Types of Lines While parallel and perpendicular lines will be the primary focus of this chapter, there are other types of lines. Use the Types of Lines Foldable to distinguish between them. Types of Angles When two lines are cut by a transversal, there are special names for the angles formed by the transversal and the lines. [...]
When businesses, governments and other policy makers prepare to make decisions, they often look at data to find trends. In this activity, we will use data and a graphing calculator, Desmos, or Geogebra to find an equation that best fits the data points. Statista has Global Apple iPod sales (in million units). Plot the data [...]
Go to Geogebra.org. Click on Geogebra Math Apps. Choose Spreadsheet. Enter your data in the spreadsheet. Click in the graph area, then right click and choose Graphics. In the Basic tab, change your x- and y- mins and maxes to represent your data points. Click on the Grid tab and Show Grid if you want. [...]
Go to Desmos.com and choose Start Graphing. In the upper left, choose Add Item > table. Type your data in the table. Click on the wrench in the upper right to change the graph settings. Modify your x, and y values to reflect your data. Decide what type of equation the data represents. In the example [...]
Calculator Set Up Make sure that your calculator has the Plots Off, Y= functions cleared, the MODE and FORMAT are set at “stage left”, and the lists are cleared. Turn the Diagnostics on. Press 2nd the CATALOG (2nd of 0). Press the teal D button (ALPHA of x-1) This brings you to the items in [...]
Conditional Statements My goal for this unit is to help students see the goal of becoming more logical, methodical, and developing their pre-frontal cortex. After the chapter 1 test, I gave them a copy of Who Owns the Zebra? While a few flew through it, some didn't know where to begin. If I have time, [...]
Reviewing Parent Functions In Pre-Calculus class we dove right in and reviewed five of our parent functions. Screen shots of Reviewing Parent Functions Geogebra Activity are shown below. I will likely rework it next year to include a slider for a variable "b" that reflects across the y-axis and horizontally stretches/shrinks the graph. I made [...]
Polynomial Functions Pre-Calculus has a heavy emphasis on learning how to graph various functions. The Polynomial Functions Exploration is one strategy for learning how various functions behave based on the sign of their leading coefficient and the highest power of the polynomial. I find that my students remember functions ending behavior better when they discover [...]
One frustration I encountered last year in my geometry classes involved the Distance and Midpoint formulas. Our text book and I made the assumption that since my students had worked with these formulas, they would remember them and could use them. We encountered problems throughout the book that required the use of both formulas and I [...]
