Computation x Problem-Solving = Success
Q.
Why do we worry so much about math instruction, anyway? Can't they just use
calculators and computers?
Of course technology is good, and of
course calculators and computers are a standard tool that all students should
know how to use. They're fine for daily use for algebra and beyond.
But many of today's grade schools
are letting small children use technology at the expense of their own brain
development. Wanting to look up to date, the primary grades have tended to copy
the secondary grades in math instruction. That is a mistake.
Abandonment of mental math training
– no more memorizing math facts, no more oral drills, no more paper-and-pencil
computation sessions – denies kids the skills they need to be really good at
math.
American kids used to rule the world
in both computation and problem-solving. We've lost ground in both areas,
particularly in computation, in recent years. When the basics go, it doesn't
take long for the higher-level thinking skills to go. Since they're the
ones required for original and creative
use of mathematics in science and business, that's scary for our future. We may
be losing our edge.
The secret to numerical and logical
success in math class and beyond is being able to do math quickly and
accurately in your head. That's where "numbers sense" comes from. That's what
kids need.
Good math problem-solving ability
comes from tussling out a math problem by yourself. When students in the
primary grades "do projects" in groups instead of spending "time on task" alone
with paper and pencil, they become weak, dependent thinkers, able neither to
compute confidently nor creatively solve problems.
This is why grocery store clerks
can't make change: their teachers simply didn't make them do a lot of "reps,"
memorization, math drllls and games, flash cards and other mental math
practice.
"Math by machine" can wait. Kids'
minds need math first.
