Strand: GEOMETRY - Modeling With Geometry (G.MG)

Apply geometric concepts in modeling situations (Standards G.MG.1–3).-
A Ton of Snow

The goal of this task is to examine a mathematical statement about the mass of snow, hopefully providing some stimulating thought to go along with the very arduous and demanding physical exercise. -
Access Ramp - Student Task

This task has students design an access ramp, which complies with the Americans with Disabilities Act (ADA) requirements and include pricing based on local costs. -
Archimedes and the King's crown

This problem combines the ideas of ratio and proportion within the context of density of matter. -
Eratosthenes and the circumference of the earth

This task is designed for the student to apply geometric concepts in modeling situations. -
Fences - student task

This task has students design a fence that meets the city ordinances and the client's specifications. -
Framing a House - student task

This task has students recreate house plans on graph paper and then determine how many linear feet of wall plate material will be needed. -
GEOMETRY - Modeling With Geometry (G.MG) - Sec Math III Core Guide

The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for the Secondary Mathematics III - Modeling with Geometry (G.MG). -
Global Positioning System II

Reflective of the modernness of the technology involved, this is a challenging geometric modelling task in which students discover from scratch the geometric principles underlying the software used by GPS systems. -
Hexagonal Pattern of Beehives

The goal of this task is to use geometry study the structure of beehives. -
How far is the horizon?

The purpose of this modeling task is to have students use mathematics to answer a question in a real-world context using mathematical tools that should be very familiar to them. The task gets at particular aspects of the modeling process, namely, it requires them to make reasonable assumptions and find information that is not provided in the task statement. -
How many cells are in the human body?

The purpose of this task is for students to apply the concepts of mass, volume, and density in a real-world context. -
How many leaves on a tree?

This is a mathematical modeling task aimed at making a reasonable estimate for something which is too large to count accurately, the number of leaves on a tree. -
How many leaves on a tree? (Version 2)

Teachers who use this version of the task will need to bring tree leaves (or prepare a good sketch of a tree leaf) to class so that they can work on and discuss how to approximate the area of an irregular shape like a leaf. -
How thick is a soda can? Variation I

This task's main goal is to provide a familiar context and a straightforward question which require a variety of tools to solve: modeling a situation with geometry, paying close attention to units, and converting units. -
How thick is a soda can? Variation II

This is a variation of ''How thick is a soda can? Variation I'' which allows students to work independently and think about how they can determine how thick a soda can is. -
Ice Cream Cone

This rich task is an excellent example of geometric concepts in a modeling situation and is accessible to all students. In this task, students will provide a sketch of a paper ice cream cone wrapper, use the sketch to develop a formula for the surface area of the wrapper, and estimate the maximum number of wrappers that could be cut from a rectangular piece of paper. -
Image Tool

Students are able to explore scale by measuring angles in various images in this activity in order to better understand ratio and proportion. -
Indiana Jones and the Golden Statue

The goal of this task is to provide a introduction to the sometimes subtle use of density and units related to density, in a simple and fun context with minimal geometric complexity. -
Introduction to the Materials (Math 3)

Introduction to the Materials in the Mathematics Three of the The MVP classroom experience begins by confronting students with an engaging task and then invites them to grapple with solving it. As students ideas emerge, take form, and are shared, the teacher orchestrates the student discussions and explorations towards a focused mathematical goal. As conjectures are made and explored, they evolve into mathematical concepts that the community of learners begins to embrace as effective strategies for analyzing and solving problems. -
Miniature Golf - student task

This task requires students to redesign a miniature golf course to make it more challenging. -
Modeling: Rolling Cups

This lesson unit is intended to help educators assess how well students are able to choose appropriate mathematics to solve a non-routine problem, generate useful data by systematically controlling variables, and develop experimental and analytical models of a physical situation. -
Module 5: Modeling with Geometry - Student Edition (Math 3)

The Mathematics Vision Project, Secondary Math Three Module 5, Geometric Modeling, begins with students visualizing two-dimensional cross sections of three-dimensional objects and solids of rotation. They learn to approximate the volume of an irregular solid by decomposing it into cylinders, frustrums, and cones with volumes that can be easily calculated. -
Module 5: Modeling with Geometry - Teacher Edition (Math 3)

The Mathematics Vision Project, Secondary Math Three Module 5, Geometric Modeling, begins with students visualizing two-dimensional cross sections of three-dimensional objects and solids of rotation. They learn to approximate the volume of an irregular solid by decomposing it into cylinders, frustrums, and cones with volumes that can be easily calculated. -
Paper Clip

This high level task is an example of applying geometric methods to solve design problems and satisfy physical constraints. -
Regular Tessellations of the plane

This task examines the ways in which the plane can be covered by regular polygons in a very strict arrangement called a regular tessellation. The goal of the task is to use algebra in order to understand which tessellations of the plane with regular polygons are possible. -
Running around a track I

This task uses geometry to find the perimeter of the track. -
Running around a track II

The goal of this task is to model a familiar object, an Olympic track, using geometric shapes. -
Satellite

This task is an example of applying geometric methods to solve design problems and satisfy physical constraints. -
Solar Eclipse

Total solar eclipses are quite rare, so much so that they make the news when they do occur. This task explores some of the reasons why. -
Solving Quadratic Equations: Cutting Corners

This lesson unit is intended to help educators assess how well students are able to solve quadratics in one variable. -
Stairway - Student Task

This task students to design a stairway for a custom home. They will need to gather information regarding design, safety, and the utility of staircases. -
Storage Shed - student task

Students are going to build storage sheds as a fund raising project, but before they can start they must determine the best dimensions for the shed, make scale drawings and decide on how much to charge for each shed. -
Tennis Balls in a Can

This task is inspired by the derivation of the volume formula for the sphere. -
The Lighthouse Problem

In addition to the purely geometric and trigonometric aspects of the task, this problem asks students to model phenomena on the surface of the earth. -
Tilt of earth's axis and the four seasons

This task gives students a chance to relate their weather experiences with a simple geometric model which explains why the seasons occur. -
Toilet Roll

The purpose of this task is to engage students in geometric modeling, and in particular to deduce algebraic relationships between variables stemming from geometric constraints. -
