Functions: Defining, Understanding, Graphing and Using Function Notation
During my Functions lesson, I'd like to challenge my implementation of outside sources into the classroom, specifically with technology usage and also have a project based learning activity. I'd like to reacquaint myself with all the different modes, buttons and additional uses of the TI calculators.

Goal for this Lesson:
In addition to presenting students with different types of functions and how graph them, in this unit I'd like to incorporate more technology use. I'd like to include in class calculator tutorials and provide additional supplementary tutorials on how to graph a function (including how to limit it's domain and range on the calculator). Additionally, I'd like to search through the internet for a computer graphing tool that could lead students into a functions project. I found this resource and I'd show my students this resources as an application example for functions. This will allow them to connect how computer programs use functions to create images that they'd typically see in cartoons or animations.
Also, I found a similar project online where students are prompted to create images using different functions. This will be a simpler for them and therefore, more realistically achievable with a smaller time frame. Below are the table and graphed final product that allow students to create awesome images from functions. ( I personally wouldn't encourage such a complex shape for middle schoolers but for the high achiever students this would be suggested, maybe in an honors class.)
Reflection: In order for students to successfully complete this project, students should be taught all the different functions available to use. They also need to learn how the domain relates to the range, and how to write the notation given the image they'd like to create. Additionally, they need to learn what DOES NOT make a function, this will limit the more adventurous images that student may create.

Eleanor,
ReplyDeleteI love your use of technology to teach functions. I am currently in a middle school field placement so I feel that I do not get many opportunities to see technology that is exclusively useful for high school math students. I thought that the website you linked that demonstrated graphing and a calculator for students is a great way to model problems for students as the teacher. I definitely will be putting those resources in my toolkit!
I love desmos, because it gives kids more control over how the functions look, and give students the opportunity to play around with functions more, compared to a graphing calculator or wolfram alpha. I also really enjoy the activity of plotting points to create an image, and while I agree that such a complex shape might be a deterrent, I would go for it anyways, and have students who might excel more in math help out students who are having a hard time understanding how to graph specific curves.
ReplyDeleteGreat peer feedback.
