The Topsy-Turvy Twins
Fourth graders read the problem and brainstorm for ways to solve the problem - list these on the board for the students to refer to as they solve the problem. They work in pairs and focus on the strategy selected.

The Truth About Triangles and Squares
Fourth graders investigate the patterns associated with both triangular and square numbers. They use counters as manipulatives to depict the numbers as needed but focus on problem solving using mental math techniques.
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.

Creating Polygons
Students describe, make and compare polygons. In this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
Geometry and Symmetry
Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

Carbondale: The Biography of a Coal Town
Students use a brief history of the growth and decline of the anthracite region in the state to create a photograph and map "peak shaped" time line. They practice map and photo analysis strategies to "read" photographs and maps.
Curated OER
Irregular Fractals
Pupils study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
