The intent of clarifying statements is to provide additional guidance for educators to communicate the intent of the standard to support the future development of curricular resources and assessments aligned to the 2021 math standards.  Clarifying statements can be in the form of succinct sentences or paragraphs that attend to one of four types of clarifications: (1) Student Experiences; (2) Examples; (3) Boundaries; and (4) Connection to Math Practices.

Students conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrots for the materials to be decomposed, and their experiments are carried out in plastic bags filled with dirt. Every few days students remove the carrots from the dirt and weigh them. Depending on the experimental conditions, after a few weeks most of the carrots have decomposed completely.

In this hands-on activity rolling a ball down an incline and having it collide into a cup the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables and review the relationships between these concepts.

This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.

This resource was created by Dylan Huber, in collaboration with Dawn DeTurk, Hannah Blomstedt, and Julie Albrecht, as part of ESU2's Integrating the Arts project. This project is a four year initiative focused on integrating arts into the core curriculum through teacher education, practice, and coaching.

Geospatial data analysis is a growing field in science with practical applications in government and industry.   This problem-based learning module guides learners through exploring the relationship between the amount of trash found relative to the location of waste receptacles in their community. Recording the location of identified items of trash/recyclables and placing them on a map allows students to identify if there is a correlation between the amount of trash and the distance away from waste receptacles.  While this module uses trash, almost any item can be tracked and plotted for analysis.  Some other ideas were: locations of Pokemon in Pokemon Go, animal migration, safety devices, various plant species, texting and driving are just a few examples.

In this task students are asked to write two expressions from verbal descriptions and determine if they are equivalent. The expressions involve both percent and fractions. This task is most appropriate for a classroom discussion since the statement of the problem has some ambiguity.

 This module will introduce students to Intermediate Academic English.  Students will review the learning outcomes for the course and course policies. They will send an email to the instructor, write an introductory paragraph, and begin reviewing verb tenses.

This activity is designed to help students recognize the connections among things like rock identification and map reading with the "story" that these things can tell us in terms of geologic history. Students have already learned about using observation to identify rocks and the principles of interpreting geologic cross-sections. The activity gives students practice in rock ID, topo map reading, geologic map reading and the aspects of geologic time. Students work with rock samples and a geologic map of the Grand Canyon to interpret a history for the area.

After a discussion about what a parachute is and how it works, students create parachutes using different materials that they think will work best. They test their designs, and then contribute to a class discussion (and possible journal writing) to report which paper materials worked best.

Madeline Noonan meets with all of her students individually during writer's workshop. In each conference, she specifically identifies strengths and two goals. Students continue to revise and rewrite throughout the workshop process and build confidence in their writing at the same time.

, We will learn about why flamingos are pink. Students have the opportunity to explore as a class or individually. With suggestions for different age groups. This resource has some activities to engage students with drawing, writing descriptions, or both. 

Students will be able to explain the causes, events, and effects of the Armenian Genocide during World War I. Students will then write a letter advocating their opinion on whether Turkey should or should not assume responsibility for the genocide, citing specific examples from the lesson in their argument.
