2.+Soup+and+Salad

=SOUP AND SALAD: The VITAE Framework = rather than hands-on dragging with sketch.
 * __V__isualize** - A problem is posed. Initial conjectures are based on mental visualization

**__I__nstrumentalize** - Measurement instruments are used to further investigate conjectures. Revisions are made based on new findings.

**__T__race** - An ordered pair is constructed from two geometric measures. A trace of the ordered pair is generated by dragging to foster further revision.

**__A__lgebratize** - Students build an algebraic model for the traced curve using knowledge of underlying mathematics in sketch.

**__E__xtend** - (Optional) Students construct a fit model using statistical routines / regression to check work; Students and Teacher extend the original task using the What-If-Not (WIN) protocol (Brown & Walter, 1990).
