Big Idea:This lesson gives students a hands on approach to learning about systems of equations with something that they can all relate to...money! By placing constraints on the value of coins and the number of coins students see that there is only one way to meet
Big Idea:This lesson serves as the link between understanding constraint equations algebraically and understanding them graphically. Students will investiagte the appearance of systems of equations in the coordinate plane.
Big Idea:This lesson is all about making connections between the solution to a system that students see graphically and what that solution means in terms of each equation. Students will have an opportunity to practice graphing systems of equations and showing what
Big Idea:This lesson is great because it allows student to design equations based on given information but most importantly it allows them to analyze the finished graph. Students are able to build and pull meaning from their work and use the mathematics to help th
Big Idea:Students love to send text messages and some have to pay for their own cell phones. This lesson turns the tables and puts the students in the position of pitching cell phone plans to consumers. They use their knowledge of systems of equations to make gra
Big Idea:Every equation is really a system of equations! Students don't usually see it that way but this lesson will help them to make that connection. Students will practice writing simple linear equations as a system of two functions and finding the solution bo
Big Idea:I really like this lesson because of the scaffolds that are in place in the beginning of the lesson. The examples are very simple but really force students to think about what it means to "substitute" one thing for another. Then, once the problem becomes
Big Idea:Students need an opportunity to practice mathematical skills and procedures with examples that are challenging but still at their level. That is what this lesson provides. By the end of this lesson students should have fluency with solving system of equa
Big Idea:This lesson is great on a variety of levels. First, students are solving a real-life problem that requires them to grapple with "unfriendly" numbers. Second, students are challenged to think about accuracy in measurement through the lens of systems of eq
Big Idea:This lesson serves as a closure to linear systems. Students will make connections between solving a system graphically and by both algebraic methods (elimination and substitution). The system of equations is used to model a real world situation.
Big Idea:I love surprises in mathematics. When you expect something to go one way and it turns out differently that leads to real learning. Students are usually shocked by the speed at which an exponential function grows in relation to a linear function and this
