Unit 1: Essential Skills & Rational Numbers A paper copy of this outline is distributed to students at the start of the unit. While we will attempt to stick to this schedule and assigned exercises, some modifications may be necessary. In that case, students will be informed in class. Students can use the unit outline as a checklist to ensure that they have completed all topics and assigned work in preparation for the unit test. *Note: Unit 1 Test is postponed until Mon. Feb. 22 due to Winter Carnival on Friday.
