Errors are classified as either Number Fact Errors, Slips (lapse of memory) or Bugs (systematically using an inaccurate procedure or strategy.)
Today, I'm working on tools to help students both write analysis of peer errors and increase awareness of common computational mistakes. I want to create a classroom language with easy to identify graphics that will help children organize their strengths and weaknesses.
So, I'm making BUGS that use common errors.
This BUG thinks that all numbers in a word problem should be added. No matter what! Now, I need to make a fly swatter with the CORRECT strategy.
Here's the BUG that thinks it's OK to start from the left or the right. Or, to work from the bottom up.
Look for more of these BUGS with instructional activities to be posted soon.
