Algebraic Expressions

Learning Intention:  Students will recognize equivalent algebraic expressions; represent the unknown in an equation; use properties of operation to generate equivalent expressions involving addition, subtraction, multiplication or division; identify equivalent number sentences; use symbols for equal and not equal. 

Success Criteria:  Students will be successful when they can recognize equivalent algebraic expressions and use properties of addition to create an equivalent algebraic expression. 

Essential Questions:
- What operation is needed in this problem?
- What are the known quantities and the unknown variable in the problem?
- What does the variable represent?
- What is the correct order for performing mathematical operations?
- How can the properties of operations be used to determine if two equations are equivalent?
- What is the difference between each of the numbers in this sequence?
- What is the rule for this sequence?
