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
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
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....

***FEATURED DISCUSSION
Converting units tools
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
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
Aldana offers some questions to consider when presenting an
interactive graph.

***FEATURED DISCUSSION
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."

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