Plane Shapes and Solid Shapes
The class is introduced to plane figures and solid shapes. They learn to recognize the characteristics of two and three dimensional shapes by working with cut outs of plane shapes and by touching solid objects. They explore what it means for shapes to be congruent and what line of symmetry means.
Use this activity on cross-sections of three-dimensional shapes in your math class to work on algebra or geometry Common Core standards. The lesson includes a list of relevent terminology, and a step-by-step process to illustrate the concepts with styrofoam cones and two-dimensional graphs. It also provides a link to the worksheet necessary to complete the exercise.
Discovering Math: Exploring Geometry
Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade with classmates, who calculate surface area and volume of some of the structures. Refers to a Discovery Education video/DVD to support and enrich the project; a link takes you to a website to order it. Charts mentioned are not attached.
Identify Plane Shapes and Solid Shapes
First graders explore geometric shapes. In this plane and solid shapes instructional activity, 1st graders explore visual examples of plane shapes and solids. Students also practice solving problems that their instructors model.
Plane Shapes and Solid Shapes
Students examine different shapes. In this geometry lesson, students review the names and attributes of plane and solid shapes. Students use shape cards to test their knowledge of each.
In order to better understand how to locate a plane of symmetry in 3-dimensional objects, learners create a dance. The class reviews dance and math symmetry, then they practice making symmetrical shapes and movements with a partner. They conduct a simple group dance that finishes with a discussion on finding the plane of symmetry in 3-dimensional shapes.
Dream Room Design
Junior designers brainstorm the elements that a bedroom might have, such as a bed, television, and dresser. They identify which items are needs and which are desires. They practice measurement skills in the classroom by determining its dimensions and the dimensions of various objects in it. Finally, each individual creates a sketch of their dream room and writes a descriptive essay about it. Note that even if you do not have the Share™ application that is part of the lesson plan, there is plenty here to use in your math class.
In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.
Surface Area Nets
Two-dimensional representations of three-dimensional objects are used to solve problems involving volume and surface area. Pupils utilize orthographic maps to model properties of geometric figures. This high-quality lesson presents engaging activities and worksheets embedded in the plan.
SuperShapes, Part 1; "Tri"ing Triangles
An outstanding lesson plan on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle characteristics, and the Pythagorean Theorem. Some excellent blackline masters are included in this fine plan.
Students build a castle to Ravi's design using the cubes. Students then make an original model of a solid object from diagrams which show views from the top, front, side and back. Students describe the reflection of rotational symmetry of a figure or object.
Great Shapes Alive!
Compare two- and three-dimensional shapes and construct three dimensional models from two-dimensional shapes. Diagram the shapes and reflect about the process in writing.
Draw 3 Dimensional Objects
Bring three-dimensional shapes to life in your classroom. First introduce the vocabulary of three-dimensional shapes, such as sphere, cube, and pyramid. Then, show your kids examples of how to use two-dimensional objects draw three-dimensional objects and practice drawing them.
Classifying Shapes and Figures
Fourth graders classify geometric shapes and figures. In this geometry lesson plan, 4th graders use cut-outs of shapes and identify the faces and sides of each shape. Students use marshmallows and toothpicks to construct various shapes.
Living in a Geometrical World
Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.
Conjectures for Congruence and Similarity
Eighth graders explore similar and congruent figures and objects. They are given objects, figures, and geometric terms, 8th graders classify items by property. Pupils explore sets of congruent and similiar figures and use observations and measurement to make conjectures. Students make conjectures about ratio, and proportion.
Students investigate nets as they relate to volume and area. For 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 explore the properties of these objects.
Mathematics Alive: Environment and Design of Human Habitats
Third graders explore the structural composition of buildings and houses. In this math instructional activity, 3rd graders explain how architecture is related to mathematics. They create a blueprint of a structure with at least three different spaces.
How many edges do I need to cut in order to open a cube?
Students problem solve to open a cube to create different shapes. In this problem solving lesson plan, students are given a cube and the shapes to open it up to, and they have to cut the cube open to make certain shapes. This gives them a better understanding of 3 dimensional shapes.
First graders create a map of their classroom that can be used to find a hidden treasure. They examine two- and three-dimensional objects and discover characteristics.
