Scientific Notation always has a coefficient that is between 1 and 10 multiplied by a power of
ten.

Write this in the “Proper Scientific Notation” section of your foldable:
If the coefficient is too large, you need to move the decimal back to the appropriate space and
add that amount to your exponent.
38.2 x 103 should be changed to 3.82 x 104
If the coefficient is too small, you need to move the decimal forward to the appropriate space
and subtract that amount from your exponent.
0.012 x 105 should be changed to 1.2 x 103
