Lucky Duck (Expected Value)
Carnival games are games of chance or skill played at events such as fairs and festivals. Some are considered to be rigged because the odds of winning a prize are very low. Sometimes, local authorities test the games to ensure they are fair.
In the Lucky Duck Gizmo, students help Arnie the Carnie design his game of chance. In the game, rubber ducks floating in a pond are selected by a contestant. Students can determine how many ducks win prizes and the value of each prize. Can they help Arnie make money or at least break even? Can they design a “fair” game?
Designing, playing, and analyzing the Lucky Duck game provides a fun way for students to learn about probabilities and expected values. Other Gizmos that help students learn about probability are Spin the Big Wheel!, Theoretical and Experimental Probability, and Probability Simulations.

Everybody's Talking About Gizmos
Hello, Ms. D. I apologize about emailing you during the weekend, but I couldn’t wait to tell you. Gizmos is so much fun, and I absolutely love it. I actually learn something and I like the fact that it is interactive. Thank you so much for making us do Gizmos.
- Gizmos Student, American International School, Abu DhabiI really love Gizmos as they help students grasp difficult concepts that can’t always be seen. They make abstract ideas come to life.
- Gizmos Teacher, Foothills School Division, Alberta, CanadaI’m really a strong proponent of Gizmos in science because I have seen firsthand what it does in terms of engaging kids in labs. Gizmos really allow students to go deeper in terms of problem solving and critical thinking.
- Gizmos Assistant Superintendent, Miami-Dade Public Schools, FLGizmos STEM Cases improve students’ content knowledge and critical thinking ability. The kids are putting more thought into things and they’re asking better questions.
- Gizmos Director of Science, Gwinnett County Public Schools, GAGizmos STEM Cases is the most engaging program that I’ve ever seen! High-quality graphics and real-world stories make them more thought-provoking than traditional teaching materials. Students become more personally invested in the lessons and feel a sense of accomplishment [when doing them].
- Gizmos Director of Science, Walker School, GAGizmos have earned every major edtech award!
