BINDER ORGANIZED! You should now be able to locate Binder material when you need it. Future PD sessions are being planned, and we will continue to add to the binder!
Now on to Goal 2: Brainstorm/Discuss Math Strategies for use with the INS course
Math Skills and INS Number Sense –Measuring, creating graph scales, recording data Basic Math Operations –Which number goes in the calculator first? –Percent Error Solving 3-variable math equations –What to do with pre-algebra students? Interpreting and solving word problems –How to set a routine approach?
Learning Strategies vs. Practice There are numerous skill sheets for students to use when practicing math skills Usually, practice alone is not the answer. One must FIRST teach a strategy for success, and THEN give students practice.
Group discussion: What are some of the things students struggle with when collecting, recording, and interpreting data? Discuss this in your group and try to identify one or two top issues What strategies can we use to help students become better data collectors, recorders, interpreters? What difficulties do students face when working with data?
Group discussion: What are some of the things students struggle with when calculating speed or force? Discuss this in your group and try to identify one or two top issues What strategies can we use to help students calculate quantities and rates? What difficulties do students face when performing calculations?
Strategy For Substituting and Solving Magic Triangle
Problem Solving Routine I Identify unknown rate or quantity L List known rates and quantities A Arrange all into a formula S Substitute and Solve H Highlight number answer with unit
Helpful skill builders Skill builders found at the end of the CPO INS skill and practice Worksheet booklet (on CD ROM) Calculating Slope Dimensional Analysis Fractions Review SI Measurement Problem Solving with Rates Significant Digits Working with Quantities and Rates Scientific Notation
Extra Practice Skill Sheets found in your 3 ring binder from training session Solving Equations Percent Error Significant Differences in Measurement Scientific Notation
Good News With the CPO INS program, students are constantly recording data and working with measured quantities and rates. The more practice they have, the more routine this becomes!
Types of Graphs: BAR GRAPH Use for “chunking” or grouping data Show trends Does NOT allow cause and effect comparisons
Use for displaying percentages Does NOT allow cause and effect comparisons Types of Graphs: CIRCLE OR PIE GRAPH
Similar to Bar Graph; used to show trends Does NOT allow cause and effect comparisons Types of Graphs: LINE GRAPH Type 1
Used most often in CPO INS Independent/D ependent Variable Comparison (Cause and Effect) LINE GRAPH Type 2 (scatter plot)
Group discussion: What are some of the things students struggle with when creating a graph? Discuss this in your group and try to identify one or two top issues What strategies can we use to help students with their graphing skills? What difficulties do students face when graphing?
Graphing Routine MMaximize graph area IIndependent variable on… XX axis T Title U Units with labels SScale with evenly spaced increments CContinuous Smooth Curve
Memory Aids X is across, Y is up high Independent = manipulated (cause) Dependent = responding (effect) When time is a variable, it always appears on the X axis (Time is the ultimate independent variable; time waits for no one!)
Creating a Scale Start the scale and have students fill in missing numbers Decimal problems? Drop decimal, make scale, and put decimal back in Deciding the value for each box on the graph is no easy task! Once students create a scale, can they use it when plotting data pairs?
Begin Session 2: Chapter 5 investigation with the Roller Coaster
Key Questions What happens to the motion of a marble on a hilly track? How is energy conserved on a roller coaster?
Roller Coasters Millennium Force at Cedar Point: 300 ft drop 80 degree angle of descent 93 mph $25 million to build Fastest coaster: Japan, 106.9 mph Biggest wooden coaster drop: Paramount’s King Island, 214 ft drop
Investigate Motion of Marble How long does it take the marble to break the photogate beam at each of the 7 positions? Do smaller times correspond to faster or slower speeds?
Investigate Motion of Marble How would you calculate the speed?
At what two positions is the marble moving the fastest? What is unique about these two positions?
Investigate the relationship between speed and height more closely Find the speed of the marble for each of 12 different positions on the coaster Use the table provided to record your data (note: you don’t have to measure height of marble) We will graph the data after lunch
Take a look at alternative labs Today’s handouts included optional chapter 5 investigations for beginners and advanced students. Will you use any of these optional labs?
Compare steel and plastic marble speeds Will the plastic marble have a speed that is greater than the steel marble, less than the steel marble, or the same as the steel marble? Design an experiment and find the answer! Can you explain the result?
