The second activity: Polygraph 1 |
During this activity, we were told to predict whether or not the guy in the picture will make his shot into the hoop. While doing this I took to time to make sure that my predictions were accurate. You were able to later check your answers and see if you were correct or not. This activity was pretty easy, but I did end up getting one answer wrong. This was a good first try at learning about parabolas but it only got harder from here.

This second activity we did was called "Guess my parabola" where we played with a partner online. One partner would pick a parabola for the other person. That other person would ask questions to their partner to help identify the parabola that they chose. This activity helped us a lot with our vocabulary because we got to practice using terms like concave up/down or words like vertex and origin.

The fourth activity: Going through the given points |
Our third activity helped us work on the vocabulary we used in the last activity and also let us practice sketching parabolas. The picture on the left is an example of how I showed "Concave Up" on a sketched parabola. This was pretty simple but got harder as the problems went on.

The fifth activity: Marbles |
In this activity we had to create parabolas that would go through certain given points. In the example (left) the shape of the parabola was basically the same it is just the placement on the graph that was different. The main thing that was changing in the formula was the value that made the parabolas move left/right or up/down.

This last activity on desmos was like a game. We were given a few stars and a marble and we had to create a parabola that would help the marble go through all the stars. First, it started off easy, they gave us a formula and we just had to tweak a few numbers that would help us out. Later, we created our own formulas which made it a bit more challenging for me but I eventually got it right.
Lesson Evaluation: In my opinion, DESMOS did not feel like homework or classwork, but it included challenges that led to our understanding of the topic which is a very good thing. I hope we can continue to learn through challenges and puzzles instead of worksheets and lectures. Self-Assessment: I would give myself an A on this activity because of my ability to complete the challenges and gain a better understanding of the topic. My goals for the semester were challenging myself and helping my classmates and I fulfilled these tasks. I helped my table understand some of the changes you had to make with the variables which at the same time gave me a better understanding. |
