TKES 1, 2, 3,4,5, 8,10

Standard/s:

MGSE9-12.A.REI.6 Algebra 1 Standards – Substitute Systems of Equations

Learning Target:

I will solve systems of equations by substitution.

Success Criteria:

• I can solve an equation for a variable.
• I can substitute an expression into an equation to solve for a variable.
• I can remember and understand the Box Box Circle Drag mnemonic.
• I can identify the solution
• One solution – (x, y)
• No solutions – variables cancel out (false statement)
• Infinitely many solution – variables cancel out (true statement)

Introduction/Connection: 

Pirate Prep

Review steps of solving by subsisting systems of equations. 

DIRECT INSTRUCTION:

None.

Work Period  (We Do, You Do)

Students learning by doing/demonstrating learning expectations.  Describe the instructional process that will be used to engage the students in the work period.

TKES 1, 2, 3, 4, 5, 7. 8,10

GUIDED PRACTICE: 

We will go over solutions from yesterdays worksheet. Solutions will be shared. Students will split into two groups with teachers to complete class work. Work on page 277 in Explorations in Core Mathematics workbook.   

INDEPENDENT/COLLABORATIVE PRACTICE/DIFFERENTIATION:

Students will come to the board and share solutions with the class. Class discussions will arise when necessary. Scaffolding throughout lesson and applications will be provided for rigor. Students will work with pairs at some points throughout the assignment.

Closing  (We Check)

Describe the instructional process that will be used to close the lesson and check for student understanding .
