Velocity Day 7

Opener 10/13/15  Chunk the second half of your “Slope and Equations” notes  Main ideas: linear equations, the velocity equation, application of the equation  For each chunk, write a question that can be answered using your notes  You have TEN MINUTES

Agenda  What is the assessment about?  How to “manipulate equations”  Practice Problems  Complete  Posterize  Challenge Problem: Marble and Ramp Lab  Check for Understanding

Assessment Next Monday  On the assessment, you will need to be able to do these things:  Make a graph, using a set of data  Find the slope of the line  Write an equation in d=vt form  Use the data, the graph and the equation to:  Answer questions  Make predictions

Learning Targets  I can model the velocity of an object using tables, graphs and equations  I can manipulate an equation to solve for a variable  I can use an equation to calculate the velocity of an object

Handout  Turn to next two blank facing pages  On the right hand page glue in the “How to Manipulate Equations” handout  You have two minutes

How to manipulate equations  What does “manipulate” mean?  To move, arrange and control  Manipulate equations=move the parts of an equation around  In math: “solve for a variable”  Why do you do it?  To get the equation in a form that matches the question you are trying to answer  How is it done?  Follow along and complete the handout...

Quick Practice 10 minutes  d=vt  Solve for t  95=9.5t  Solve for t  100=5t+10  Solve for t  d=4.6t+15  Solve for t Solve problems on left hand page, facing handout Title Page: “Practice” I will call on students to solve problems under the document camera

Practice Problems, Part 1  Solve the practice problems that you wrote!  Ziady added one...  Ziady will model the problem solving steps on the first problem  You have 20 minutes!  If you finish early, write a SUMMARY for your notes

Practice Problems, Part 3  Make a poster  Top of poster: write the problem  Divide poster into two columns:  Left side: show ALL the steps you took to solve the problem  Right side: write a sentence that describes what you did and explains why you did it.  You have the rest of the period

Marble on Ramp Lab Challenge Question
