Geometry Practice: Classifying Solids #2
For this solids worksheet, students identify the characteristics of solids. They name solids and determine the number of faces. This three-page worksheet contains seventeen problems. Answers are listed on the last page.
Curated OER
Classifying Three-Dimensional Shapes
Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...
Curated OER
Shape Makers
Classify and explore shapes by giving learners opportunities to handle, describe and classify 2D and 3D shapes. Primary learners will sort objects such as triangles, squares, oblongs, circles, ovals, pentagons, hexagons, diamonds, boxes,...
Curated OER
What a View!
Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...
Curated OER
Poly-Mania
This hands-on lesson plan takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws....
Curated OER
Marshmallow Figures
Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3 dimensional...
Curated OER
Strongest Polygon
Young scholars define and identify shapes by name. In this geometry instructional activity, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.
Curated OER
Tunnel Traps
Young scholars identify shapes that match specific shape descriptions involving a range of geometric terms and correct polygon names. They utilize a mathematics educational software program to gain practice.
Curated OER
Squares to Compare
Young scholars investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)
Curated OER
Poison Boxes
Students utilize the Poison Boxes activity on The Nature Park is used to practice the recognition of 2D shapes and their properties. They utilize a mathematics educational software program to gain practice.
Curated OER
A Snap at Geometry
Young scholars study geometric images and polyhedrons. In this geometry instructional activity, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Young scholars watch a video,...
Curated OER
Solids...Volume and Surface Area
In this volume and surface area worksheet, students find the volume and surface area of different solid figures. Students complete 8 problems.
Curated OER
Ancient Aztecs
Is it a calendar? A religious symbol? A political statement? One thing for certain is that Aztec sun stone designs remain an important symbol in Mexican cultural art. Young artists craft their own Aztec Sun design incorporating ideas...
Curated OER
Incredible Edible Bridges
Young scholars create a bridge using engineering and geometric concepts. In this geometry lesson, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using problem solving...
Curated OER
Polydron Fun
Students investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...
Curated OER
Seeing Seeds
Students identify different types of seeds and label the outside and inside of a seed. Students create their own model of a bean seed.
