DESMOS ACTIVITY CARD SORT HOW TO

Those who are beginners will want to watch the beginning videos on setting up your account! Another mistake was not to realize once you pulled out a GCF it was a different of 2 squares or a perfect square trinomial.Do I need to have a background in Desmos in order to take this course? I went around individually to each student and showed them their answers on my computers and what they did incorrectly. One important one was students were putting a sum of 2 squares under a difference of 2 squares. I love that I can see there progress, comments, thinking, and mistakes (as them fix them live!).ĭesmos Activity 2: Factoring Sort - We did not have enough time to get very far (we could have used an hour period) but it did reveal some misunderstandings. I read their responses and shared the analysis with the class. The original student who did not look at form, originally looked at reflection and this time now looked at form. Some did was it vertically stretched or compressed (still looking at a). Then, it asked them to sort another way - what, a 3rd way? Most did it by the value of a - was it positive or negative, was it reflected over x. It turns out she sorted by how many solutions - 0, 1, or 2 solutions. It finally took them away from just seeing the form. It took the students quite a while to figure out how she sorted. Then, in slide 3, a Desmos student sorted them into three piles. All but one of my students sorted by the form of the equation - vertex and standard. It asked the students to sort quadratic equations. The first one was more powerful than I anticipated. Then, I was going to try 3 Desmos Activites. Question 8: What are you still unsure of from the previous unit. Question 7: This one had mixed results - looking at the reflection: Interestingly, a good amount of kids stayed with the fractional form. Again, an issue with not writing in standard form. Question 6: Write a quad in standard form with x-int at -1/3 and -5. A big problem was form - some wrote in factored form. Question 5: Write a quad in standard form with an x-int at -4. Next class is imaginary numbers and complex solutions. Question 4: When would a quadratic have no solutions - got two possible correct answers and good connection to the graph in understanding this.

Question 3: Write a quadratic tangent to the x-axis - one did not know what they meant (need to clarify vocab), otherwise, pretty good. Question 2: A few divided by zero and threw away an answer. Question 1: They understand the Zero Product Property and how it is used to solve quads by factoring. This was new this year, so it makes sense and we will be revisiting it. The biggest area of unsure students is Inverse. I do have one student who is still unsure of how graphs are transformed and I will definitely reach out to her. I put my thoughts into a powerpoint for the next class's opener (using formative assessment to change teaching). I learned quite a bit from these 8 questions.

I wanted to see where we are and how to move forward (formative assessment). We have recapped Algebra 1 Quad stuff - graphing from all forms and the start of solving.

I first collected information from a Google form as a lesson opener. I dressed up in Desmos and one student told me 'It was like I was sponsored by Desmos.' Proudly! In Accelerated Algebra 2, we are having a Desmos Day with Quadratics.
