Regrouping/Borrowing/Carrying...hmmm...sounds confusing.
What areyou(we) talking about? It is not surprising that
students become confused.Some 'experts' would insist you
do not say borrowing and carrying and that using the term
regrouping makes things perfectly clear, however,
I have not witnessed this supposition!
During the last few weeks, students have been introduced
to this strategy for adding and subtracting and the same
students who had problems with mental arithmetic
strategies continue to have problems with this strategy.
No surprise there!
Another element that has added to the confusion for some
students is that you can write questions horizontally
and vertically.Some 'experts' frown on writing questions
vertically while the text I am using writes them both ways,
but reserves writing questions vertically for three-digit
subtracting with regrouping.
I can see that I will have a busy summer getting all of
this sorted out so that I can present ideas to students
in a logical, comprehendable and comprehensive manner.
How did a simple basic skill like adding and subtracting
become so complex and confusing?
What's next? Restructure, review and present skills in
problem-solving situations.
