Error Patterns in Computation

Book excerpt: This is the only supplemental text of its kind that guides teachers to identify children's common mathematical error patterns and to gain insight regarding why a child may have adopted an incorrect mathematics procedure. Revised to link content to the new NCTM Standards, the tenth edition emphasizes the meaning of operations and appropriate methods of computation. As in previous editions, the book retains its focus on placing paper and pencil instructional activities within the context of problem solving. NEW! Places emphasis on diagnosis as a part of formative assessment. Teachers can use varied approaches to diagnosis before instruction and also as they intervene during instruction. Open-ended assessment and problem writing are two procedures illustrated.
