This lesson unit is intended to help teachers assess how well students are able to visualize two-dimensional cross-sections of representations of three-dimensional objects. In particular, the lesson will help you identify and help students who have difficulties recognizing and drawing two-dimensional cross-sections at different points along a plane of a representation of a three-dimensional object.

Students will create a 3D model comprised of 3 different shapes. This will be done with Play-doh or in Tinkercad. They will then find the volume and surface area of the composite 3D shape.

A five day unit for use after student have learned area and volume formulas for 2D and 3D shapes.  This series of lessons connects geomery with history as students explore the size of traditional Native American homes and the space each person would have had within the home. 

This lesson unit is intended to help teahcers assess how well students solve problems involving measurement, and in particular, to identify and help students who have the following difficulties; computing measurements using formulas; decomposing compound shapes into simpler ones; using right triangles and their properties to solve real-world problems.

The purpose of this task is to use geometric and algebraic reasoning to model a real-life scenario. In particular, students are in several places (implicitly or explicitly) to reason as to when making approximations is reasonable and when to round, when to use equalities vs. inequalities, and the choice of units to work with (e.g., mm vs. cm).

In this lesson, students will use formulas they have explored for the volume of a cylinder and convert them into the same volume for rectangular prisms while trying to minimize the surface area. Various real world cylindrical objects will be measured and converted into a prism to hold the same volume. As an extension, students may design and create a rectangular prism container according to their dimensions to compare and contrast with the cylinder.

The purpose of the task is to analyze a plausible real-life scenario using a geometric model. The task requires knowledge of volume formulas for cylinders and cones, some geometric reasoning involving similar triangles, and pays attention to reasonable approximations and maintaining reasonable levels of accuracy throughout.

This lesson unit is intended to help teachers assess how well students are able to: translate between the equations of circles and their geometric features; and sketch a circle from its equation.

This lesson unit is intended to help teachers assess how well students are able to solve problems involving area and volume, and in particular, to help you identify and assist students who have difficulties with the following: computing perimeters, areas and volumes using formulas; and finding the relationships between perimeters, areas, and volumes of shapes after scaling.

Students are asked to use their knowledge of volume of spheres in a real life problem.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Charles and Olivia are trying to estimate the volume of water that could be held by the figure shown below, which is 10 feet high and has a circular to...

Authors: Tiffany Lodholz, Morgan May, Jenny GrimesSchool: High Marq Environmental Charter School, Montello School DistrictUnit Title: Garden MathGrade Level: 7-12Content Area(s): Environmental Science, MathematicsContext:High Marq Environmental Charter School is a project and place based school that serves grades 7-12 in Marquette County, Wisconsin. Each week our students participate in a full day field experience designed to connect, explore and engage with the outdoors. These five lessons were all a part of those experiences. Our focus this year was on gardening. All of these lessons took place in the school garden on campus, Our school district has a greenhouse for us to start seeds in and our garden uses primarily raised beds. The students also traveled to a local greenhouse to purchase supplemental plants, soil, mulch, hay, and other accessories.

Module 3, Extending to Three Dimensions, builds on students’ understanding of congruence in Module 1 and similarity in Module 2 to prove volume formulas for solids. The student materials consist of the student pages for each lesson in Module 3. The copy ready materials are a collection of the module assessments, lesson exit tickets and fluency exercises from the teacher materials.

El módulo 3, que se extiende a tres dimensiones, se basa en la comprensión de los estudiantes de la congruencia en el módulo 1 y la similitud en el módulo 2 para probar fórmulas de volumen para sólidos. Los materiales estudiantiles consisten en las páginas del estudiante para cada lección en el módulo 3. Los materiales listos para la copia son una colección de las evaluaciones del módulo, boletos de salida de la lección y ejercicios de fluidez de los materiales del maestro.

Students build scale models of objects of their choice. In class they measure the original object and pick a scale, deciding either to scale it up or scale it down. Then they create the models at home. Students give two presentations along the way, one after their calculations are done, and another after the models are completed. They learn how engineers use scale models in their designs of structures, products and systems. Two student worksheets as well as rubrics for project and presentation expectations and grading are provided.

In this activity, students will find surface area and volume of objects the teacher provides or students bring in.

This formula sheet my students to use for reference when calculating surface area and volume.
