After exploring further with the graphing capabilities of the TI-84, desmos, and geogebra, I have learned many features I did not know previously. On the TI-84, I learned how to split the screen so it can include a graph and a table simultaneously. This will prove useful when teaching because I can show my data in multiple forms at the same time and not have to switch back and forth. On Desmos, the feature I enjoyed the most that I did not know about before was graphing inequalities. On Desmos you can set multiple inequalities up and color code them to visually show how each would look. On Geogebra, I found out that you can easily find local extrema, zeros, slope etc. using the tools in the program. This will certainly be useful for conveying ideas in a class such as calculus without having to find certain points by hand or a traditional calculator.
I am currently a TA in a 7th grade pre-ap prealgebra class. I hope to one day teach any subject from 6th grade math to geometry when I start teaching full time. Through my time in the classroom, I have observed how technology such as the TI84 and Desmos are used in a variety of different types of lessons. My students today used a table to graph points, drew a line that represented the mean, and calculated the mean average deviation all on Desmos. I could also see this type of technology being used for any lesson centered around algebra or geometry since the graphing layout is so easy to use.
