I don’t want the students to have access to a calculator to estimate square roots.
If you are talking about the scientific calculator I believe it is hidden by default in activities (https://twitter.com/Desmos/status/1242306522027155457).
As far as the keypad goes I don’t think that can be disabled. Even if it was disabled, students could still use the square root symbol by typing sqrt.
However, you can prevent boxes in your activity from evaluating (aka prevent 2+2 from showing up as 4). You can do this in CL by using disableEvaluation:true
Thanks for your quick response. Have a great day.
