Unit Scale: 

4.0Through independent work beyond what was taught in class, students could (examples include, but are not limited to):

•compose and evaluate how many babysitting hours are needed along with weekly allowance saved to purchase a bicycle. 

•determine how many friends they can invite to an amusement park depending upon the ticket costs, food purchases and taxes with a limited budget

3.0 

The students will:

•use variables to represent quantities in a real­world or mathematical problem and construct simple questions and inequalities to solve problems by reasoning about the equalities. 

 a.Solve word problems leading to equations of the form px+q=r and p(x+q)=r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach

2.0

The students will:

*determine the meaning of symbols, key terms, and other equation and expression specific words and phrases as they are used in a specific technical context relevant to grade 6­8 texts and topics 

*understand the use of variables

*translate written phrases into algebraic expressions.

*translate algebraic expressions into written phrases.

*perform the four basic operations using rational numbers.

*apply the order of operations to evaluate expressions.

*understand how to apply the Commutative Property and the Distributive Property to solve equations containing integers.

*solve one­step equations involving integers.

1.0 With help, the students will have partial success at level 2.0 and level 3.0 content and recognition of academic vocabulary (see below).
