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 ...

Big Idea – We can describe, measure, and compare spatial relationships. to build on students' knowledge of triangle and develop students' reasoning with properties of different classes of triangles to ...

We’ve looked at reversal patterns (head and shoulders pattern and inverse head and shoulders pattern). In this lesson, we cover continuation patterns, specifically the symmetrical triangle pattern.
