Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.
Big Idea:What are similarities and differences between these figures? What expressions represent the perimeter and area of each figure? Students combine like terms and create expressions to represent the perimeter and area of figures created with algebra tiles.
Big Idea:What are the similarities and differences between expressions, equations, and inequalities? What do students understand? What gaps do they have in their understanding? Students review and take the quiz.
Big Idea:What is going on in the problem? What are you trying to figure out? How can you use variables to represent what is going on? Students apply the skills they have learned throughout Unit 6 to complex tasks.
Big Idea:Hitting The Glass Ceiling... or Floor: Understanding that inequalities describe a type of limitation in a real world situation where you can't go any higher than a given quantity or you can't go any lower.
