This lesson provides an excellent bridge into the study of the Reconstruction era. Students will examine the roles of the president that have evolved through history and the powers of the president as prescribed in Article II of the U.S. Constitution. They will then role-play members of Lincoln’s cabinet and witnesses hold hearings on Lincoln’s Reconstruction plans.

There are several Roller Coaster rating/ranking sites online that, while taking some objective measures into account, heavily rely on subjective input to determine the rating or ranking of a particular roller coaster (e.g., an "excitement"or "experience" score of an "expert" rider to measure "thrill").

This is a lesson plan that introduces rotational and reflectional symmetry with geometric shapes, focusing on regular polygons. Notes (two copies: a student version and also an answer key, both as a Word doc and a PDF), assignment, and cut-out shapes are provided. There is a final project, with both instructions and an example included. Cover image: Christensen, K., 2022. Reflectional Symmetry of an Atom [screenshot] (Keynote presentation, Rotational and Reflectional Symmetry Assignment).

Science Phenomena: HS Physical Science - Waves and Information - The Rubens' tube was invented by German physicist Heinrich Rubens in 1905. It is a tube that is sealed at both ends in includes a flammable gas like propane. A speaker is attached to one end of the tube so sound waves can be transmitted thought the air/gas mixture. Small holes are drilled in the top of the tube and when the air/gas mixture emerges it creates a flame. As sound is played standing waves are created in the flames that change as the frequency of the waves is changed.

Consider a school where most of the students are from rural areas so they must be bused. The buses might pick up all the students and go to the elementary school and then continue from that school to pick up more students for the high school.

A clear alternative would be to have separate buses for each school even though they would need to trace over the same routes. There are, of course, restrictions on time (no student should be in the bus more than an hour), drivers, equipment, money and so forth.

How can you set up school bus routes to optimize budget dollars while balancing the time on the bus for various school groups? Build a mathematical model that could be used by various rural and perhaps urban school districts. How would you test the model prior to implementation? Prepare a short article to the school board explaining your model, its assumptions, and its results.

This lesson is to help students to understand and use the scientific method by producing a short film.

​Utah kitemaker Scott Hampton shares his passion and skill for kite making– a true nexus of art, science and math. Raised as an “army brat” and moving from school to school, he recounts how he rose in the ranks from a checked out student doodling in class to becoming a visual arts teacher and kite maker, wowing festival crowds with his unique and colorful life-like figure kites.

Finding lost objects is not always an easy task, even when you have knowledge of a general location. Consider the following scenario: you have lost a small object, such as a class ring, in a small park see map 1. It is getting dark and you have your pen light flashlight available. If your light shines on the ring, you assume that you see it. You cannot possibly search 100% of the region. Determine how you will search the park in minimum time. An average person walks approximately 4 mph. You have about 2 hours to search. Determine the chance you will find the lost object.https://mathmodels.org/Problems/2011/HIMCM-B/index.html

This resource from the National Constitution Center includes an introduction, big questions, recorded class sessions, briefing documents, slide decks, and worksheets about the second amendment of the United States Constitutuion.

In this lesson, based on the documentary Through My Eyes: The Charlie Kelman Story, students learn about the history and state-of-the-art of one of the world's most commonly performed surgical procedures--eye cataract removal and replacement.

In this lesson, students will consider the perspective of Angelina Grimké regarding the injustices of slavery. They will consider ways in which they can promote or fight for justice in their own lives.

In this lesson, students will explore the life of Thurgood Marshall and follow the development of his identity. Through his example, students will understand how they can develop and refine their identity in their own lives and, through this refinement, help advance freedom for themselves and others.

Students will design a method that applies various chemistry techniques to separate a mixture by physical means to simulate how a scientist would mitigate contamination in a stream due to run-off.

In this activity, you and your students will explore Elizabethan stage practices as the rustic yet enthusiastic amateur actors from Shakespeare's A Midsummer Night's Dream. While it's not necessary to teach Shakespeare's biography while studying his plays, sometimes opportunities to explore his world through his own eyes present themselves in his text. Students' new insights into the text will provide them with a deeper appreciation for Shakespeare’s world. This activity will take one or two class periods.

This activity helps students understand how General William Tecumseh Sherman's March to the Sea was one of the most controversial aspects of the later phases of the Civil War. Sent by Ulysses S. Grant to create havoc and destruction of all resources that would be beneficial to the enemy, Sherman began his Atlanta Campaign in May 1864. Students will view a video clip from Ken Burns: The Civil War that explains how after capturing Atlanta, Sherman marched his army to the sea, capturing the city of Savannah in December, and then marching through South Carolina into North Carolina. Students will then analyze two primary sources. Student questions follow, which can be used for general class discussion or individual assessment. Answers to the questions are included.

As online stores start to compete with traditional brick and mortar stores the goal is to combine the benefits of both types of businesses. Brick and mortar stores provide the benefit of seeing the actual items, picking up your purchase right away, and not having to pay for shipping. But, sometimes the store is not convenient to your location, or you do not have time to go shopping. Online stores offer the convenience of shopping from home and the added benefit, in many cases, of no additional sales or other taxes. And, with international shipping, many more items are available to shoppers all over the globe via the Internet. For the purposes of this HiMCM problem, we will use an example from the United States.
