Desmos Art Functions Card 2023
https://www.desmos.com/calculator/2gkamtbsoc
- I figured out which equations to use by look at the shapes and deciding what I need to use. I had all the different basic functions out so I could look at them and decide which one I needed to choose.
- When something didn’t work out, I had to play around with it, and trial and error sometimes. It cost me a lot of time when things didn’t work out and when I was trying to get a hang of things.
- I had an aha moment when I figured out why an equation wasn’t working, and I realized the r squared was negative and so I changed it to a positive and it worked.
- I didn’t get any help on this project. I pushed through it all by myself.
- A strategy I used to make sure things were more efficient was to use one type of function/equation that my project needed until I no longer needed it anymore, and then move on to another type of equation/function.
- This assignment helped me understand more about transformations of functions and relations as I had to do things repeatedly and visually see what changed what, and what part was doing what to the graph.
SELF REFLECTION BELOW:
| Mark | EDUBLOG POST: Process (5 marks) | Score |
| 5 | I clearly described my process, strategies and how I resolved any difficulties I encountered. I correctly Tagged and Categorized my post. I inserted a picture of my desmos post card and the original picture. The link to my edublog is pasted at the bottom of this self-assessment. | |
| 1 | My explanation lacks detail and/or I have not described my problem solving process. The link, desmos picture and/or original picture are missing. | |
| 0 | I did not complete the Edublog post. | |
| Folders (5 marks) | ||
| 5 | My folders are labelled with parts/objects,/letters and I correctly identified EVERY type of function and relation used. | |
| 2 | My folders are labelled with body parts and types of functions used. Some functions are not identified or incorrectly identified. | |
| 0 | I did not use folders. | |
| Image (10 marks) | ||
| 10 | My drawing resembles the photo I chose | |
| 5 | My drawing is starting to look like the photo chosen | |
| 1 | My drawing is missing or incomplete | |
| Aesthetics (10 marks) | ||
| 10 | Color and shading was used to strategically replicate the picture. | |
| 5 | A little shading was used. | |
| 1 | No thought was put into the use of color or shading | |
| Functions & Relations (10 marks) | ||
| 10 | I used all 10 types of function/Relations required. Absolute Value, Polynomial (Linear), Rational, Radical, Trigonometric, Exponential and Logarithmic, Sideways Parabolas, Semicircles, Ellipses. | |
| 4 | I used only x of the required types | |
| Function notation (30 marks) | ||
| 30 | I made excellent use of function notation to transform the same function repeatedly | |
| 10 | I used function notation a few times in order to transform the same function repeatedly. | |
| 0 | I wrote new equations every single time and did not use function notation. | |
| Creativity and Complexity of Functions & Relations (30 marks) | ||
| 30 | My equations show complexity and creativity. I used multiple transformations. (Stretches, Reflections, Translations, Inverses). I made excellent use of domain and/or range restrictions. I combined functions from different units. | |
| 15 | I used mostly the same type of functions, with some transformations. My functions sometimes overlap because I could not figure out the correct domain and/or range. | |
| 10 | My equations lack complexity and creativity. | |
| 65 | Total mark:
(100) |
