Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.

The primary purpose of this task is to elicit common misconceptions that arise when students try to model situations with linear functions. This task, being multiple choice, could also serve as a quick assessment to gauge a class' understanding of modeling with linear functions.

Students investigate the ways in which ancient technologies six types of simple machines and combinations are used to construct modern buildings. As they work together to solve a design problem (designing and building a modern structure), they brainstorm ideas, decide on a design, and submit it to a design review before acquiring materials to create it (in this case, a mural depicting it). Emphasis is placed on cooperative, creative teamwork and the steps of the engineering design process.

Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles water, oxygen/carbon dioxide, carbon, nitrogen that exist within the environment.

This task asks students to solve a problem in a context involving constant speed. This task provides a transition from working with ratios involving whole numbers to ratios involving fractions.

This task is designed to help students focus on the whole that a fraction refers to. It helps students to realize that two different fractions can describe the same situation depending on what you choose to be the whole.

This counting activity is done in pairs and helps reinforce the concepts of greater than, less than, and equal to.

This task presents a straight forward question that can be solved using an equation in one variable. The numbers are complicated enough so that it is natural to set up an equation rather than solve the problem in one's head.

High-probability requests are one feasible classroom technique that can be effective in motivating students to engage in assigned classwork (Lee, 2006). The teacher first identifies an academic activity in which the student historically shows a low probability of completing because of non-compliance. The teacher then embeds within that low-probability activity an introductory series of simple, brief 'high-probability' requests or tasks that this same student has an established track record of completing (Belfiore, Basile, & Lee, 2008).

Profile of a Student with This Motivation Problem: The student lacks essential skills required to do the task. Areas of deficit might include basic academic skills, cognitive strategies, and academic-enabler skills. Here are teacher behaviors to help fix this motivation problem.

Although the student has the required skills to complete the assigned work, he or she perceives the ‘effort’ needed to do so to be so great that the student loses motivation. Learn teacher behaviors to fix this motivation problem.

The student is distracted or off-task because classroom instruction and learning activities are not sufficiently reinforcing to hold his or her attention. Learn teacher behaviors to help fix this motivation problem.

The student requires praise, access to rewards, or other reinforcers in the short term as a temporary ‘pay-off’ to encourage her or him to apply greater effort. Learn teacher behaviors to help fix this student motivation problem.

The student has a low sense of self-efficacy in a subject area, activity, or academic task and that lack of confidence reduces the student’s motivation to apply his or her best effort. NOTE: Self-efficacy is the student’s view of his or her own abilities specific to a particular academic area (e.g., mathematics) and should not be confused with self-esteem, which represents the student’s global view of his or her self-worth. Learn teacher behavior to help fix this student motivation problem.

The student appears indifferent or even hostile toward the instructor and thus may lack motivation to follow teacher requests or to produce work. Learn teacher behaviors to help with this student motivation problem.

The purpose of this task is for students to solve problems involving decimals in a context involving a concept that supports financial literacy, namely inflation.

In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of pollution in a lake and the resulting environmental consequences.

The purpose of this task is to engage students in an open-ended modeling task that uses similarity of right triangles, and also requires the use of technology.

This problem uses the same numbers and asks similar mathematical questions as "6.NS The Florist Shop," but that task requires students to apply the concepts of multiples and common multiples in a context.
