October 27th Class Topics

Algebra I

Today we discussed
We expanded our discussion of open sentences to include solving equation and inequalities involving absolute value.  REMEMBER:  you have two cases to solve with absolute value:  the positive case and the negative case.  Absolute value open sentences really involve two separate problems.  
Sections Covered in Textbook

Pre-Algebra

Today we discussed
We worked on defining bases, exponents and powers as well as what prime and composite numbers are.  We completed a Sieve of Eratosthenes (click here for more information) to determine all the prime numbers between 1 and 100.  You can download a 1-100 chart here if you want to try the exercise again, or share with your parents.  THINK:  are the numbers 0 and 1 prime or composite?  How do you know?   We also then discussed prime factorization of monomials.

Sections Covered in Textbook
