HOME LEARNING:
Pre-Algebra - Periods 1A and 4A, 5B and 6B- 
Finish researching how to simplify and evaluate negative exponents.  Complete worksheet that was given in class.

MJ1 Advanced - Period 3A and 7B
Finish Practice Test

Attention Pre-Algebra Students - below are explanations of monomials, binomials and polynomials.  Some students are still haveing difficulty with "What is a nomial?"  I believe this information will help and I will discuss further in class.
A monomial is the product of non-negative integer powers of variables.  Consequently, a monomial  has NO variable in its denominator.  It has one term.  (mono implies one)
13,    3x,    -57,     x²,     4y²,     -2xy,  or  520x²y²
                 (notice:  no negative exponents, no fractional exponents)

A binomial is the sum of two monomials.  It has two unlike terms. 
(bi implies two)
3x + 1,    x² - 4x,     2x + y,    or    y - y²


A trinomial is the sum of three monomials.  It has three unlike terms.   (tri implies three)
x2 + 2x + 1,      3x² - 4x + 10,       2x + 3y + 2


A polynomial is the sum of one or more terms.  (poly implies many)
x2 + 2x,      3x3 + x² + 5x + 6,       4x - 6y + 8
