Graphing+Equations

** Graphing Equations **

Teacher Candidate: Jennifer Brumbaugh, Rudy Joya, Patton Richard, Tyson Sturza Date and Time: March 3, 2010 and 10:00 am Grade Level and subject: 9th grade and algebra

Learning Targets:
Students will be able to define slope, the parts of an equation and uses of slope. Students will be able to use a calculator to graph a given equation Students will be able to match what the graph is showing with an equation Students will be able to explain how to graph an equation on a graphing calculator.

Assessment Strategies: At the beginning of lesson students will be define words from previous lessons. After the lesson students will have to complete a sheet that with different graphs and equations using the graph calculator as a check of estimated guess on graphs.

Grouping of students for instruction: Students will be handed a playing card when they enter the classroom. This card will match one already on a table and that will become students new table group for the day.

Instructional Materials, Equipment, and Technology Needed: Worksheet at the beginning of the lesson review prior lessons and knowledge Worksheet with different graphs and equations Graphing calculators for the class A calculator overhead viewer

Prior knowledge and skills: Students will need to have worked with slope before and understand already how to graph the equations and figure out equations from different information. For example if students were given m and b they would be able to come up with an equation and then graph that equation.

Learning Experiences: Students are given the opportunity to learn how to graph a given equation, but also to explore how a calculator can be useful as problems become more difficult.

Lesson Experiences: Anticipatory set Passing out of cards: we want to change up the groups. So we are handing out playing cards to change the groups as people walk into the classroom. The tables will be labeled according to the cards being used.

The lesson The beginning of the lesson will be having students go over the worksheet with definitions and a few short problems. This worksheet is done individually and then talking about it as a group. Teachers will be going around to see if there is one-question groups are stumped on. The worksheet is review everything that has been done in the past lessons.

Next we will go into how to work a calculator to solve the last problem on the worksheet. Students will then be handed a worksheet that goes step by step as to how to work with calculators. We will then run through how to use your calculator to graph equations and use the calculator to check your answers.

Students will then be given a worksheet that has a bunch of different types of equations that need to be graphed. There is a mix of sin, absolute values, and fractions. The purpose of this worksheet is to have students work with their calculator and figure out how to graph complex calculations.

Ending of lesson We will wrap up the lesson by explaining how a calculator can be used in complex situations and in real-life situations involving slope.

Explanation
This lesson is a great use of calculators. It allows students to first use prior knowledge as to what a graph looks like. Then it goes into how to use a calculator for graphing equations. Finally ending with students doing multiple graphs and equations. This lesson explores the advancement of difficult equations.
