Is It Already December? Topics for December 1st

Algebra I

Today we discussed
We discussed two different methods for factoring polynomials - using the GCF and factoring by grouping.  One tricky piece involved expressions that are opposites of one another.

Recall:  (5 - y) = -1(y - 5)

Pre-Algebra

Today we discussed
We figured out how to turn a repeating decimal into a fraction.  Repeating decimals are actually rational numbers!  Also, we reviewed adding and subtracting rational numbers that are in the form of decimal numbers.  Remember, the rules for adding and subtracting integers apply to rationals:

* When adding Rational numbers:
            -->  If the signs are the same, add and keep the sign.
            -->  If the signs are different, subtract and keep the sign of the nubmer
                   with the greater absolute value!


Sections Covered in Textbook
