Fourth graders review their prior knowledge on the concept of pi. Using broken pieces of pottery, they calculate the circumference from a section of the circle. In teams, they compete against one another to get the most accurate...

High schoolers practice identifying right, vertical, and adjacent angles using a Smartboard. They then determine measurements of all of the angles when only one measurement is given.

Ninth graders demonstrate application of area, surface, and volume. They apply formulas to a model of the classroom so they can determine the volume and surface area of the classroom.

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.

Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.

Investigate the concepts of area, volume, 3D shapes, and nets using this interactive Learn Alberta math. The solid shapes focused on this exploration include rectangular and triangular prisms, rectangular and triangular pyramids,...

The goal of this PBS lesson is for young scholars to apply spatial reasoning, problem solving, and critical thinking skills to assess which regular polygons will tessellate. A detailed lesson plan that includes related worksheets, lesson...

An integrated geometry instructional activity on spatial sense in which students identify and use different shapes to create a tessellation. "Through a variety of modalities such as writing, music, art, poetry, and literature, students...

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

The class has been contracted to work for a box factory. They are to make cube shaped jewelry boxes. Students determine how many different nets are possible and then analyze the resulting cubes. This real-world situation helps to develop...

Using calculators, learners investigate quadratic functions using geometric toothpick designs in this lesson that with a review of transformations of quadratic functions, vertical and horizontal shifts, and stretches and shrinks.
