The Graph Paper
a grid with a handful of thin pretzels. A "grid" is simply a network of
horizontal and vertical lines. How many "squares" can you make with pretzels?
When you've made the biggest grid you can, then eat it. For a drink, try a
glass of tomato juice and "stir" it with a pretzel!
One piece of graph paper; there are
several sizes of squares;
select square size that's about as
as you make your numbers
It's amazing how many students make mistakes with
addition, subtraction, multiplication and division because they aren't writing
their columns of numbers straight.
They subtract from the wrong digit, bring down the
wrong digit in division problems, and add an extra place in a multiplication
problem that leads to a ridiculously wrong answer.
It's hard to keep columns straight if you're working
with plain, unlined paper. Sometimes, even lined notebook paper allows you to
slant over too far, and mis-compute.
here's the best solution of all:
Just go to an office supply store,
or a school supply store, and choose a pad of graph paper that has squares
about the same size as you make your numbers.
Then either do your math homework
directly on sheets of graph paper, or keep a piece of graph paper under your
scratch paper as you work.
The horizontal and vertical lines
will keep your computation columns in apple-pie order!
