•PowerPoint presentation lesson: 16 slides
This lesson covers solving linear equations in one variable that have no solution or infinitely many solutions. The presentation includes a pre-requisite knowledge warm-up, a description of how to identify how many solutions an equation will have, and 9 examples of solving equations. The examples include equations that have no solution or infinitely many solutions, as well as equations whose solutions are x = 0 or x = 1 because it can be confusing for some students to distinguish between these types of equations and those who actually have no solution or infinitely many solutions.
• Filled-in PowerPoint presentation: 16 slides
This version of the PowerPoint lesson includes the work, answers, and explanations that the students would have heard and seen during the lesson. This is a great resource to provide to students who were absent on the day of the lesson and to students who need accommodations or modifications.
• Guided notes: 2 pages
This PDF document directly follows the PowerPoint notes for this lesson. These are great for students who need accommodations or modifications. Or, provide these for all students to increase the speed of the lesson and to allow students to spend less time copying and more time participating in the lesson.
A printable version of the warm-up from the notes is also included, including an answer key. There are four warm-ups per page.
• Exit Ticket
A short, two-question “exit ticket,” is included, and the answer key is provided. These questions mirror the types of questions that students saw in the notes and can be an efficient way to gauge how well students understood the lesson. Additionally, the back side of the exit ticket asks students to rank how they feel about the concepts taught from 1-4. There are four exit tickets per page.
• “How Many Solutions?” Sorting Activity
A fun way for students to practice the concept taught in the lesson. This activity includes two worksheets and 15 problems on slips of paper. The first worksheet is for your students to show their work on. The second worksheet is for them to paste the slips of paper on according to how many solutions the equation has. An answer key is provided. (Note: You or your students will need to cut the 15 slips of paper out before using this activity.)
• Worksheet: 11 problems
The first two questions on this worksheet ask students to explain what it means for an equation to have no solution or infinitely many solutions. The following 9 problems are examples of equations that have no solution or infinitely many solutions, as well as a few equations whose solutions are either x = 0 or x =1. An answer key is provided.
• Quiz: 4 problems
This half-sheet quiz asks students to solve the same types of problems they practiced in the notes and on the worksheet. This type of quiz is great for quick, formative feedback between teacher and student. An answer key is provided. Also included are two other versions of the same quiz that can be handed back to the student with their graded quiz. The first asks students to describe what mistakes they made on their first attempt on the quiz. The second asks students to provide the correct work for each problem they made a mistake on.
