Understanding
Students develop an understanding of the properties of operations and how to use them to create different but equivalent expressions .
What to look for
This activity can be used to serve two different levels of learning. First to develop flexibility using negative number in simple linear expressions, and second to prepare students for factoring or expanding polynomials. Care should be taken not to overreach with the first level.
Sample Assessment
Find the value of \(p\) so that the expression \(\frac{5}{6} - \frac{1}{3^n}\) is equivalent to \(p(5-2n)\).Answer: \(\frac{1}{6}\)
