The goal of this task is to look for structure and identify patterns and then try to find the mathematical explanation for this. This problem examines the ''checkerboard'' pattern of even and odd numbers in a single digit multiplication table.

Whether it's watching TV or playing on a tablet, using tech can be super fun! Often, kids find it hard to transition from an online activity to an offline one. Teach your students a simple routine for how to manage those inevitable digital interruptions that are part of everyone's lives in the digital age.

In this activity students perform a role play of immigrant mothers and daughters arguing over who should get to keep the daughter's wages. This activity is used to teach with the film Heaven Will Protect the Working Girl, but can be completed without the film.

Government agencies frequently contract with nonprofit or for-profit organizations to provide services to improve the well-being of their clients―for example, by reducing recidivism, homelessness, or drug use. Governments have traditionally paid service providers on the basis of the number of clients they treat.
The past decade has seen a number of Pay for Success (PFS) or results-based finance (RBF) programs, in which service providers are paid for their outcomes or results. For example, whereas a government agency contracting with a service provider to reduce recidivism among young men released from prison would traditionally have paid the service provider for the hours spent counseling a client, a PFS contract pays the organization for success in reducing the clients’ rate of recidivism from some baseline.
This handbook is written for government officials considering the adoption of Pay For Success (PFS) programs and for students in public policy and business schools interested in studying outcomes-oriented government contracts for services. Part One introduces concepts necessary to develop and operate a service delivery program and then surveys some of the issues specific to PFS. Part Two presents two detailed case studies and a number of shorter descriptions of PFS programs. Part Three focuses on the components of PFS programs; it also discusses barriers to their development and ways of overcoming them.

This simple conceptual task focuses on what it means for a number to be a solution to an equation, rather than on the process of solving equations.

In this activity, students will learn how water can be polluted by algal blooms. They will grow algae with different concentrations of fertilizer or nutrients and analyze their results as environmental engineers working to protect a local water resource.

This task provides a context where it is appropriate for students to subtract fractions with a common denominator; it could be used for either assessment or instructional purposes.

This task allows students to reason about the relative costs per pound of the two fruits without actually knowing what the costs are. Students who find this difficult may add a scale to the graph and reason about the meanings of the ordered pairs. Comparing the two approaches in a class discussion can be a profitable way to help students make sense of slope.

This art history video dicussion examines Charles Willson Peale's "Staircase Group" (Portrait of Raphaelle Peale and Titian Ramsay Peale), 1795, oil on canvas (Philadelphia Museum of Art).

This word problem requires students to use addition and subtraction and think about money.

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. You can vary friction and the strength of gravity. Use the pendulum to find the value of g on planet X. Notice the anharmonic behavior at large amplitude.

Students investigate the property dependence between liquid and solid interfaces and determine observable differences in how liquids react to different solid surfaces. They compare copper pennies and plastic "coins" as the two test surfaces. Using an eye dropper to deliver various fluids onto the surfaces, students determine the volume and mass of a liquid that can sit on the surface. They use rulers, scales, equations of volume and area, and other methods of approximation and observation, to make their own graphical interpretations of trends. They apply what they learned to design two super-surfaces (from provided surface treatment materials) that arecapable of holding the most liquid by volume and by mass. Cost of materials is a parameter in their design decisions.

People and Organizations examines the historical evolution and current human and organizational contexts in which scientists, engineers and other professionals work. It outlines today's major challenges facing the management profession. The course uses interactive exercises, simulations and problems to develop critical skills in negotiations, teamwork and leadership. Students will be introduced to concepts and tools to analyze work and leadership experiences in optional undergraduate fieldwork projects.

This class provides a historical survey of the ways that people have interacted with their closest animal relatives, for example: hunting, domestication of livestock, exploitation of animal labor, scientific study of animals, display of exotic and performing animals, and pet keeping. Themes include changing ideas about animal agency and intelligence, our moral obligations to animals, and the limits imposed on the use of animals.

How do we sense hunger? How do we sense pain? What causes growth in our bodies? How are we protected from pathogens? The answer to many of these questions involves small polymers of amino acids known as peptides. Peptides are broadly used as signal molecules for intercellular communication in prokaryotes, plants, fungi, and animals. Peptide signals in animals include vast numbers of peptide hormones, growth factors and neuropeptides. In this course, we will learn about molecular bases of peptide signaling. In addition, peptides potentially can be used as potent broad-spectrum antibiotics and hence might define novel therapeutic agents.

This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.

Uses primary sources to explore the impacts World War I had on the struggle for civil rights in Connecticut and America.

Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. Using a paper cut-out shape of a parrot sitting on a wire coat hanger, they learn that their parrot exists in stable equilibrium — it returns to its balancing point after being disturbed. The weight of its tail makes the parrot balance upright. Give the parrot a push, and she knocks off balance, but swings back and forth until coming to rest in balance again.
