This lesson is designed to help students develop strategies for solving optimization problems. Such problems typically involve using limited resources to greatest effect, as in, for example, the allocation of time and materials to maximize profit.
Before the lesson, students attempt the problem individually. You then review their work and formulate questions for students to answer in order to improve their solutions.At the start of the lesson, students work alone answering your questions.Students are then grouped and engage in a collaborative discussion of the same task. In the same small groups, students are given sample solutions to comment on and evaluate.In a whole-class discussion, students explain and compare solution strategies seen and used.Finally, students revise their individual solutions and comment on what they have learned.
Materials required
Each individual student will need a copy of the  task, some plain paper, a calculator, and a copy of the How Did You Work? questionnaire.Each small group of students will need copies of the Sample Responses to Discuss.Graph paper should be kept in reserve and used only when necessary or requested.
Time needed
Approximately 15 minutes before the lesson, a 1-hour lesson, and 10 minutes in a follow-up lesson.

This resource includes both the external anatomy and internal anatomy. The virtual lab components include the procedure, external anatomy including formative assessment interactives, and internal anatomy including formative assessment interactives.
The lab is presented sequentially and thoroughly. Students may repeat parts of the lab as many times as needed to review information or steps they have completed. This lab includes audio, text, interactive steps, and a journal activity. The students will need to follow the directions to complete all of the steps.
The lab has text, audio so that the text can be read, video, and interactive activities.

This applet allows the user to investigate the mean, median, and box-and-whisker plot for a set of data that they create. The data set may contain up to 15 integers, each with a value from 0 to 100.

This applet allows the user to select the number and height of plants or to name a different item data have been collected about to experiment with to find the total height, mean, median, mode, range, variance, and deviation.

This Mayo Clinic website lists 45 medical professions for students to explore. By clicking on each profession, students can watch a video highlighting the responsibilities and importance of that job or look at a picture illustrating the job in action. Students can also read the job description, learn about the work environment and career outlook, and delve into higher education requirements. This medical career exploration improves students’ knowledge of career options and encourages students to set educational goals. This goal can be measured by the accompanying worksheet linked in WISELearn. Students will identify and explain three medical careers of interest. Then they will organize all 45 medical professions into categories based on education length and career pathway.

This lesson could be used in a High School Geometry course when students are working with similar triangles and the fundamental theorem of similarity. Students will be challenged to solve a non-routine problem by applying a geometric concept in a modeling situation. The lesson plan is extensive including samples of student work and possible misconceptions. The activity can be adapted to meet the needs of your students.

This resource is an interactive student activity where students will create a budget and describe steps they can save to minimize spending.  This activity provides step-by-step information and examples to create a student budget.  Students are also given the opportunity to use Excel (Google Sheets) to create their budget and analyze it through the creation of charts and graphs.

Students will have an overview of various ways to multiply 2, 3, and 4 digit numbers, including the place value model, the use of the distributive property, as well as the area model. Following instruction, several opportunities for practice are available.

In this episode of NJEA’s Classroom Close-up, Fort Lee’s School No. 1 is using music to extend concentration among general and special education students in kindergarten through second grade. In addition, working one-on-one using dials to analyze a student’s response to various genres of music, educators are studying the impact the music has on a student’s ability to focus, which will help to improve and enhance student learning.

This activity serves to get students active and to teach them to work with all students in their class to acieve group success.
