         MATH TOOLS NEWSLETTER - JULY 1, 2006 - No. 41

  Thank you to everyone who participated in our discussions
  as we hosted simultaneous workshops in Houston, TX, and
  Philadelphia, PA, June 26-29.

  View a record of our workshop's activities here:

         Using Math Software Tools in the Classroom
          A teacher-leadership development program

  We are looking forward to continuing the discussions and
  viewing the accompanying ratings, comments, and reviews of
  resources in the Math Tools catalog!

  Activity: Math Insight - Digging Dirt
  eNLVM (Utah State University)
  An application problem that asks students to help an
  excavation company prepare a bid for one of their clients
  by calculating what they should charge to dig a hole. To
  solve the problem, students must find the volume of an
  irregular shaped prism, convert units, calculate the cost
  based on a linear formula, and write an explanation of
  their calculations. Video clips, interactive tools, and
  guides are provided to help students learn about and solve
  the problem. Materials are based on a scenario and materials
  created by SRI International for the Math Insight project.

  Digging Dirt applied problem
  jd announces, "Digging Dirt is the first of a number of
  applied problems that the eNLVM project will be publishing
  based on materials created by SRI International for a
  CD-ROM product called Math Insight,"

  Creative opening question for a lesson
  vms writes, "I have a task to write a creative lesson opener
  question for some lessons on the topics which don't seem to
  have much relevance to any Real Life or practical application....
  Any advise is appreciated."

  Converting units tools
  denisef asks, "I reviewed our sixth grade benchmarks and
  saw that our students were weak in converting units. The
  examples on the tool at this site are too difficult. Could
  you prepare activities in which students only convert standard
  to standard measures (example, yards to feet, inches to yards)
  or metric to metric (centimeters to meters, etc.) "

  Runners Activity: Some Observations
  Chris T. lists, "A few things I noticed and thought were
  interesting: 1. Position is used instead of distance. 2.
  There are no units for either time or position...."

  Advantages of interactive Graphs
  Aldana offers some questions to consider when presenting an
  interactive graph.

  Static graph versus Simulation Tool
  Mylla states, "The static graph is a good place to start
  the activity and analyze the data. The simulation tool would
  increase student interest, and give them immediate feedback of
  their ideas when presented with various situations."

  Graphing Tool
  Desi asks, "How can you eliminate students from playing
  with the tool?"
