We did one more Desmos Activity in class today to practice our identification and communication of a parabola’s key features. On Monday, we will have a homework quiz about Wednesday’s HW 3.3 and today’s HW 3.5.
Today we took some time to review the vocabulary we introduced yesterday. Your homework is on IXL, and is as follows:
Use your graphing calculator or Desmos.com/calculator to make graphs. If you exceed the minimum requirements of this assignment, your work will be recorded as extra credit.

Today was Day 3 of the Desmos-based activities we’ve been using in class to re-introduce ourselves to parabolas. In class yesterday, many of you had some difficulty in properly describing parabolas or in identifying features of parabolas to ask about in order to guess which one your partner had chosen. This shows us that there is a need for a shared vocabulary when describing these entities. Today’s lesson reviewed that vocabulary.
We continued our re-introduction to Parabolas and Quadratic Equations today by playing a game similar to the classic game Guess Who, where you had to ask a series of questions to guess which of 25 parabolas your randomly matched partner selected. This taught us the value of having clearly defined vocabulary to describe the key features of such shapes, as several questions that you asked each other led to confusion!
For tonight’s homework, please complete the Parabola Polygraph Debrief reflection. You will also need to bring in your Chromebook once more tomorrow for the third and final introductory activity to this unit.
Today in class, we did a (hopefully fun!) activity introducing our next unit on Parabolas and Quadratic Equations. Your homework tonight is to reflect on two questions:
- Describe one thing that you learned from the Will It Hit the Hoop Desmos activity from class.
- What else do you think you could use a parabola to model the shape/path of?
Write your reflection on a piece of paper or record them in Socrative (room code G102KIRK)
Bring your Chromebook in tomorrow again for Part 2 of this introduction!
