Terrific Tangrams
Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.
Curated OER
What Is Your Point?
Sixth graders identify the x and y axes in a coordinate plane and identifies the coordinates of a given point in the first quadrant. They plot specific points in the first quadrant of the Cartesian coordinate system.
Curated OER
Using a Multi- Sensory Approach
Learners identify the slope of a line given two points on the line. In this algebra lesson, students solve linear equations by finding and comparing slopes of lines. They differentiate between the steepness of the slope and the line.
Curated OER
Rotation Symmetry
Students investigate the concept of symmetry by using various examples and performing independent practice with scaffolding provided by the teacher. They review reflection symmetry and cover the new rotation symmetry using manipuatives.
Curated OER
CEEnBoT Stories
Students identify the slope of a line as negative, positive, zero or undefined. In this algebra lesson, students identify the distance versus the time using graphs of linear equation. They use the robot and the CEENBoT program to analyze...
Curated OER
Tilted Squares and Right Triangles
Students investigate squares. They generate patterns from structured situations and find a rule for the general term and express it using words and symbols. Students generate patterns from a rule and substitute values and formulas.
Curated OER
Symmetry with Manipulatives
First graders investigate symmetry in patterns by utilizing unifix cubes. In this pattern lesson, 1st graders practice creating patterns that are perfectly symmetrical no matter which way it's looked at. Students utilize original...
Curated OER
Math/Quilt Connection
Students explore quilting. In this math patterns instructional activity, students define the perimeter of a quilt border, create tessellations using geometric shapes, and detemine the area of a quilt.
Curated OER
How Tall Is That Flag Pole?
Students examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.
Curated OER
Medieval Mathematicians and Whimsical Windows
Third graders demonstrate their mathematical knowledge of symmetry and reflection using congruent geometric shapes while working as an artist and mathematician looking at a medieval-styled stained glass window.
Curated OER
Learning about Shapes with Tangrams and the Net
