Triangle Congruence with Rigid Motion
Combine transformations and triangle congruence in a single lesson. Scholars learn to view congruent triangles as a rigid transformation. Using triangle congruence criteria, learners identify congruent triangles and the rigid...
Curated OER
Angles, Parallel Lines, and Polygons
Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Translation and Reflection
Bring about the change you want to see in the world or at least in your lesson plans. Young mathematicians learn about translation and reflections by applying them to polygons on the coordinate plane. Results provide data to develop...
Curated OER
Relations
Students identify, compare, and analyze shapes and numbers. In this analogies and comparison math lesson, students warm up by completing 4 worksheets to familiarize themselves with analogies. In small groups, students are challenged to...
Curated OER
One Good Turn Deserves Another
Students make observations about shapes and 1-, 2-, and 3-dimensional objects. They conduct observations and make predictions regarding transformations of simple geometric shapes. They identify shapes that occur in household items.
Curated OER
Tessellating Ceiling Tiles
Students transform polygons. In this tessellating lesson, students design a picture containing a translation and a rotation. They create a template of a translation or a rotation. Students tessellate and decorate a ceiling tile.
Curated OER
Powerful Polygons
Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...
Curated OER
The Tipping Point
Young scholars rewrite word problems and solve using math. For this word problem lesson, students gather data and observe the data. They relate this process to the scientific method and math. They review their data to be able to answer...

Scaled Rubber Band Drawings
Students demonstrate the process of creating a scaled rubber band enlargement of a simple drawing. They observe and discuss a teacher-led demonstration, and create a scaled rubber band enlargement of simple drawings and their invention...
Curated OER
Teaching Polygons using Technology
Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...

How Machines Help Us Stay Healthy
Students visit different departments at a local hospital to see how machines help peoples such as the CAT scan machine. They build a model of such a machine that shows how patients are moved in and out of the machine.
Curated OER
Introduction to Fractals: Geometric Fractals
Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Butterfly Adventure
Students in second grade are paired with fifth grade computer research buddies. They observe the characteristics of caterpillars, and identify the four stages of the caterpillar to butterfly life cycle. They graph the number of...
Curated OER
Rep Tiles
Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...
Curated OER
The Quirky Quadrilateral
Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...
