This shit is the very reason why American "education" is a joke

I don't see what this is supposed to teach.

I am glad I am no longer in school. I have honestly learned much more after graduating than I ever did in school.

Not only that, but I've learned more in a few weeks of college than 12 years in public schooling. Being made to work and holding a person responsible is the direction that needs to be taken, not this B.S where grades are replaced with things like "satisfactory and unsatisfactory". Education has turned into babying and shielding when reality is that you will be expected to complete a task or be in serious trouble

You guys never used number lines in school?

Are you saying you actually understand what's in the OP?

I don't see what's so difficult. Jack forgot another "10" to subtract somewhere along the line.

The answer is 111. Jack got 121. Seems pretty obvious.

We had those neat little green foam blocks.

What exactly is the problem here?

Are you fuc­king allergic to numberlines?

number lines are a retarded, impractical method of learning subtraction for all the special snowflakes who ate glue back in kindergarten, it's never used in the real world and never should be used.

Well, obviously. But let's not pretend that number lines are anything new, nor are they used in anything above 3rd grade math. It's not like we're teaching kids algebra with number lines and shit.

the farthest number lines should be used is kindergarten, that's the issue. By that point you should be able to grasp the concept of subtraction and addition and be able to scale up without the usage of a number line. Once you pass basic subtraction of 20-5 and the like, numberlines have no place in education.

I just picked 3rd grade for an example. I have no idea when they're used until. US math education is FAR FAR behind where it should be.

edit: woops. Didn't look who I was replying to.

I find it interesting that it's pretty much only conservative sources talking about it

That's because the correct answer isn't on the number line. It clearly states that Jack got the answer wrong, so the wrong answer is displayed on the number line.

That's what's unnerving.

Either the parent is admitting they can't see there's a fault in the number line, or they can but just don't know what it is.

Oh I see where you're coming from. I think I confused something along the way.

Well, CommonCore is a liberal policy. Why would a liberal source link to something that goes against the policies of politicians they support?

Just because it's supported by liberals [and a number of conservatives, mind you] doesn't mean it's some attack by liberals to try to inject the public school system with their positions.

I'd love to see what conservatives would propose we do to reform schools, but they haven't proposed fuc­k-all.

I think so, but that wasn't the focus and was only used as an alternative to simple 9-3=6 subtraction. Now schools are placing these CommonCore concepts ahead of 6+3=9 and 5*2-4=6
