Class Topics: 09.30.13

In Common Core Math Six today, students in 1, 3, and 4° reviewed combing like terms from the previous Friday.  Once that was completed, Mr. Giomini introduced and had students work with Lesson 2.10: Equations and Their Solutions.  During this lesson, students were introduced to the terms equation and solution.  Problems such as the one below were discussed and solved:

Stephen wants to buy a new snowboard for Mr. Giomini.  He currently has $119, which is $56 less than he needs.  Write an algebraic equation to help determine how much money Stephen still needs in order to purchase the snowboard for Mr. Giomini.

 Students in 2° reviewed GCF and LCM before progressing to Lesson 2.7: Variables and Algebraic Expressions. In this lesson, students learned about the terms: variable, constant, algebraic expression, and evaluate.  Mr. Giomini modeled problems such as the ones listed below:

• n/2 + n for n = 4
• Bella has n quarters.  You can use the expression 0.25n to find the total value of her coins.  What is the value of 18 quarters?

Today's Learning Goals: The student will be able to...

• 1, 3, and 4°:
• determine whether a number is a solution of an equation.
• 2°:
• substitute a given value into an expression.
• evaluate an expression for a given value.

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

• 1, 3, and 4°:
• Lesson 2.10 Problem Solving and Challenge.

• 2°:
• textbook page 94: 1- 9, 18, 29, and 30.
