whole number computational fluency articulated to decimal computation
Posted: Dec 11, 2001 3:26 PM

I am the mathematics facilitator for a school district of about 18,000
students. We implemented Connected Mathematics into our six middle
schools 4 years ago. We are beginning the third year of implementation
of Investigations in grades three through five. I am writing to ask
programs.

Our students are now entering middle school with some fluency in whole
number computation. Students are computing whole numbers in more than
one way. However, in many cases, a child may not be familiar, or to
say the least, fluent with the traditional algorithms. As students
are learning to multiply and divide decimal numbers in 6th and 7th
grades, we are struggling to find efficient methods other than the
traditional algorithms. Problems like 3.45 x 2.8 can easily be
estimated, but how do you transition students who do not know the
traditional algorithm to accurately compute a problem like this? The
efficient methods from whole number computation don't seem to work
here. Another example would be 0.453 divided by 2.6. I am NOT
punching criticism at invented methods. I see the power and
appreciate the approaches. I am sincerely asking the question.
