You’re probably here because you were looking for creative ways to engage your child that is a fun, visual, and thought-provoking experience. A "Which One Doesn't Belong" routine encourages students to reason about the similarities and differences among a set of numbers, expressions, shapes, or images. This class is not your ordinary “Which One Doesn’t Belong?” class. Kids examine every portion of each object on a page. They are expected to “think outside the box.” 

Using Which One Doesn’t Belong? (WODB) activities are a great way to instantly spark creative and critical student thinking that will last for the entire lesson. WODB activities help your kids to develop reasoning skills, make logical arguments, express their ideas in words, and engage with visual mathematics—which ultimately leads to a deeper and more meaningful understanding of challenging topics and concepts.

 WODB activities do not have a single correct answer - only a reason why the student chose it.
