Worth a Letter Grade
I taught math for 10 years. During that whole time, the biggest
causes of lost points on tests or homework were clerical errors, careless
mistakes and not checking work. So I came up with some "wisdom" that I
would offer up on Day 1 and keep repeating until the last day of school. I
tried to keep it light and a bit tongue-in-cheek, but the message is
serious stuff. Following these simple principles can boost a student's
marks by one letter grade or more.
Math Wisdom From Mister L
- "A calculator is a small computer and inside, computers are stupid.
They only do what you tell them."
"Don't punch a problem into a calculator without some idea of what the answer is going to
be and make sure you check the one it gives you."
- "If you copy the problem wrong, the answer will always be..... wrong."
"If you punch in the numbers wrong, the answer will always be.....
"There's often more than one way to do a math problem. The more complex the
problem, the more ways there are to do it."
"Math requires a degree of precision and accuracy that most people aren't used to."
- "Accuracy is more important than speed. Accuracy develops confidence and confidence develops speed."
- "When the students are done with
my math class, they'll all want to be math
teachers instead of highly paid rocket scientists."
