Kindergarten is Too Young for That Kind of Stress

I don't post about current events and issues very often on here, but today I stumbled upon a story on ABC News that I really just couldn't let pass.
A small primary school in New York is in the news for a decision it made regarding its kindergarten's annual parents' show. According to the article, the school's principal canceled the parents' show so the kids could focus on their studies and college preparations. You can read the rest of the story here.
Please tell me I'm not the only person who thinks this is ridiculous. The principal claimed that the show was canceled in order to make up for time missed due to winter weather. I can understand that to a degree, maybe for older grades. But for kindergarten? Why? The kids are five and six years old. They need to have fun and be in a low-stress environment. 
The best part? The article cited that the students would spend their make-up class time "working on SAT flash cards." Joke or not, do kids that age know what the SAT is? Have they even heard of it? I can guarantee that, at five years old, I didn't even know what was for lunch the next day. Unless it was chicken nugget day. Everyone knew when it was chicken nugget day.
At that age, learning through fun activities is crucial. My early teachers (preschool and kindergarten) had the philosophy of, "If we can sing it, we can learn it." I remember singing the months, days of the week, colors, ABCs and more with fun hand motions to go along. Other educational activities included matching games and worksheets that involved puzzles and lots of coloring. I learned my first math by coloring 5 red apples, 3 oranges and 1 green apple, and then counting the total.
Even in eighth-grade algebra, I learned the quadratic formula by singing it to the tune of "Frere Jacques." Believe me, it worked. I still sing it to myself on the rare occasion I need to know that formula for something. 
School shows have been happening for years upon years. In a lot of cases, the kids sing songs about things they've learned in lessons and get to dress up. I remember Thanksgiving shows from my early elementary school days when we sang about the Mayflower, the settlers, the Native Americans and the first Thanksgiving. My mom has told me about little shows her kindergarten class did that involved small musical instruments like triangles, woodblocks, tambourines and the like. Another year, they did a costume parade. 
There is no reason for kids that young to experience that kind of stress. Yes, our students should always strive for success, but within reason and balanced with fun and comfortable environments. What reason is there to teach kids SAT skills in kindergarten? Let them be young and have fun.
I understand that the world is full of competition and that one day, those skills will be needed. But I do not think that starting that young is a good idea. At that age, kids do not know how to handle that kind of pressure, and they shouldn't. If we start them that young, it will only build and could become insurmountable. That is not the educational future I want my kids experiencing. 
Plus, putting on a show teaches kids a whole different set of skills. You can't teach them to stand in front of an audience or build their confidence with a worksheet or test. 
And don't even get me started on the lack of arts education. That's something entirely different.  So for now, if my kids' elementary school cancels their kindergarten parents' show for SAT prep, you can bet I'll be the first person to sign that petition. Kids need time to be kids. They have plenty of time to grow up.
