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 http://mathforum.org/nsdl_mathtech/sum2006/ We are looking forward to continuing the discussions and viewing the accompanying ratings, comments, and reviews of resources in the Math Tools catalog! ***FEATURED ACTIVITY Activity: Math Insight - Digging Dirt eNLVM (Utah State University) http://mathforum.org/mathtools/activity/25100/ 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. ***FEATURED DISCUSSION Digging Dirt applied problem http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_25100_g-1 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, http://mathinsight.ctl.sri.com/." ***FEATURED DISCUSSION Creative opening question for a lesson http://mathforum.org/mathtools/discuss.html?&do=m&thread=__hsf_lesson__g-1 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." ***FEATURED DISCUSSION Converting units tools http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_3045_g-1 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.) " ***FEATURED DISCUSSION Runners Activity: Some Observations http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_13171_g-16 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...." ***FEATURED DISCUSSION Advantages of interactive Graphs http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_13171_g-9 Aldana offers some questions to consider when presenting an interactive graph. ***FEATURED DISCUSSION Static graph versus Simulation Tool http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_13171_g-5 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." ***FEATURED DISCUSSION Graphing Tool http://mathforum.org/mathtools/discuss.html?&do=m&thread=___disc_13171_g-2 Desi asks, "How can you eliminate students from playing with the tool?"
