I saw that. What a useless waste of time and energy. I do not have a brain wired for math or for the long, drawn out explanation given by the teacher.

Neither do most first or second grade children.
One of the most annoying things about Common core advocates is that they will go on and on with how superior Common core is because it promotes “critical thinking”. The teachers are expected to give these long drawn out explanations using new edu-speak terms, which more often than not, confuse most students. Some kids will understand the process when it is taught, but a lot won’t. They will have simply memorized the process that is required by their teacher and the curriculum. So much for “critical thinking”. Meanwhile what the students have learned to do is to turn a 10 second math problem into a 3 minute math problem. And this is considered progress.
I DO have a brain wired for math and the teacher's explanation is full of holes and ASSumptions about prior knowledge the student has.
CC WAY over complicates math. The best route is to have the kids memorize their addition and multiplication facts.
With those in hand (or rather head) they can figure about anything out in seconds.
Especially when they realize that they can just reverse the addition to subtract and the multiplication to divide.
With the fact memorized, you don't need to worry about procedures and techniques and having a pen or pencil and a ream of paper on hand to calculate things out long hand.
