### Week of February 12, 2018

This week we’ll continue with system of equations. However, substitution will be used instead of graphically. This is also known as solving systems algebraically.

## Monday 2/12:

**Learning Target:** I can find the solution to systems of equations by substitution.

We switched gears by performing systems of equations with substitution. This is a little more entailed and requires knowledge of solving equations accurately.

We viewed this PowerPoint here: Solving Systems by Substitution-1ip4c2t

The following video was shown in class:

This next video might help as well (a little slower paced):

* How will I be assessed*:

Finish “Solving Systems of Equations By Substitution” here: Systems of Equations by Substitution-1nwvir4

**Tuesday 2/13:**

**Learning Target:** I can find the solution to systems of equations by substitution.

Systems by substitution was discussed today with an emphasis of placing one of the equations to slope intercept form. Homework was collected, returned and reviewed quickly. Anyone who did not complete this assignment will have to do the alternative assignment below (see directions).

**How will I be assessed:**

**Math 8:** Choose 10 problems from here: Solving Systems of Equations by Substitution 2-1u3wsok

**Adv M8:** Choose 15 problems from here: Solving Systems of Equations by Substitution 2-1u3wspi

**Alternative Assignment:** Because the assignment due today was not submitted, staple the completed homework which was due today to this completed assignment: Alternative Assignment February 13 Substitution-2mlk9io

**Wednesday 2/14:**

**Learning Target:** I can find the solution to systems of equations by graphing and substitution.

Students were given the opportunity to practice systems. Extra credit was offered today (1 point each).

* How will I be assessed:* Extra Credit here: Graphing & Substitution Systems Extra Credit-1fse7pb

**Thursday 2/15:**

**Learning Target:** I can find the solution to systems of equations by graphing and substitution.

Students practiced the material by choosing problems from the quiz to do over again. All questions were cut individually and placed in front of the classroom. Students could choose which questions they wanted to do again. Both quizzes and Unit 6 tests were fully reviewed in class today. A quiz tomorrow on substitution and graphing as well as a grade recovery opportunity for Unit 6 will be given tomorrow.

* How will I be assessed:* Students had the option to work on page 707 (1-6) and page 713 (1-8). This is practice, not homework.

**Answers:**

**Page 707**: 1.) (4, 4) 2.) (2, 4) 3.) no solution 4.) infinite solutions 5.) (0, 3) 6.) (4, 2)
