Ch. 4 Test Thursday 11/17

Hey everyone,

Just one more week before Thanksgiving! It will be a busy one. Ch. 4 tests (6th grade and 7th grade) are Thursday, November 17th. These tests are 100 points.

I passed out very detailed review sheets today in class. Please pay close attention to these- the test overs a lot of information, but I also let you know how many GCF and LCM problems there will be (don't spend all your time on these!).

General Reminder: All tests must be signed regardless of grade- that is my class policy and has been and will be in effect all year. Work deficiencies are issued if tests are not signed/returned as directed regardless of grade. The students are well-aware of this policy.

6th grade: Spiral due Tuesday. Test Thursday. Several students need to return work deficiencies Monday.

7th grade: Spiral due Tuesday. Make sure you have written change in problem 5: change division sign to addition sign. Test Thursday.

Mid-term study guides for 7th grade will go home Friday, 10/18.

Have a great weekend everyone!
