Through engaging activities and discussions, students will develop a strengthened mathematical belonging by connecting with the rich heritage of Africa, fostering a sense of pride and recognition in their own black identity.

### Persevering Through Problem Solving with Open Middle: Order of Operations

In this lesson, students will engage in a low-floor, high-ceiling Open Middle task that challenges students to think critically about order of operations. Suggestions for facilitating this lesson based on Building Thinking Classrooms are provided, as well as extension questions and questions for reflection.

### Patterns and Functions

Pre-K-2
In this lesson, students will explain their understanding of patterns using their home languages.

### Pythagorean Theorem with Technology

In this lesson, students will extend the Pythagorean theorem by investigating the relationship between the areas generated by the lengths of the sides of a right triangle, investigate whether the Pythagorean theorem still holds if the shapes are not squares, and investigate whether the Pythagorean theorem still holds if the shapes are not regular.
