regime.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

What is water pollution? Did you know there are different kinds of pollution? In this video, you and your kids will learn all about the ways that water is harmed and contaminated. You will also learn how we can help make water cleaner and safer for the wildlife that live there. Even though we, ourselves, need clean water for drinking and other uses, aquatic animals that live in oceans and lakes need clean water as well to survive.

Would you rather swim in a lake that is clear and blue or one that is filled with plastic bottles and bags, waste, and chemicals? Naturally, you would want to swim in a clean lake. Well, so do fish and other animals in the sea. Water pollution is caused by many different factors, but the primary one is humans. For many, many years, we have been throwing our "trash" in the ocean. Sometimes our trash is made up of actual garbage, such as plastic water bottles and grocery bags, soda can holders, and straws. Other times, it's made up of sewage and waste, chemicals, and oils.

What can you do to help the water pollution problem? First of all, you can share some of the facts you learn in this video with your friends and family. For instance, did you know that over one billion people do not have access to clean water? That is 13% of the world's population! You can also follow the three R's: reduce, reuse, and recycle. Reduce your water usage, reuse items whenever possible, and recycle any items that you can.

We hope you and your student(s) enjoyed learning about water pollution! If you want to learn more, head over to our website and download one of our many free lesson plans about water full of activities, worksheets, and more!
