  • Students who received a score of 70% or below on Learning Target quizzes may re-take them to improve their score and to receive a passing grade showing that they understand the learning target. The cut-offs for re-takes are:
    • LT #2.6 - [Translations & Reflections] - students who received a score of 5 or less (out of possible 8 pts.)
    • LT #2.8 - [Order of operations] - students who received a score of 5 or less (out of possible 8 pts.)
    • LT #2.9 - [Commutative, Associative, & Distributive properties] - students who received a score of 11.5 or less (out of possible 16 pts.)
    • LT #3.1 - [Rational vs Irrational numbers] - students who received a score of 4 or less (out of possible 6 pts.)
    • LT #3.2 - [Percent & Ratios] - students who received a score of 8 or less (out of possible 11 pts.)
    • LT #3.4-3.5 - [Proportional Reasoning] - students who received a score of 8 or less (out of possible 11 pts.)

In order to do a re-take, students need to KEEP their old quiz, and BRING it in, with the correct answers (with explanations) on a SEPARATE FORM on the items they missed. [RETAKE FORMS AVAILABLE IN MR. USEM'S ROOM, or are available as a downloadable PDF document on his WEBPAGE] This will qualify them "ready to re-take" the quiz. Re-takes are to be done outside of regular class time, and can be done before-school, after-school, during recess, or during study-hall in Advisories on Thursdays. Students should make arrangements with Mr. Usem to do the re-takes. Students will have at least 2 weeks from when the quizzes are handed back to complete the re-take.

  • (Deadline for LT #3.1, 3.2 & 3.4-3.5 is: Tuesday, Jan 10)
