# What’s Happening in Math.

Math B has been working on Prealgebra standards such as these:

• I can write numerical expressions involving whole number exponents.
Ex. 34 = 3x3x3x3
• I can solve order of operation problems that contain exponents.
Ex. 3+22 – (2+3) = 2
• I can use numbers and variables to evaluate expressions.
• I can translate written phrases into algebraic expressions.
• I can identify parts of an expression using mathematical terms (sum, term, product, factor,
quotient, coefficient).
• I can substitute specific values for variables

Math A  has been working on our number sense by extending the number line to include negative numbers.

• I can use integers to represent quantities in real world situations (above/below sea level,
etc).
•  I can explain where zero fits into a situation represented by integers.
•  I can identify an integer and its opposite.
•  I can identify a rational number as a point in the number line.
• I can identify the location of zero on a number line in relation to positive and negative
numbers.
• I can reason that when only the x value in a set of ordered pairs are opposites, it creates a
reflection over the y axis, e.g., (x,y) and (x,-y).
• I can recognize opposite signs of numbers as locations on opposite sides of 0 on the
number line.
• I can recognize that when only the y value in a set of ordered pairs are opposites, it
creates a reflection over the x axis, e.g., (x,y) and (x,-y).
