I am an elementary school math intervention teacher and I love Desmos.com! Desmos is geared toward middle, high school, and even college math teachers and students but you can also create games and activities using your own images for your elementary age students. I created this Colors and Shapes game for my students and I thought other people would like to try it as well.
This is a free download with the Desmos code to play this particular game. You and another player must be signed in with the same game code to play the game.
This particular game is similar to the Guess Who? game where you ask your partner questions that elicit a yes or no answer. For example, Is it red? Students can type their questions or use the microphone feature on iPads to ask their questions. This has been wonderful for my second language learners.
I hope I inspire you to create your own games on Desmos and make them public so others can enjoy them!
