2. Admin Notes: It is imperative that you if you did not earn at least an 80% on your quiz day 3 (Algebra I)- you must come for extra help! Your first and last name and block must be on each paper you turn in! If your paper says “WHO,” then you must bring it back to me with your name on it. Honors: online pearsonsuccess.net assignments due Friday (there are no late online grades) Remember to assemble your storybook for your first class grade!!!!! Tab p. 7 in your storybook to begin using as a reference
