Welcome back! I hope everyone had a great week off, and come back ready to get back to work. Before break, we finished up our work on Solving Linear Systems by Substitution (Learning Target 4 from Unit 4). Now we are starting our last learning target of Unit 4. For the next two weeks we will be learning how to solve linear systems of equations using elimination.
MONDAY Learning Target: Reviewing how to solve one step equations and solving 2 variable equations after substitution (plug and solve). Success Criteria: Students are successful if they can: - solve an equation using one operations (addition, subtraction, multiplication, and division) - substitute in a number in place of a variable and solve for the other variable (Solve 3x + 4y = 11 when x = 1) TUESDAY and WEDNESDAY Learning Target: Solving Linear Systems of Equations Using Elimination (no multiplication required) Success Criteria: Students are successful if they can: - line up the x and y variables - use addition to combine 2 equations into 1 equation in 1 variable and solve for that variable - substitute the number back into one of the equations and solve for the other variable On Tuesday we will do notes and guided practice and on Wednesday students will have a chance to practice on their own. THURSDAY and FRIDAY Learning Target: Solving Linear Systems of Equations Using Elimination (multiplication required) Success Criteria: Students are successful if they can: - line up the x and y variable - use multiplication to ensure that one variable will drop out of the system - use addition to combine 2 equations into 1 equation in 1 variable and solve - Substitute the number back into one of the equations and solve for the other variable On Thursday we will do guided practice to show some different multiplication scenarios and on Friday students will have a chance to practice on their own.

This week we are focusing on mastering how to solve linear systems of equations using substitution. On Thursday we will have a quiz on solving by substitution so we can wrap us this learning target before our mid winter break.
MONDAY - THURSDAY LT4: Students will be able to solve linear systems of equations using substitution SC: Students are successful if you can: 1) solve for x or y in one of the equations (isolate) 2) substitute into the other equation and solve for the unknown variable (x or y) 3) substitute your number from step 2 back into the isolated equation and solve for your other variable Whoa! I know that seems like a lot, so we are taking substitution slow and doing several guided practice and partner practice in class. Monday - Playing Substitution Kahoot! Tuesday - Partner Math Lib with Substitution Wednesday - Study Guide for your Quiz THURSDAY QUIZ on Substitution Show what you know about solving linear systems of equations using substitution FRIDAY Review and wrap up before our Midwinter break. This will be a make up day for any students that need to take the quiz, finish SCANTRON, make up missing work, or complete an extra credit Algebra puzzle. Most students had a chance to take the quiz on our Graphing and Solving Linear Systems using Graphing Quiz on Friday. If you missed Friday, make sure you see me to make up this quiz.
This week we will start working on Solving Linear Systems using Substitution MONDAY LT: Review solving equations using multiple steps (like distribution and combining like terms) SC: Students are successful if they can solve for x when they have to distribute into parenthesis, combine like terms, and then solve a 2 step equation. TUESDAY Notes on LT 4: Solve a linear system of equations by substitution SC: Students are successful if they can solve a system of 2 equations by: - isolating a variable (x) and substituting into a 2nd equation. -solving the 2nd equation for y. -substituting back into the original equation to determine what x is. WEDNESDAY - FRIDAY Practice on LT4: Solve linear system of equations by substitution SC: Students are successful if they can solve a system of 2 equations by: - isolating a variable (x) and substituting into a 2nd equation. -solving the 2nd equation for y. -substituting back into the original equation to determine what x is. |
