Mr. Goldberg has been teaching a unit on fractions. He was pleased that all of his students seemed to quickly
master adding and subtracting two fractions. However, when he began teaching the students how to multiply
fractions, a small number of them did not readily learn the content. But after a quick mini-lesson, it appears that
all but three students seem to understand how to solve the problems. One of these students, Wyatt, seems to be
really struggling. Mr. Goldberg determines that he needs to collect some data to help him decide what type of error
Wyatt is making so that he can provide appropriate instruction to help Wyatt be successful. To do so, he decides to
evaluate Wyatt’s most recent independent classroom assignment.
! Assignment
1. Read the Introduction.
2. Read the STAR Sheets.
3. Score Wyatt’s classroom assignment below by marking each incorrect digit.
4. Review Wyatt’s scored assignment sheet.
a. Describe Wyatt’s error pattern.
b. Discuss any exceptions to this error pattern. What might these indicate?
5. Based on Wyatt’s error pattern, which of the two strategies described in the Addressing Error
Patterns STAR Sheet would you recommend that Mr. Goldberg use to remediate this error?
Explain your response.
