Dividing Fractions With Only 3 Steps Teacherflix 2 Views • 7 months ago

#fractions #homeschoolmath #math #homeschool #dividingfractions

This video walks you through 4 examples of dividing fractions. The key to dividing fractions is to remember the acronym KFC, which means keep, flip and change.

You want to keep your first fraction the same, flip the second fraction to its reciprocal, and change the sign to multiply. The division problem now becomes a multiplication problem and you can multiply straight across.

Improved math is a channel created to provide additional instruction on essential math concepts. I’m passionate about math and I know first-hand how important math concepts are in the real world.

Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.

The library of math tutorials that I create can also be used as supplemental instructional material for homeschool math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.

I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.

Improved math is creating more videos every day to cover topics from 4th grade, 5th grade, 6th grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!

Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.

Subtracting Fractions With Like Denominators Teacherflix 2 Views • 7 months ago

#math #mathhelp #homeschoolmath #mathtips

This video shows you how to subtract fractions when they have the same denominator. Subtracting fractions with like denominators is easy. All you do is subtract the numerators, keep the denominators the same, and simplify if you can.

Here is the video on how to simplify fractions: https://youtu.be/E_81dn_OYOA

You Use Quantum Physics to Smell Teacherflix 2 Views • 7 months ago

Your nose uses quantum tunnelling to smell! This crazy conclusion comes from the latest interpretations of the evidence about how our smell receptors detect odour molecules. This video summarises the two models of smell: shape theory and vibration theory, and concludes that you need both to explain how we smell.

The main reference I used for this video was "Life on the Edge" by JohnJoe McFadden and Jim Al-Khalili. Which I highly recommend, it is very well written and contains some brilliant science explanations. The field of quantum biology is utterly fascinating. https://www.amazon.com/Life-Ed....ge-Coming-Quantum-Bi

To err is to human, and I human a lot. I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors!

1. I misspelled Planck's Constant and wrote Plank's constant. Silly me!

Thanks so much to my supporters on Patreon. I hope to make money from my videos one day, but I’m not there yet! If you enjoy my videos and would like to help me make more this is the best way and I appreciate it very much. https://www.patreon.com/domainofscience

Also, if you enjoyed this video, you will probably like my science books, available in all good books shops around the work and is printed in 16 languages. Links are below or just search for Professor Astro Cat. They are fun children's books aimed at the age range 7-12. But they are also a hit with adults who want good explanations of science.

And grab your posters here: https://store.dftba.com/collec....tions/domain-of-scie In this map of plants I summarise all of the different kinds of plants from algae all the way through bryophytes, ferns, gymnosperms, angiosperms, monocots, eudicots, rosids and asterids. I explain how they are related to each other due to their evolutionary history, and the features that make plants so successful, leaves, roots, a vascular system, spores, seeds, flowers and fruits.

Quantum Simulation Explained in 9 Slides Teacherflix 2 Views • 7 months ago

Quantum simulation is a really promising route to discover new technologies of the future by finding new materials with new physical properties. Check out the Qiskit YouTube channel here: https://www.youtube.com/qiskit and this is a good playlist to start with https://bit.ly/2KxqOIV

I’ve talked before about how quantum simulation is my favourite application of quantum computing, so I thought I’d make a video to explain why. And in this video, I run an actual quantum simulation on a real world quantum computer.

You can implement this specific simulation too with this video: https://youtu.be/Z-A6G0WVI9w

The Map of Quantum Physics Teacherflix 2 Views • 7 months ago

This is the Map of Quantum Physics and quantum mechanics covering everything you need to know about this field in one image. Check out this video's sponsor https://brilliant.org/dos
And grab this poster here: https://store.dftba.com/collec....tions/domain-of-scie

I’ve been fascinated with quantum physics and quantum mechanics for a very long time and I wanted to share the subject with you so I made this map of quantum physics to lay out the ideas within the subject, to set some bounds on it so you know its not endless and to introduce you to lots of concepts that if you are interested in them you can dig deeper. When you are approaching a subject like this that’s so complicated it can be quite challenging because you don’t know where to start and you don’t know how all the concepts relate to each other so hopefully this will put everything in context.

This playlist expands on this video with lots of other more specific videos that dive deeper: https://www.youtube.com/playli....st?list=PLOYRlicwLG3
