Performance Indicator - MST3.5.R.3:
Students read, interpret, and extend external models.

Performance Indicator - MST3.5.R.4:
Students use standard and nonstandard representations with accuracy and detail.

Performance Indicator - MST3.5.R.5:
Students use representations to explore problem situations.

Performance Indicator - MST3.5.R.6:
