A list of Desmos activities created over the last few years. Some of them were created before screen gates (and I've been too lazy to edit them) so they are in two pieces.

Introduces Students to the concept of square roots and their approximations.
Can your business make money? Control product, cost and advertising to maximize profit
How much is the cover charge? You and a friend visit the arcade and spend various amounts of money. Use the number of games played and the amount of money spent to figure out the cover charge.
How many shirts do you need to sell in order to make a profit? Classic cost vs. revenue problem with a twist... how much should you charge for your shirts?
Figure out the missing number using a string of clues. Introduction to solving two step equations.
Without any measurements can you estimate the value of different fractions?
Type your name and it appears in a graph... trace your name on the next screen and hide the letters to see your art! extensions into binary and other operations coming soon.
Look at and make observations on various linear situations.
Similar to Desmos put the point on the line. Understand slope and rise/run.
race to the finish by completing integer operations!
Original idea here:
challenge your partner!
Watch out for inappropriate responses
Use patterns to take a deeper look into linear relationships
How much would you spend at a carnival?
How far would the space ship travel after 10 years?
manipulate m or b to make the line pass through the gap safely
move the functions so that they pass through the gaps correctly
Go through a series of questions relating to integer operations. Numbers in questions are randomized to avoid copying
A first look into linear functions and proportional relationships
Help students recognize the 8 standards for mathematical practice in everyday tasks
Convert between mixed and irrational numbers by "finding the magic number"
Discover the golden ratio with your fingers and a few sliders.
Take a look at satellite dishes and parabolas
Begins with a review of prisms and right triangle trigonometry. Takes a more in-depth look at pyramids and cones.
Takes a look at angles who's vertices are inside the circle
