8th Grade Math

Welcome to Eighth Grade Math with Mr. Scapellati


Summer Math Work - All must complete the vocabulary assignment.  A math computation packet is to be completed as well.  Both are posted below.



Summer Vacation Assignment 
– due September 2017 (1st day)

 

Each student is to purchase two 5-subject spiral notebooks for math.

The first section, of your classwork notebook, should be labeled “Vocabulary.”

Vertically fold the pages in Section 1 down the middle, forming 2 columns.

Given the list below, write the word and give its definition in the left column and provide an example of such in the right column next to its meaning.  This is to be handwritten.

Please complete alphabetically.
