Desmos Marbleslides Screencast Hyperdoc

As one of the community coaches for Open Up Resources, we have been shifting our focus from unit overview PLC’s to distance learning PLC’s and compiled some resources. On April 2nd, Morgan Stipe presented on HyperDocs and afterwards I went over the basics of how to use Screencastify [request access to view PLC recording], a screen recording solution. During her presentation, little did I know, that I was going to combine her ideas with mine to create a project for my 8th graders.

That’s what I’m sharing with all of you today. I am proud of it and want you to help me make it better by using it with your students before the school year is over. Personally we have 6 weeks left, and I know New York and other east coast schools started after Labor Day so they have even more time.

Our school jumped into distance learning by doing daily lessons. After spring break, we had some PD days and re-launched with Math and Science coursing having 3 lessons a week, Monday, Wednesday, and Friday. One of those days was expected to be live, and my colleague Bob and I picked Wednesday. By the way, on Tuesdays and Thursdays we do 1 hour of office hours instead of 2 separate 1 hour chunks. Our administration and district is showing grace to myself, students, and parents to not be overwhelmed as they may be otherwise.

Anyways, enough with the logistics. Well, more logistics actually. I posted this morning in my Google Classroom:

Today is a live lesson. I will be explaining a project that will be due Friday May 22nd. For today, wednesday April 29th, here is the schedule for the Google Meet:

9 – 9:45 am 1* and 6*
10 – 10:45 am 4* and 5*
1 – 1:45 pm 3* and anyone who missed their first time slot

Here is the google Meet link. . My expectation is that you are in the Google Meet as well as the Desmos activity which is at this link: . That’s the best way to get live written feedback on Mondays and Fridays also.

Attached is the HyperDoc instruction sheet that I will go over with all the links necessary.

Here is the link to make a copy of the HyperDoc.

I usually wait 3 to 5 minutes after the hour to start and also restrict students to screen 1, which is a starter screen you can add by turning on Desmos labs and making a copy of Desmos Marbleslides to copy and paste this slide into your set. I loved finding out students were learning the guitar, getting to level 35 in Pokemon Go, cooking a lot, etc.


For screen 3 the students had to adjust y=1/2x+1 to have a different y-intercept, so I asked in that what they did to fix it and how they knew it would work, but set my timer for 1 minute for them to type it in the chat box and not enter it until I said so. This is a great tip I learned from Ashli.

what the most important equation of 8th grade was (y=mx+b) and we talked about how m, the number before x was the slope and b was the y-intercept. When you type y=mx+b on that screen it defaults to m=1 and b=1 so I asked students what this new red line had in common with the blue line and they said they both have a y-intercept of 1 but the red line has a slope that’s steeper since 1 is greater than 1/2.

I then restricted their screens to the next few fix it screens for about 3 minutes, paused, asked some questions in the chat, then unpaused for 8 minutes while they examined each part of the equation y=-0.14x+3{x<5} with prediction screens then a verify screen to see if their prediction was correct.

With about 5 minutes left in the 45 minute session, I shared my screen and went to the HyperDocs link to go over the project. The goal is for students to record themselves solving a challenge screen start to finish while explaining what the parts of their equations mean.

Today was easily my best day of distance learning yet. I got to check in with my students. I got to see them engage in math because I went back to my Desmos class code and saw out of 140 students, 79 logged in to the activity. I could see that some students solved more than one of the challenge screens and about 12 students already turned in their screencast according to my Padlet wall. It is a JOY to hear their voice. It's optional to embed the video of your face and I made sure to mention, especially for one particular student (selectively mute), that they could write a written description instead of talking on the video.


One student had trouble installing the extension so on Google Meet I had them share their screen and I walked through the process. Basically it involves signing up at and signing in with Google and enabling and selecting your microphone and webcam. Another aspect I addressed on my screen cast on the HyperDoc

is when you finish recording the screencast you can copy a shareable link to the video because it automatically saves to your Google Drive. They then copy that link to a Padlet wall I created.

Please let me know if you use the activity with your students, I promise you and your class will not regret it! I want to share an example from a student and I am waiting on them to give me permission since it has their name on it.

    1. Awesome please tell them to let me know if they use it. I want to make the instructions more concise and clear and I am open to you and your teams ideas.

      Did you see the example video at the end of the blog post? I can private message you the padlet wall with more examples. Such a joy hearing their voice narrate some math. It’s intimidating.

      I feel I can improve it right now by providing sentence frames.

      “The first equation I’m going to type is… I am going to use a positive/negative slope because …. and the y intercept is going to be… since ….
