Curated OER
School Yard Park/ Ecosystem
Fifth graders examine ecosystems in their schoolyard. In this nature and ecosystem lesson, 5th graders map their schoolyard into workable plots. They classify plants and animals found in the plot. They revisit their site every two weeks...
Curated OER
Classifying Objects
Fourth graders work in small groups to sort and classify a variety of objects. They develop criteria for sorting and explain the characteristics they chose for classification. Groups record and share their classifications.
Curated OER
Acute Triangles
Learners study acute triangles. They measure angles using a protractor, then classify the triangles as either right, obtuse, or acute. Everyone creates a design for a Navajo rug using only acute triangles.
Curated OER
Neat Feet
Students view a video and discuss different kinds of feet found in the animal kingdom. They make prints using paint, rubber stamps and their own feet and then measure and compare the tracks.
Curated OER
Right Triangles
Learners classify triangles and make connections regarding angle measurements and attributes of acute, right, and obtuse triangles. They listen to teacher define and explain triangles. Everyone imagines a place where a broken wing for a...
Curated OER
Scalene Triangles
Fifth graders identify and classify scalene, equilateral, and isosceles triangles. In this triangle instructional activity, 5th graders define the different attributes of 3 types of triangles and sort them by descriptions and...
Curated OER
Shell Sort; Serving up Seafood
Students complete various small group activities to classify items and determine the types of combinations that can be made with these items. In the second lesson, students create menus for a restaurant to help them gain money sense and...
Curated OER
Circles, Rectangles, Squares, Triangles
Students identify, compare and classify the various shapes. For this shapes lesson, students listen to descriptions of shapes with words such as sides, angles, congruent, and parallel. Students then give the teacher examples of shapes...
Curated OER
Isosceles Triangles
Learners investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Learners locate the prefix "tri" in a variety of words and make connections with...
Curated OER
3-D Figures Part 1
Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.
Curated OER
Cones, Cylinders, Spheres
Students classify polygons by name and shape. In this geometry lesson, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.
Curated OER
Where Have All the Endangered Gone?
Students explore animals that are endangered. They choose an endangered animal that they would like to keep from becoming extinct. Students create a persuasive presentation to persuade someone to understand why they feel keeping their...
Curated OER
Equilateral Triangles
Students examine the attribute of equilateral triangles. In this equilateral triangle lesson, students examine a number of paper triangles to determine how they are classified. They determine how triangles are depicted in Navajo rugs.
Curated OER
3-D Figures Part 2
Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.
Curated OER
An Alien Has Landed
Students identify animals within a species by using their observation skills to record information, such as behavioral characteristics.
