Unlucky Zeros
fractions · reciprocals and multiplicative inverses
Demonstrate concretely, pictorially and symbolically that the product of reciprocals is equal to 1 [8.N(NC).3].
Unlucky Zeros is a Grade 7 fraction game focused on reciprocals and multiplicative inverses. Players roll a die and place the value into blank spaces only when it helps create a true equation. Rolling zero is dangerous: each zero removes one of three stars, and a player drops out after losing the third star.
Use it for small-group review when students are learning that a number multiplied by its reciprocal equals 1. The option to leave a roll unused encourages students to reason about whether a value can complete a valid reciprocal relationship before placing it.
