What if someone told you that 5+5+5 doesn't equal 15?
Any sane person with a second grand education would call your bluff. But they'd be wrong. At least, according to the Common Core curriculum.
A photo of a student getting this answer wrong blew up on Reddit last week, causing mayhem across the Internet.
The "correct" answer to solving 5 times 3 would be 3+3+3+3+3.
Supporters of Common Core say that adding 5 groups of 3 together is correct because that strategy will help students once they reach more advanced math.
Back in September, a dad wrote a check in "Common Core math" to show how strange some of the strategies are.
And Common Core has become a hot button issue in the GOP presidential election. The Donald has come out against the academic standards while Jeb! has long support them.
