Curated OER
The Delta Flier
Students make calculations in order to construct a kite in the shape of an isosceles right triangle. In this kite instructional activity students calculate altitude of their flying kites using a formula.
Curated OER
Translations, Reflections, and Rotations
Students are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.
Curated OER
Transformation: Reflection
Tenth graders identify and analyze appropriate key vocabulary terms associated with transformations and reflection. Students experience creating and recognizing reflection with hands-on manipulations. Students discover real-world...
Curated OER
Creating Fractals
Students solve problems using fractals. In this geometry lesson, students identify properties of fractals. They find patterns in their surroundings and relate it to the real world and math.
Curated OER
Geometry and Quilting
Fourth graders combine geometry and language arts skills while examining quilt-making. After identifying the geometric shapes contained in quilts, they write stories to encompass the quilt border. Students conclude by creating and...
Curated OER
Isosceles Triangles
Students identify the properties of an isosceles triangle. In this geometry lesson, students find the midpoint, median and angle bisector of a triangle. They construct angle bisectors and measure missing angles.
Curated OER
Similar and Congruent Triangles
Students create and classify different types of triangles using an online geo-board. They explore the concepts of similar and congruent as they discover how to draw similar and congruent triangles.
Curated OER
Transforming Triangles
Sixth graders examine how to graph translations (slides) and reflections (flips) on a coordinate plane. They practice the slides and flips kinesthetically and apply it to a worksheet working with triangles.
Curated OER
Friendship Quilt
Third graders name different kinds of shapes and then discuss what they know about them an what they would like to learn using a K-W-L chart whole group. They listen to the book, THE GREEDY TRIANGLE and then retell it to the class. They...
Curated OER
Mirror Tool
Students define properties of polygons. In this geometry lesson, students differentiate between similar and congruent polygons. They identify and use the properties of solids to solve problems.
Curated OER
Properties of 2D Shapes
In this math worksheet, students study 5 basic geometric shapes. Students write a description for each, naming the shape, telling about the edges, the lengths and the corners.
Curated OER
Geo Jammin' By DeSign - Day 4, Lesson 22: Authentic Design
Students explore the complexity of handmade quilts and their designs by looking a real life samples.
Curated OER
Origami Frogs
Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.
Curated OER
Odd Thing Out
Students listen to the math problem provided and work in groups to solve. They think about the objects and write down their information in a table. Class construct the table on a large piece of paper that can be put on the wall after the...
Curated OER
Building Paper Bridges
Young scholars construct a bridge that can hold 100 pennies. In this math instructional activity, students evaluate the strength of their bridges. They predict how much weight a bridge can hold based on its design.
