Kids Pack of 86 Division Flash Cards
Two out of five stars
I was astounded
when I opened this package and began looking through the cards. The first were
standard division operations with the correct values on the other side in the
standard structure of flash cards. Then I encountered one where 2 was being
divided by zero, I flipped it over and went into a moment of brain lock. The
value was listed as ZERO! This is such a colossal mistake, for it is drilled
into students very early that division by zero is not allowed. Or in mathspeak,
is undefined.
While it is
only one mistake, it is a major one. So even though 171 of the sides of the
cards may be right, the failure on the one I cite seriously demeans the entire
package.
