Periods 2 and 3
As a way to summarize the concepts we learned in "Mathematical Models," students worked independently or with one partner to create a technology project on linear and inverse relationships. Students used ComicLife, Pages, Prezi, or Keynote to present their ideas.
Period 2 began this today and will work on it again tomorrow.
Period 3 began this on Friday and had the entire time in class today to work on it. For Period 3, this is due tomorrow.
Assignment: Period 2—work on project (due on Wednesday.)
Period 3—complete project (due tomorrow.)
Continuing our work with exponents we began talking about exponential growth. In these cases the independent variable, or x, is an exponent. Because of that the resulting graph is not a straight line, but a curve.
We discussed how to use a table to write the equation and to graph the resulting equation.
We will continue work with this tomorrow.
Assignment: p. 524, #1 - 2, 4 -8.
Continuing our work with quadratic equations in the form ax² + bx + c, we discussed what to do if there is a negative coefficient of the first term—you factor out a negative 1. We also discussed common factors and how this simplifies solving equations. We started to talk about the vertical motion model and will expand on that tomorrow.
Assignment: p. 597, #1 -3, 12 -21, 23-26
