Grade Level7th/8th
Week #Q1W6 Sept. 21-24
Unit of InstructionAlgebra Equations and Inequalities
Standard(s) Taught

MAFS.912.A-REI.2.4b – Solve quadratic equations in one variable by inspection as appropriate to the initial form of the equation.

MAFS.912.A-CED.1.2 – Create equation in two or more variables to represent relationships between quantities, graph equations on coordinate axes with labels and scales.

MAFS.912.A-REI.4.10 – Understand that the graph of an equation in two variables is the et of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).

Learning Targets and Learning Criteria
  • solve equations using the zero product property, for example (2x – 5)(x + 4) = 0
  • graph equations on the coordinate plane the represent all possible solutions to a real-world problem using appropriate labels and scales.
  • create a graph where the ordered pairs are solutions to the equation.
  • verify that any point on a graph will result in a true equation when their coordinates are substituted into the equation.
Classroom Activities

Tuesday:  

Bellringer:  Solve literal equation A=1/2bh for h.

Whole Group:  Go over test.  Use test as a study guide for retest on Wednesday (tomorrow)  Take notes for ISN – Page 10 Compound Inequalities Compound Inequalities Notes

Small Group: Watch Khan Academy Videos on Compound Inequalities (these are assigned in Khan Academy)

Independent: Compound Inequalities K.13, K.14 (70%)

Wednesday:  

Bellringer:  Solve absolute value equation |5x-10|/2 = 50.  Solve Literal Equation 4x + 7y = z for x.

Whole Group:  ISN – Page 10 Compound Inequalities (All Things Algebra) (check in class). Compound Inequalities Notes

Small Group: IXL (Algebra) K.13 & K.14 (compound inequalities)(70%)

Independent: IXL absolute value L.1, relate the graph of an equation to the solutions I.10, and rearrange multivariable equations I.11.  finish for homework

Thursday/Friday:

Whole Group: Take District Interim Assessment (DIA).  Grades will be recorded in grade book as a summative grade. 

Complete work after DIA testing.
