Welcome to Common Core Algebra with Mr. Scapellati!

**Common Core Algebra is a rigorous high school level course which concludes with students sitting for the administration of the Algebra 1 Regents Examination in June. Placement in this course is based on the demonstration of strong math skills/potential in both sixth and seventh grades. Successful completion of this course results in appropriate high school credit.

**Summer Math Work Part 2: MATH VOCABULARY**

*Summer Vocabulary Assignment – due Friday, September 6, 2019*

Each student is to purchase a 3-subject notebook used solely for Math Vocabulary.

You will have numerous checkpoints throughout the year, where each given word is to be accompanied by an appropriate definition and a sound example. Vertically fold the pages down the middle, so that two columns are formed. The word and its definition are to be located in the left column, while the example is to be provided in the right column (next to the word/definition). All is to be neatly handwritten and completed alphabetically. Remember to use valid resources when researching.
