Analyzing Math With a Mathematician’s Eye…4 Types of Errors

Karissa copy

The students have been working on adding, subtracting, multiplying, & dividing decimals in groups in class lately.  Students practiced looking at their math work closely with a mathematician’s eye.  What does this mean you ask?  Well, anytime a student encounters an error on class work, they are asked to identify why it was incorrect.  They “dive” into the 4 types of math errors and diagnose why their answer was marked wrong by using the following infopic!  (Infopic: a picture that informs, shares information in a brief, but thoughtful, deep way! Phrase coined by Tony Vincent-a top notch Techie Teacher)  Each of the students made their own infopic to refer to when analyzing their math!  We found that the closer we look at our errors and identify why we got the error to begin with…we don’t make the same error twice!  Check out a few of them below.
