Is This a Rectangle?
How do you show that something is a rectangle? This activity starts with four coordinate points and asks young geometers to explain whether they create a rectangle. Knowledge from both geometry and algebra come into play here, as well as, exploring many different approaches to solve this problem; making this a good small group activity.

Carrying a Figure onto Itself
Your geometry learners will be pros at transforming figures using rotations and reflections after this hands-on lesson. Collaborative groups, with access to geometric construction tools, analyze and report the series of reflections and rotations that were used to produce an image from its pre-image.

New Review Recognizing Geometric Shapes
Young mathematicians explore the beauty of geometry with this cross-curricular math and visual arts lesson. Over the course of four or five days, children observe and discuss the geometric and organic shapes found in two pieces of artwork, before eventually creating there own mobiles that demonstrate their newly acquired knowledge about shapes.

Sailing with Congruency
Young geometers will have fun with this real-world application of a geometry theorem. Working in groups, they explore the design of sailboats and must come up with a convincing argument about how the manufacturer can save time and money. The argument requires proving that each point on the perpendicular bisector of a segment is equidistant from the endpoints of the segment.

Constructing a square inscribed in a circle
Here is an activity that focuses on the actual construction of the square inscribed in a circle. The lesson plan allows for the use of dot paper or graph paper with straight edges and protractors, or dynamic geometry software programs. After construction, learners verify that the figure is a square.

First to Finish
Geometry learners practice copying angles and line segments as they plan a path through an obstacle course with the goal to finish first. They have requirements, but are encouraged to explore different routes. Lastly, learners share and defend their choice of pathways.

Linear and Exponential Change: Comparing Growth Rates
This thirteen-page PowerPoint presentation guides geometry learners in interpreting linear functions, linear data and their trend lines, the consequences of their constant rate of change, and growth rate. Real-life models including step-by-step solutions, graphs, and functions are used to compare the characteristics of linear and non-linear functions, especially exponential verses linear.

Pupils explore the concept of pyramids. They determine if two sides of a pyramid are perpendicular using a graphing calculator, then discuss parallel and perpendicular lines and how to determine if two lines are parallel or perpendicular. Learners find the equations of sides of a pyramid to determine if two sides of a pyramid are parallel or perpendicular.
