Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links ...

Translations and reflections are examples of transformations of shapes. If a shape is transformed, its position and/or size is changed. Translation is when a shape slides across, up, down or ...

Mathematician Katie Steckles explains just why the proliferation of snowflake decorations this time of year is deeply annoying ...

Teacher educators guide student reflection by transforming specific microteaching moments into “reflect-ables,” using gestures, notes, and interactive discussion to co-construct professional learning ...
