This resource will enable students to determine flawed reasoning in a fraction comparison with unlike numerators and denominators.

This resource includes a flawed reasoning task that reflects 5.NF.5. Students must find the flaw in an argument and present it correctly. Then, they should provide a reasoning behind their thinking.

This OER explores the basic organization of the Pythagorean Solids. It contains both an activity as well as resources for further exploration. It is a product of the OU Academy of the Lynx, developed in conjunction with the Galileo's World Exhibition at the University of Oklahoma.

This resource includes two multi-step tasks where students connect diagrams and equations in order to solve real world problems. This task includes skills learned in the common core standard 5.NF.2

How can you use the Engineering Design Process to access a geographically inaccessible location to deliver supplies?

Students will review and practice the concepts of adding fractions. This is a great tool to use for extra practice or review for a test.

This resource includes three tasks surrounding the Common Core Standard 5.NF.2 - Adding and Subtracting Mixed Numbers with Unlike Denominators Using an Open Number Line and Fraction Equivalence. The tasks involves looking at real Maryland snowstorm data and each task builds off the previous task.

Project Based Learning for Algebra 1 Students. Students must collect, analyze, and graph date.

Algebra and Trigonometry 2e provides a comprehensive exploration of mathematical principles and meets scope and sequence requirements for a typical introductory algebra and trigonometry course. The modular approach and the richness of content ensure that the book addresses the needs of a variety of courses. Algebra and Trigonometry 2e offers a wealth of examples with detailed, conceptual explanations, building a strong foundation in the material before asking students to apply what they’ve learned.Attribution: This work "Algebra and Trigonometry, 2e" by Jay Abramson is licensed under a Creative Commons Attribution 4.0 International License, except where otherwise noted.  

Students will practice and review the concepts of angle relationships. This could be used as a review tool.

In this lesson, learners will use creativity as they think about future business decisions and activities, including creating a budget and calculating the price points of different jewelry pieces. Targeted skills for this lesson include career, life, entrepreneurship, and employability. The learners will describe five modern trends of fashion jewelry in the region, country and worldwide, calculate the price point, and design an original piece of jewelry. This lesson was designed for one, sixty-minute, class period but can be adjusted. The learners in this lesson are presumed to be young women or men, ages 15-18, in a secondary classroom. The lesson can be a part of math, art, or business courses. Significantly, the author licensed this lesson to be reused and modified to meet the needs of any users.

STEM focused lesson that incorporates hands on and computer based 3D design. Grade specific math concepts such as budgets, percentages, and square footage is applied.

This video module presents an introduction to cryptography - the method of sending messages in such a way that only the intended recipients can understand them. In this very interactive lesson, students will build three different devices for cryptography and will learn how to encrypt and decrypt messages. There are no prerequisites for this lesson, and it has intentionally been designed in a way that can be adapted to many audiences. It is fully appropriate in a high school level math or computer science class where the teacher can use it to motivate probability/statistics or programming exercises. nteractive lesson, students will learn to build the cryptography devices and will learn how to send and ''crack'' secret messages.

This lesson will focus on applying basic math skills to determine current inventory on hand at a business or in the home, and calculate the number of items needed. In addition, learners will determine the costs to replace items and apply the amount to an overall budget.

This site provides lectures and guided lecture notes for students for a second-semester calculus course.

In this lesson, students calculate their own carbon footprint using Peter Kalmus's methodology in his book Being the Change: Live Well and Spark a Climate Revolution.

Step 1 - Inquire: Students watch a short video on the climate crisis. Students engage in a brief discussion on the prompt "Do my individual actions matter?"

Step 2 - Investigate: Students calculate their own carbon footprints.

Step 3 - Inspire: Students engage in a discussion, reflecting on this activity and the importance of individual actions.

This unit provides Common-Core aligned lessons based for Math 3, English 10, and Biology (NGSS Standards). The subjects are linked by a text on climate change, and they hit the standards of argumentation for English, comparing functions in Math 3, and human effects on environment in Biology.
