Instructors:	Mr. Ahmed Hefny
Attendance:	Ayyan, Aiden, Omar, Areej, AbdulRafay,
Homework:	Read: Chapter 5 - Sections 5.1-5.4. Go through examples, especially section 5.4 (word problems). Problems to solve: 5.2.3, 5.2.6, 5.3.6, 5.4.6, 5.4.8, and 5.4.9
Class Activity:	Chapter 5 - Sections 5.1-5.4
Concepts:	- Introduced the notion of expressions, terms, factors, constant and variables. - Differentiated between equations and equivalences.  Equation: An equation is a statement that two expressions are equal. Solving an equation means find the values of the variables that makes an equation true. Equivalence: An equivalence is statement that two expressions are equal for all possible values of the variables. - Solving a linear equation in a single variable. - Translating a word problem into an equation.
Student Difficulties:	Students are getting better at mathematical modeling (translating a problem into an equation) but more practice is needed.  Please try the examples and exercises of section 5.4.  Remember: solving an equation is easy. Coming up with the right equation is the harder part.
