Sorting Activities by Error

Using this approach allows teachers to remediate specific errors their students are making through relevant Classroom Activities. This approach may be helpful when teachers are working one-on-one with a student or with a small group of students who are making the same error(s). 

 

To use this approach, teachers will first have to identify the specific errors students are making using the Error Analysis Tables. Errors are categorized into 5 strands on the Error Analysis Tables: 1) Numbers and Operations, 2) Patterning and Algebra, 3) Measurement, 4) Geometry, and 5) Data Management and Probability. These strands are based on Lynn McGarvey’s work on mathematics learning progressions.  

 

After identifying specific errors, the Error Analysis Table directs teachers to specific Classroom Activities that can be used to remediate them.
