Why is Math Taught Differently Now?

What is “new math” or Common Core math? One example is this “new math” check floating around the internet. Do you know how much is it written for?


According to an article by Hemant Mehta, the check writer (Doug Herrmann) didn’t actually understand what he was talking about so it’s for two different amounts. In the box where you write the amount, the ten-frame is wrong—it’s written as an non-existent eight-frame. However, if some logic is applied, the amount is $8.43. The line where you write out the amount in nice cursive? It’s written with a correct ten-frame box—$10.43. By the way, Mehta assumes the system of 0’s/circles and X’s is $0.43. He’s not really sure since the system appears to be Herrmann’s own creation. I assume it’s based off separate method for illustrating/explaining math.

Don’t understand ten-frames? I highly recommend reading Mehta’s article, The Dad Who Wrote a Check Using “Common Core” Math Doesn’t Know What He’s Talking About. Mehta explains what a ten-frame is, as well as how to use it. He also reinforces that Common Core is a set of standards, not a curriculum .Article Bonus: Mehta compares new math to Food Network’s Chopped.

So, why is math taught differently now? You need your brain to think, not to compute. That’s what the device(s) you carry around all day are for! “New math” or “common core math” teaches students multiple methods and the reasoning behind it before getting to shortcuts. Plus, you use it every day to make change (if you still use cash!)
