Turned-in:    nothing

Homework:   None

Notes:  Our first Learning Target Quiz (#2.1 & 2.2) coming up Friday

REMINDER:  At most, homework is designed such that students should spend 30-40 minutes maximum of focused effort on their homework assignments on any night. (*Please note that not all assignments are designed to take 30-40 minutes, that is only the maximum time... most homework assignments should be able to be accomplished in less time.) If an assignment is taking longer than that, students should stop working, and come in with the work, as completed, for class the next day to discuss with the teacher the issues the student may be having that is making it difficult for him/her to complete the assignment
