For education expenditure, US spends about $1.1T, of which only $0.11T comes from federal gov't and $1T from state/local gov't in FY2018. It's pretty much ALWAYS been the case that local/state gov't's pay for education expenses (often tied to property taxes).
The national defense budget for FY2018 is $0.87T and comes out of the federal budget only. Comparing the two at federal level makes no sense.

But the fact that the US Federal government always find money to feed its military while cutting the other departments [1] (including education) doesn't change the underlying fact that Education has a lesser priority than the Military in Washington DC.

If your argument is that education should be a constitutional right, and thus funded by the federal government, then that's a different argument than simply "finding the money." Is that the argument you're making?
Countries like Finland, South Korea which routinely rank top in various international tests and studies spend far less and achieve much better results than the US, so the problem here isn't just about funding.
A quick googling says there's 50.7 million public school kids in the country, you're saying we only spend ~$1,300 per kid? Yeah, that's clearly wrong, you're either making that number up or are quoting the wrong number. And that's not even taking into account any university or adult education spending.
The Department of Education is administered by the United States Secretary of Education. It has under 4,000 employees (2018)[1] and an annual budget of $68 billion (2016).¹
More info at the Education Departments website.²
I don't think that's the right number though? That's just what the Education Department spends each year administering education? The FY 2019 Education Budget Fact Sheet² goes on to say:
"The Budget supports $129.8 billion in new postsecondary grants, loans, and work-study assistance to help an estimated 11.5 million students and their families pay for college
So there's clearly more funds being directed to education than just the $68B.

Additionally, the US spends more than almost all OECD countries [1]

Edit: as noted by a comment bellow, this is only the budget at the Federal Level
