I am trying to create an activity to identify my students’ strategies to retrieve addition/multiplication facts. I want to use a timer , since this is an indicator of whether they use counting on to retrieve facts. I would use the data to review in small group efficient (addition strategies)ways to retrieve facts.
My question is: once the time has elapsed.. how could I lock the table to force students to move to the next slide? I have spent countless hours in cl. desmos,com trying to find a solution.
Besides looking, my skills are limited..
!
I want something that looks like this when the timer reaches 0 seconds. Taken from an activity from: [Copy of] Stopping a timer when all questions are correct

Hi @Poovandrie_Jansen , I locked the table cells like this when the timer expired
cellEditable(1,3): Timer.script.timeLeft>0
I needed a separate statement for each row of the table, which is a bit cumbersome.
See Increasingly Difficult Differentiation which is designed to test students fluency with differentiation.
It’s not perfect and if students move off screen 1 after pressing the Start button then the timeSincePress sadly fast forwards to the maximum.
I should find a way to disable the new Done button that has appeared in Desmos recently as I suspect that will also impact running timers.
I’ve heard in the forum that there is a hideNextButton feature that you can add to a screen, but there isn’t any CL documentation for it yet
