Who Cares

Who cares about this? When am I ever going to use this in my live?

Very good questions. A few things to think about...

(1) Just because you don't use it now, doesn't mean it won't be useful later on.

(2) Some math you will NEVER use again, BUT...
How do you know what job or career path you will want to follow down the road.
Almost every job requires math and anything dealing with science and technology will need a strong mathematical background.

(3) Not all math is learned to prepare you for shopping and building a shed in your backyard.
Find the pattern in the Fibonacci Sequence.  1, 1, 2, 3, 5, 8, 13, 21, 34, ___, ___, ___,
Why is it important to learn to analyze numbers and look for patterns?

(4) If the calculator can do it, why should I have to do it on paper?
Great question. Once you master how to do it on paper, you should move to the calculator.
Later in middle school and beyond, calculators will be used more often.
While long division is not extremely fun, it is good for learning multi-step problem solving, trial-and-error, and perseverance... all useful for algebra.
