Class Topics: 10.14.13

In Common Core Math Six, students in 1, 3, and 4° reviewed the Weekend Practice with an answer key provided by Mr. Giomini.  Mr. Giomini introduced Lesson 3.4: Subtracting Integers to the students by viewing a video and providing examples on the board.

Students in 2° received their Chapter Two posttest back from Mr. Giomini.  The strengths and weaknesses of the assessment were discussed as a class.  Mr. Giomini then had the students play some games to help prepare students for tomorrow's Chapter Three pretest.
Today's Learning Goals: The student will be able to...

• model the subtraction of integers with counters and a number line.  (1, 3, and 4°)
• evaluate an expression with integers.  (1, 3, and 4°)
• evaluate an algebraic expression for a given value.  (2°)
• combine like terms to simplify an algebraic expressions.  (2°)
• solve one-step equations using addition, subtraction, multiplication, or division.  (2°)

For Evening Practice, the student is expected to...

• 1, 3, and 4° -
• complete Lesson 3.3 Challenge, Lesson 3.4 Practice C and Problem Solving 
• Google Form
• 2° - 
• preview material for Chapter Three by completing the two Khan skills listed below:
• Absolute Value
• Points on the Coordinate Plane
