The Story
As a math teacher, I always found it fascinating how students would react to the simple question of What's the square root of 400? Some would immediately answer, 20! while others would stare blankly at the board. It was as if this particular problem held some sort of mystery that they couldn't quite figure out.
One day, during class, I decided to dig deeper into this mystery. I asked my students why they found this problem so challenging. One student, who had been struggling with math all semester, said, I don't know. It just seems like there's something more to it than just multiplying 20 by 20. His response made me realize that perhaps the mystery surrounding this problem wasn't about the solution itself, but rather the perception that there was something more complex behind it.
I then explained to my students that finding the square root of a number is simply the opposite of squaring it. In other words, if you square 20, you get 400, and if you take the square root of 400, you get 20. It's that simple!
The Point of View
Empathic voice and tone can be useful in helping others understand and relate to a topic. When it comes to math, many people have a fear or aversion to it. By approaching the mystery of what's the square root of 400 from an empathic point of view, I was able to connect with my students on a more personal level. I understood their struggles and misconceptions, and by addressing them in a supportive and relatable way, I was able to help them overcome their fears and better understand the concept at hand.
The Table Information
The following table provides some important keywords and definitions related to square roots:
- Square root: A number that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16.
- Radical sign: The symbol used to represent the square root, which looks like a checkmark or a V with a horizontal line through it.
- Radical expression: An expression that contains a radical sign, such as √16 or √25x.
