Creating a Reflection
Investigate geometric reflections in this geometry instructional activity. Create geometric reflections that show the reflection across the x and y axis of a coordinate graph. Learners watch a teacher demonstration before proceeding on...
Curated OER
Patterns to the Rescue
Students watch the Cyberchase episode, "The Poddleville Case" and play online games to examine how patterns are sequences that repeat or change in an orderly way. The lesson culminates with students creating their own patterns to use in...
Curated OER
Geoboard Squares
Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...
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
Tessellations
Students learn and review basic geometric terms, definitions, and theory, including regular polygons, lines, angles, points, etc. They make a tessellating stamp and create a repeating work of art.
Curated OER
Shapes and Introduction to Geometry
Students make a quilt. In this geometry instructional activity, students discuss patchwork quilts and learn some different geometric shapes and patterns that are commonly used. Students explore designs with triangles and squares and then...
Curated OER
An Introduction to Sequences
Fourth graders are introduced to arithmetic and geometric sequences. In this mathematics lesson, 4th graders produce a variety of sequences by varying the starting number, multiplier, and the add-on number.

Volume of Regular and Irregular Objects
Fifth graders examine patterns and relate to equations to solve math problems. In this patterns lesson, 5th graders diagram, graph, use models and use tables to solve equations for real world problems.
Pennsylvania Department of Education
Volume of Compound Figures
Fifth graders use patterns, models and relationships to solve equations. In this equations lesson, 5th graders define vocabulary for equations and complete worksheets explaining variables and solving problems.
Curated OER
Exploration with Geometric Solids
Young scholars reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

I. M. Pei and the Geometry of the NGA
Students compare design elements in neoclassical and modern architecture. They review knowledge of triangles and quadrilaterals and design a geometric pattern using Pei's polygons They create a city plan using a variety of lines and...
Curated OER
Introducing Powers and Models
Students construct two dimensional models to illustrate squared numbers. For this geometry lesson, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between various...
Curated OER
Visualizing Multiplication
Upper graders represent multiplication of a two-digit number by a two-digit number as the area of a rectangle with dimensions of the two factors. They find patterns for the number of different base ten blocks in a rectangle representing...
