More than zero.

Fewer than many.

Do I pass your test (noting you need a bit of ~ in there to dumb down the Americans into nominal)?

The United States is 1 of the very few nations that had rejected the Metric System and still stuck on the Imperial system like foot and inch.

I'm pretty sure nearly all the students have studied meter and kilogram in the public schools, but they haven't actually well learned. Metrication has succeeded in Canada.

I experienced the change from Imperial to Meters first hand.

Please don't tell me what I know.

The "Great" US of A thinks it's still important.

It's not any longer. They just haven't internalized this fact.

Yet.

President Trump promised "Make America Great Again", "America First". #1 most coronavirus cases, #1 most Covid death of the entire world.

Are those statistics correct or simply undercounted?

I sincerely don't understand what you're asking.

Clearly, your President is a profoundly stupid person. But I think that is self-evident, and thus not a question to be asked.

What was the question? I sincerely like to answer questions.

Simply 1 good way for a loser trying to say he's winning. Being stubborn like this won't save much lives from the pandemic in the long run. Only 305 South Koreans have died from coronavirus so far.

Common Core Math is actually a good educational program, it visually allows the students to the discover the depth of the math nature, be able to calculate in any bases without the decimal base in the future.

Why can't all the students just learn both the traditional and Common Core methods, so they can calculate in the best ways especially across the multiple math bases?

Why is dozenal "better" than decimal?

Is there a better base than dozenal? If so, why not change to that one?

Taking you at face value (trusting that you are sincere), it's a little complicated.

Some, for some reason, believe that a White Man was given special powers (even though he was born in the middle east about 2,000 years ago, so was almost certainly at least brown if not black).

Then, recently, some dark-skinned people were killed by light-skinned people.

Caused some consternation (rightly so).

TL;DR: It's a little complicated. We're working the issue.

It's only hard to the American 4th graders.
What in heck is this collection of red herrings? Zimba and Common Core, bla, bla, bla...
A video link which has nothing to do with Common Core... ...and doesn't work.
Screenshots which have nothing to do with Zimba or with Common Core. Nor with the youtube video!

And then it becomes clear - the only message that you are pushing is that dozenal base is the solution to everything? The whole first part of the posting is just a bait for people who don't pay attention? How will this dozenal malarkey help with fifths or sevenths fractions - your screenshots in dozenal will look exactly the same if you attempt operations with fifths.

The multiplication table of 2, 3, 4, 6 are all easy in dozenal like the 2 and 5 in decimal.

1/3 = 0.4, 2/3 = 0.8

All the dozenal powers are way easier than decimal.

3, 9, 23(2 dozen 3), 69(6 dozen 9), 183, 509, the 3 and 9 ending digits pattern, do that same thing will be harder in decimal.

This video link should work -
https://youtu.be/pZ3A6E1w1II

We often cut cakes into 2, 3, 4, 6, 8 pieces.

The fractions of 5 and 7 are more rarely used.

Trigonometry is a popular late high school or university course, Pentagonometry is not even a word. 3, 4, 6 together should have more importance than 5. 1/7 to 6/7 are hard in both decimal and dozenal.

I don't see Common Core math involving the 5th as much as the 3rd.
