Mateo and Ava made a paper cup telephone that they use to communicate with one another. But there is a problem: The string is too long, so there is a lot of distance between the two paper cups. Mateo can hear sounds when Ava speaks, but he cannot hear the exact words. Mateo thinks that they can solve the problem if they develop a code using a pattern of sounds. Generate at least two different ideas that Ava and Mateo could use to communicate with a sound pattern when they use the cups and string. Be sure to explain how each solution would work. *
