In this video, I show you how easy it is to multiply fractions! Multiplying fractions is one of the easiest things to do because you simply multiply straight across.

In this video we cover:
Review of the steps to adding and subtracting fractions
Step by step process for multiplying fractions
The first step is to multiply numerators together, then multiply denominators together. Finally, you simplify if needed.

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 and during the pandemic. 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.


Thanks for watching my channel.

In which John Green teaches you about Nationalism. Nationalism was everywhere in the 19th century, as people all over the world carved new nation-states out of old empires. Nationalist leaders changed the way people thought of themselves and the places they lived by reinventing education, military service, and the relationship between government and governed. In Japan, the traditional feudal society underwent a long transformation over the course of about 300 years to become a modern nation-state. John follows the course of Japanese history from the emergence of the Tokugawa Shogunate to the Meiji Restoration and covers Nationalism in many other countries along the way. All this, plus a special guest appearance, plus the return of an old friend on an extra-special episode of Crash Course.

How Many Faces, Edges And Vertices Does A Triangular Pyramid Have?
Here we’ll look at how to work out the faces, edges and vertices of a triangular pyramid.
We’ll start by counting the faces, these are the flat surfaces that make the 3D shape. A triangular pyramid has 4 faces altogether - all triangles.
Next we’ll work out how many edges the tetrahedron has, which are where two faces meet. A triangular pyramid has 6 edges.
Next we’ll count the corners of the tetrahedron (the corners). 4 altogether.

Here's a LOOP version of one of my most popular videos. It is a song I learned in High School Spanish to help with irregular verbs in the preterite.

Explanation video here:
https://www.youtube.com/watch?v=MXsivRHsvas&t=11s&ab_channel=SenorJordan

I have changed the line "no acentos" to "no hay acentos" as it still fits ok and is better grammar in Spanish.

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

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.

The above are candidate problems. Teachers and mathematicians are gathering in November 2013 to select the final set of thirteen unsolved problems. The results are here:
http://www.youtube.com/watch?v=wV5-wMGRM3g&feature=share&list=PLSrbLTVLJpchKVD0uUOEa2S-eSK9a3Kxp

When: November 15-17 2013
Where: Banff International Research Station

The conference will also discuss whether the $1,000,000 rewards are a good or bad idea. People have strong opinions on the topic. Some see no other practical way of getting these beautiful problems the exposure they need to inspire students worldwide. However, there are problems:

1) The joy of learning for its own sake may be compromised if the ulterior motive of a cash reward gets into the classroom.

2) The Clay Mathematics Institute released the seven $1,000,000 Millenium problems in 2000. Their purpose is to inspire mathematicians and the problems are tough to understand for non-mathematicians. Here is the problem... Nick Woodhouse says that the Clay Mathematics Institute gets about six wrong solutions every day! We need a different mechanism for dealing with "solutions" so we are not inundated.

3) The system that is set up must also try to minimize legal challenges. Again, the Clay Mathematics Institute has had its fair share of bad experiences here.

______________________________________


For those coming to the November 2013 conference... If you are able, think of some unsolved problems that may be understood by a typical classroom of students. The educators at the conference will help place these into the curriculum and develop them so every child experiences both moments of success and moments of struggle. We need to deliver a sense of accomplishment for all children as they come to understand and work on the unsolved problem.

For example, one potential grade 4 problem is the Collatz (3N+1) conjecture. This unsolved conjecture can be paired with the (3N-1) conjecture which is consistently solved by all grade 4 classrooms: http://youtu.be/R4oINmqHXVY

Here are other potential unsolved problems:

Kindergarten: Packing Squares (Erdős and Graham, 1975)
Grade 1: No-Thee-in-a-Line (Henry Dudeney, 1917)
Grade 2: Sum-Free Partitions (Issai Schur, 1916)
Grade 3: Graceful Tree Conjecture (Ringel, Kotzig & Rosa, 1967)
Grade 4: Collatz Conjecture (Lothar Collatz, 1937)
Grade 5: Play Perudo Perfectly (Atahualpa & Pizarro, 1530s)
Grade 6: RSA Cipher (Rivest, Shamir & Aldeman, 1978)
Grade 7: Egyptian Fraction problem ???
Grade 8: Problem using the Pythagorean Theorem ???
Grade 9: Exponents problem or Three-Body-Problem (D'Alembert & Clairaut, 1747) ???
Grade 10: Inscribed Square Jordan Curve (Otto Toeplitz 1911)
Grade 11: Solutions to x^2 + y^2 + z^2 = 3xyz (Markoff, 1879) ???
Grade 12: ??? (The Sudoku problem on the video above has been solved.)

Here is a tentative list of criteria that you might consider in thinking about suitable unsolved problems: http://www.mathpickle.com/K-12/Criteria.html
