Students practice assessing how to apply the formulas for the area of parallelograms and triangles. They recount the contributions of Pythagoras and apply the theories of the Pythagorean theorem in a group project to calculate the...

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson plan, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional...

In this scales learning exercise, students find the weight of the shapes on the scale by comparing it to the other side, and make up their own problems. Students complete 5 sets of problems.

Second graders manipulate triangles to discover the concepts of slides, flips and turns of a geometric shape.

Young scholars find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped...

Students identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have been...

Sixth graders graph translations (slides) and reflections (flips) on a coordinate plane. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders write a paragraph telling...

Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...

Pupils investigate inscribing a circle in a triangle. They use Cabri Jr. to draw a triangle, locate the incenter, and use the distance from the incenter to a side of the triangle to inscribe a circle. The dynamic nature of the geometry...

Pupils explore the midsegment of a triangle in the geometry instructional activity. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Students participate in a series of challenging math lessons designed to engage their critical thinking skills. In these real-world problem solving lessons, student solve symmetry and repeated pattern problems, make lists/tables to...

Third graders understand what a line of symmetry is and how to draw symmetrically. In this monster symmetry lesson, 3rd graders create an original monster that is symmetrical. Students participate in additional symmetry activities.

Students graph coordinate points to create a picture of Snoopy. In this coordinate point lesson, students read a book and learn about Rene Descartes' invention, the coordinate grid.  Students graph a surprise picture on...

Teach your class to think outside the box. Scholars use the concept of equality to solve a problem in the assessment task. They determine how to use a scale to identify the one box out of a set of nine boxes that is heavier than the others.

These activities will allow students to discover the concepts of geometry through shape exploration and the creation of choreographic sequences.

In this series of STEAM activities, students will discover the concepts of geometry through shape exploration and the creation of choreographic sequences. Another activity in this module will allow students to identify shapes by applying...

Given a figure and a definition of a translation, draw the image. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Given a figure and a definition of a reflection, draw the image. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

A comprehensive list of 2D shapes and 3D solids with everything from a triangle to a dodecahedron. Includes illustrations and short descriptions of attributes for each.

The instructional tool explores various geometric solids and their properties. Student can manipulate and color the different shapes. Learners examine the edges, faces, and vertices of the different solid figures.

This task challenges a students knowledge of 2-dimensional geometrical shapes to sort shapes and to design a shape that has a given set of attributes.

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,...

This task challenges a student to use knowledge of geometrical attributes to identify and describe shapes.
