Women in the 19th Century: Crash Course US History #16

Women in the 19th Century: Crash Course US History #16 Teacherflix 7 Views • 2 years ago

In which John Green finally gets around to talking about some women's history. In the 19th Century, the United States was changing rapidly, as we noted in the recent Market Revolution and Reform Movements episodes. Things were also in a state of flux for women. The reform movements, which were in large part driven by women, gave these self-same women the idea that they could work on their own behalf, and radically improve the state of their own lives. So, while these women were working on prison reform, education reform, and abolition, they also started talking about equal rights, universal suffrage, temperance, and fair pay. Women like Susan B. Anthony, Carry Nation, Elizabeth Cady Stanton, the Grimkés, and Lucretia Mott strove tirelessly to improve the lot of American women, and it worked, eventually. John will teach you about the Christian Temperance Union, the Seneca Falls Convention, the Declaration of Sentiments, and a whole bunch of other stuff that made life better for women.

Few women were as vocal for women's rights during the 19th century as Susan B. Anthony: https://www.commonlit.org/text....s/the-life-s-work-of
Anthony worked for women's right to vote alongside great women like Sojourner Truth, who stressed the importance of intersectional feminism in her influential “Ain't I a Woman?” Speech: https://www.commonlit.org/texts/ain-t-i-a-woman

Growth, Cities, and Immigration: Crash Course US History #25

Growth, Cities, and Immigration: Crash Course US History #25 Teacherflix 7 Views • 2 years ago

In which John Green teaches you about the massive immigration to the United States during the late 19th and early 20th centuries. Immigrants flocked to the US from all over the world in this time period. Millions of Europeans moved to the US where they drove the growth of cities and manned the rapid industrialization that was taking place. In the western US many, many Chinese immigrants arrived to work on the railroad and in mines. As is often the case in the United States, the people who already lived in the US reacted kind of badly to this flood of immigrants. Some legislators tried to stem the flow of new arrivals, with mixed success. Grover Cleveland vetoed a general ban on immigration, but the leadership at the time did manage to get together to pass an anti-Chinese immigration law. Immigrants did win some important Supreme Court decisions upholding their rights, but in many ways, immigrants were treated as second-class citizens. At the same time, the country was rapidly urbanizing. Cities were growing rapidly and industrial technology was developing new wonders all the time. John will cover all this upheaval and change, and hearken back to a time when racial profiling did in fact boil down to analyzing the side of someone's face.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. As America industrialized further and manufacturing grew, a rush of new immigrants came to America seeking job opportunities: https://www.commonlit.org/text....s/the-rush-of-immigr
Immigrants often entered through New York's Ellis Island where the Statue of Liberty bore the iconic phrase "Give me your tired, your poor,": https://www.commonlit.org/texts/the-new-colossus

Addition and Subtraction | Jack Hartmann

Addition and Subtraction | Jack Hartmann Teacherflix 7 Views • 2 years ago

Addition and Subtraction by Jack Hartmann introduces the operations of addition and subtraction.
Addition is adding 2 or more number and getting a greater number or sum. Subtraction is taking away to get the difference. Jack Hartmann introduces simple addition and subtraction word problems to show each operation. There is a special rule at the end for adding and subtracting zero to a number in this Addition and Subtraction video by Jack Hartmann. Addition and subtraction word problems.

Addition and Subtraction Lyrics

When you add you put together
When you add you get the sum
It's taking 2 or more numbers and getting a greater one
Adding is called addition
When you subtract you take away
When you subtract you get the difference
It's taking one number from another and always getting less
Subtracting is called subtraction
Let's try an adding problem I think you can solve
If you have 3 pencils, 3
And you add 2 more pencils 2
How many pencils do you have all together?
3 + 2 = 5
Let's try another adding problem, I think you can get it
If you have 2 dogs 2
And you add 2 more dogs 2
How many dogs do you have all together
1,2,3,4
2 + 2= 4
Let's try a subtracting problem I think you can solve
If you have 4 balls 4
And you subtract 2 balls 2
How many balls do you have left?
1,2
4 - 2 = 2
Let's try another subtracting problem
Think, you can do it
If you have 6 apples 6
And you subtract 3 apples 3
How many apples do you have left?
1,2,3
6 - 3 = 3
Now listen to this cool rule about number 0
When you add or subtract 0 the number doesn't change
When you add or subtract 0 the number stays the same
When you add you put together
When you add you get the sum
It's taking 2 or more numbers and getting a greater one
Adding is called addition
When you subtract you take away
When you subtract you get the difference
It's taking one number from another and always getting less
Subtracting is called subtraction

Unsolved Mathematical Problems for K-12

Unsolved Mathematical Problems for K-12 Teacherflix 7 Views • 2 years ago

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
