Congruent Trianges - Is This Enough Information?
Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.

Measuring Angles
Identifying and measuring angles with a protractor can provide a fun way for students to learn this mathematical concept.
Curated OER
The Mandelbrot Set
Students are introduced to the notion of a complex number and function iteration in order to motivate the discussion of Julia sets and the Mandelbrot set.
Curated OER
Transversal and Angles
Tenth graders identify angles formed by parallel lines and a transversal. Using meter sticks and bolts, they perform hands-on activities to demonstrate the properties of parallel lines and congruent angles. They color code diagrams to...

Visual Patterns in Tessellations
Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.
Curated OER
Translations, Reflections, and Rotations
Students are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.
Curated OER
Acceptance Through Patchwork
Students are asked to look at differences in people and accept those differences but to examine that people are more alike than different. The lesson has the central focus of investigating diversity.

Cook Me Up Some Equations
Students study a variety of math concepts in the context of cooking up a meal. In this math lesson plan, students calculate surface area and volume. They draw and interpret different types of graphs.
Curated OER
The Mandelbrot Set
Students explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.
Curated OER
Your Body's Building Blocks
Students study the elements of the Periodic Table as they relate to the building blocks of the body. They experiment to measure the amount of iron in the body.
Curated OER
Properties of Fractals
Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...
