One adage that I keep telling myself is as stated in the title above: Practice makes perfect. Want to be good at computer programming? Practice! Want to be good in writing articles? Practice! Want to be good at web development? Taking picture? Problem solving? Practice, practice, practice!
And with my son studying first-grade math now, the same maxim holds true to him as well---"Practice makes perfect, son," I keep telling him.
Don't get me wrong; he is good a math. In fact, he is a GATE student, an avid reader with a keen interest for scientific facts, and a future ocean animal scientist slash doctor slash inventor, whatever his final decision be. But still, silly math mistakes happen, and one way to prevent it is to practice more. I had him done more additions and subtractions, and I DO see the result of the drill.
So what tool did I use? Just a simple Excel sheet printout! With formulas, of course---this is a perfect 'practice' opportunity for me too, don't you think?
