Idaho Region 2 educators:
Fermi Problems |K-12th| - Enrico Fermi was a mathematician who made educated guesses about hard-to-quantify situations -- for example "how long would it take to actually count to one million?" The linked site is one of many that outlines a great list of "Fermi" problems or prompts that can be used as the foundation for modeling tasks. These are not indexed by grade level or standard, but these are great examples to help you identify your own questions you might prompt your students to ask.
PBLWorks Project Library and Project Designer via the Buck Institute for Education - While a few of the math PBL resources are free, most of the 72 "gold-standard" projects require paying $40 for the "Project Designer" to access. PBLWorks really is the gold standard for successful PBL design: many colleges use their model and materials when teaching project-based learning models to pre-service teachers. Example free project: Planning for the Future.
Defined Learning PBL - A paid project library that includes well-organized, cross-curricular PBL projects and units (such as this Zip-line design project).
COMAP Consortium for Mathematics and its Applications free educator resources - includes teacher and student resources for project-based modeling tasks and units. For example, Invasive Species A Module in Planning for Sustainability (Teacher), includes teacher planning materials, student workbooks, a career and college planning section on "jobs that use skills learned in this module," vocabulary and research printouts, a Powerpoint for the paramecium growth simulation, NGSS, CCSM, standards. Most of the projects have both math and science standards included, and some also include CCSE. Projects and units are not all designed with the same format and are of varying quality.
Math Works Modeling Challenge Archive Free - Each year, M3C hosts a contest for teams of high-school students with real-world modeling prompts. Click on the years at the top of the page to see the prompts for each year (and the winning responses). The prompts are well-defined if you click on "The Problem" on the right-hand side of the page for each year. They pay all-expenses for the finalist teams to attend the conference and present their projects each year.
Connecting Industry to Math Instruction (CIMI) Activities - Free - An NSF-funded project with professional-quality context videos from industry professionals, lesson plans, desmos activities, and activity sheets. Categories include functions, trigonometry, statistics, modeling, and matrices. Often includes growth mindset language and focus on mathematical practices from industry folks and students. Actively advertises enrollment at Wake Tech College in the videos.
Secondary Math PBI |6th - 12th| - For folks who have a purchased copy of the book "Implementing Problem-Based Instruction in Secondary Mathematics Classrooms", this site gives around 20 example projects and resources as outlined in the book, sorted by 6-12 course then by concept. The framework they use is heavily influence by PBL works, but brings some unique ideas to the table as well.
Illustrative Mathematics Modeling Prompts for Algebra 1, Geometry, and Algebra 2, include a solid framework for presenting modeling tasks tailored to the needs of students, as well as about 9-12 modeling prompts per course and when to use them.
Small Group Mathematical Modeling (SGMM) @ Purdue outlines some upper high school or college level Model Eliciting Activities (MEAS) focused on engineering principles.
Pedagogy in Action provides Model Eliciting Activities (MEAs) that are focused on statistical concepts and can be adapted for junior high, high school, and college-level instruction.
Ohio State Mathematics Modeling and Reasoning Course Pilot has an interesting Scope and Sequence for a modeling focused course and offers free training and support to any teachers willing to travel for initial training.
Mathematics Lessons for High School Career and Technical Education - Includes some teacher/student materials for tasks in Automotive/Diesel Technology, Culinary Arts, Health Occupations, Law Enforcement, and Welding. Created by an Idaho Math teacher at Cossa Academy.
