In 1st grade, fractions made perfect sense to me, so I reduced them like this in my head. The school boosted me to a 2nd/3rd split class to keep me engaged. So my parents immediately left the state so the school wouldn't look into our home situation. Not really relevant to this post, but every time I see fractions, I still get mad about that.
Schools are buiness, thier funding depends on a specific pass fail rate. They teach you a convoluted way to do something, to encourage a percant of failure. If a teacher strays from that curriculum they can be fired. Learning fractions are the same as divsion made a differance. The only class I ever failed was business cal. The teacher was hard to understand and would be voilently upset if you asked a question. The next business calc teacher taught calc III, aced his class, he knew the shortcuts
Small magnets for kids is a terrible idea. Just asking for a trip to the emergency room. The book needs to be magnetized and the fraction pieces be just metal.

Whoa, whoa, whoa. Cocaine was only on special occasions, like Fridays. And Saturdays. Sometimes Tuesday, because who can figure out what Tuesday is supposed to be?
Kidding. I've never done cocaine in my life. Largely because I'm terrified of how much I'd probably like it.
Visualizing doesn't mean you understand what's going on. You can SEE that 1/3 + 1/3 = 2/6 but unless you're taught the fundamentals, you'll likely never understand why it works out that way. I hope this product does more than just visual aid.
Its good, until you have a teacher that wants you to show your work and doesn't accept this. I used to hate math teachers like that, because I do everything in my head.
"Hello, is this the Internal Revenue Service? You owe me...um... 50 million dollars in tax returns" "... we'll have to see your returns and receipts as well as..." "No need for that, I did my taxes in my head! 50 millions dollars please..."
That works up to a point. Then the problems get bigger, more complicated and pretty much impossible to "do in your head". I can add and subtract two digit numbers because I played a lot of darts. Darts gets you very good at doing simple arithmetic while drinking beer. But if I've got a linear algebra 4x4 matrix multiplication I'm gonna get me a pencil and paper... or Mathematica or Wolfram Alpha.
When I taught and even in my current job, I always want people to show their work so that I can give them some credit as opposed to no credit. If I can't see where you went wrong and there's a wrong answer then I can't justify giving you points.
You show the work so you can prove you know how to do it.
I had a chemistry teacher that said the final numerical answer was only worth 5 points... the 95 points were showing the work....
He said, you can get an A in my class if you don't have a calculator.... just identify the values you would have come up with and carry them to the next formula.
same here, somewhat.. but.. as far as I was concerned the equations were so damned easy that trying to explain how I did it was like trying to explain how 2+2=4.. super easy math is hard to make proofs for because it's intrinsic knowledge..
to this day I still can't understand how it was so hard for the rest of the class... they'd fill both front and back of the page trying to answer a single formula pop quiz...
teacher told them they had to box in their answer because it was too hard /cont..
for him to discern the answer from the two pages of nonsense.. which was entirely understandable, but I only wrote the answer, and nothing else, and he gave me a 0 for not boxing it in.. on one hand, yeah, letter of the law rules, but on the other hand.. fuck him, he knows why he made the goddamn rule and it doesn't apply
Which was part of the process... you could do the formulas right, get the wrong answer due to a math mistake and still get 95%... also, you could get partial credit for getting most of it right....
With just a numerical answer, you either get 100% or 0%
It's only hard to learn fractions because it's hard to visualize them. Once you can visualize that ยฝ is just ยผ+ยผ, it's easy to understand how to add ยผ+ยฝ to get ยพ, because you can visualize how they relate and convert.
No offence, but that remains a fairly terrible way to learn fractions lol.
1/4 + 1/4 = 1/2 because 1/4 + 1/4 = 2/4 (combine and add numerator of equal bases) and 2/4 % 2/2 = 1/2. That way of learning actually preps you for the math that is coming next. You aren't learning fractions in vaccum, it is a building block for years and years of primary school math. 1/4 + 1/2 = 1/4 + 2/4 = 3/4 (convert to the same base then add).
Yeah, this particular OP doesn't seem like a bot. Still possible that a spambot randomly pops up with "Easy ways to learn math! shortened.link/spam" though
ok, umm.. and? where did he mention anything having to do with metric or imperial? 3/5 of 10mm is 6mm, if you have a glass with some liquid in it, and the line of liquid is about at the middle you say it's half full.. yes, there's a battle between metric and imperial, but this has nothing to do with it
Your reasoning is backwards. It is like saying "Why is 1 Euro a thing when it just means 1,17 dollar?". You're starting of with your weird unit, which then makes the sane unit broken. Start with a clear number and then make it into fractions and the fraction seems silly. It still always does, but even more so.
It's not backwards, fractions are incredibly useful in math, especially calculus and algebra because you have to keep exact values, rounding will mess up formulas. Only once you get to the final answer do you round, intermediate rounding steps will throw you off.
Now multiply by 5, it's 147/25. Divide that by 3 and you have 49/25. Divide that by 12 and it's 49/300. This is why fractions are used in algebra and calculus, they are easier to play around with, especially in formulas.
It depends a lot in the context, and what you're doing. Exact stuff such as calculus and pure abstract math? Yes. Measuring things? Yeah you're NEVER gonna have an exact fraction there. Never. So it's pointless to use fractions for that if your argument is that they're useful in formulas requiring total precision. Just use decimals since the number is not exact to begin with.
I know, but, good response just the same.. I was thinking of saying it in meters because of this as adding the kilo opened it up for other prefixes, but I wanted to keep it a more normally seen measurement for distances
still wish we could figure a non-arbitrary and simple universal measurement for time so we could make a measurement that doesn't require arbitrary measurements (light speed is universal, but, measuring it by the time it takes an arbitrary planet(earth) to rotate needs improving)

Problem with "learning by visualizing" is that you end up thinking that 1/3 + 1/5 = 1/2 if you don't pay enough attention to the small error.

Or hear me out, we use metric system for small numbers. Ain't nobody know what a 7/32" drill bit is but a 5mm makes total sense.
