Visual Patterns in Tessellations
Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Mathematics: Growing Patterns
Learners graph growing patterns using ordered pairs on a coordinate grid. They read The Fly on the Ceiling, a Math Myth.
Curated OER
Polynomial Multiplication
Students review information about how to multiply polynomials and then work in pairs to complete a worksheet. They use graphing calculations to help them solve their math problems.

Quilting Geometry
Study geometry through the concept of quilt design. High schoolers examine the geometric shapes in various quilts and then create their own quilts using geometric shapes that fit together. In the end, they write a paragraph to describe...
Curated OER
Patterns and Functions
Students investigate properties of perimeter and area. In this middle school mathematics lesson, students explore patterns in a problem solving context. Students model and solve problems using various representations for the data as...
Curated OER
Cartesian Coordinate System
Students explore the Cartesian coordinate plane and plot points on the graph. They interpret coordinates for a point from the graph and give the ratio of rise over run for slope.
Curated OER
Constructing Tangrams
Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams activity, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...
Curated OER
The Function Box
Students explore arithmetic and numerical patterns. After observing a teacher created function box, students describe a pattern and predict what will "come out" of the function box. They explore patterns such as geometric shapes,...
Curated OER
Cartesian Coordinate System
Students explore the concept of the coordinate plane. In this coordinate plane instructional activity, students graph points on the coordinate plane using an applet. Students graph functions using an applet. Students play a Maze Game...
Curated OER
Visual Patterns in Tessellations
Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.
Curated OER
Repeating Patterns
Learners explore growth patterns by using manipulatives such as pattern blocks, investigate growth pattern of pattern, record growth in T-chart, describe how pattern is growing, and predict number of blocks needed to extend pattern.
Curated OER
Double, Double: Looking at the Effect of Change on Perimeter, Area and Volume
Students explore perimeter, volume, and area. For this math lesson, students explore how changes in dimensions of geometric shapes affect the perimeter, area and volume of the various shapes. Students investigate the results when the...
Curated OER
Pythagorean Theorem
Students find the different ratios of a triangle. In this geometry lesson, students use the Pythagorean Theorem to solve for missing sides and angles on a right triangle. They use a robot to create a right triangle.
Curated OER
Prime and Composite Numbers with use of manipulatives (Elementary, Mathematics)
Students learn what prime and composite numbers are. They learn how to identify them by working in a group and demonstrating an understanding of one work problem with 100% accuracy using the manipulatives provided.
Curated OER
The Function Box
Students look around classroom and identify any patterns they see, describe patterns and explain why they are patterns, use pencil to demonstrate arithmetic patterns by tapping, practice predicting patterns by using Function Box, and...

Figure This!
Second graders explore the concept of inequalities. They use the mathematical symbols =, <, > to show relationships among numbers. Students devise and use problem solving strategies to explore the situation.
