The student will interact with a line segment and will report various conditions on a handout. Positive, negative slope, distance, and midpoints will dynamically calculate as the student drags either endpoint around.

Students will need to have instruction with all formulas, and calculating by hand from ordered pairs. Knowledge of positive and negative slope is important. Radicals that produce exact answers, and reduced fractions are not provided by TI-Nspire technology.

A student handout is provided along with the alg_slopemidptdist.tns file. Student screenshots are also provided on slopemidpt_screenshots.doc.

Assessment and evaluation Formative assessment is provided to the teacher when the student document is complete. Remediation can be provided before a Summative assessment is given. Students can demonstrate how they solved the problems and discuss their work when displayed via a document camera. Activity extensions
