Inside Mathematics
Hexagons
Scholars find a pattern from a geometric sequence and write the formula for extending it. The instructional activity includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

A Cylinder Workshop
Students work with given formulas to solve for specific variables. The calculation of the volume of a cylinder and the change in volume when there is a constant surface area is analyzed in this lesson.

Introduction to Tangent Lines using the TI-Nspire
Learners make mathematical argument using the concept of Limit. In this algebra lesson, student calculate the instantaneous rate of change from the linear graph. They use a TI-calculator to create a visual of the graphs.
Curated OER
The Truth About Triangles and Squares
Fourth graders investigate the patterns associated with both triangular and square numbers. They use counters as manipulatives to depict the numbers as needed but focus on problem solving using mental math techniques.
Curated OER
Application of Parabolas
Students graph quadratic equations. In this algebra lesson plan, students relate the parabola to real life applications. They identify the maximum and minimum of the parabola.
Curated OER
Describing Patterns
Fourth graders investigate repeating and growing patterns. Models, graphs and words are used to describe, extend and represent patterns. Students use evidence from models and graphs to support the identification of patterns.

Parabolas Exist Where?
Young scholars recognize how parabolas are used in architecture and calculate a constant of variation.
