The purpose of this 3 ACT task is to provide students with an opportunity to problem solve based on a real-world situation. In the task, students are presented with 2 facts related to European Green Crabs and asked to generate their own questions that could be answered using one or both facts. Students then decide on necessary resources for finding the solution and are given time as a group to complete their work. The task concludes by having students examine the information provided in Act III to see if it answers their question. Includes slides to support the implementation of "What's the Problem (3-5)" Math Performance Task with charts, images, etc.

The purpose of this performance task is to engage students in looking for and making use of structure in order to determine the number of stink bugs on a given picture. Students review invasive species and the work of scientists to monitor such creatures, students are provided the problem in the context of supporting invasive species specialists. Working as individuals and then as pairs, students determine the total amount using previous knowledge of patterns such as counting, grouping, or fact families. The task concludes by having student-demonstrated strategies modeled and labeled as a whole group creating strategy posters. Includes slides to support the implementation of "Too Many Stink Bugs (K-2)" Math Performance Task with charts, images, etc.

In this assignment, students are shown real world examples of percentages. They are asked to make calculations and fix calculation mistakes. This assignment will require students to be able to calculate percent increase and percent decrease.

This lesson unit is intended to help teachers assess whether students are able to: identify when two quantities vary in direct proportion to each other; distinguish between direct proportion and other functional relationships; and solve proportionality problems using efficient methods.

Andrea Kowalchik has her students move around the room in pairs while solving proportion problems that are tacked to the walls. This lesson is easy to prepare, fun for students, and gets them working quickly while being active all at the same time.

This lesson is about ratios and proportions using candy boxes as well as a recipe for making candy as situations to be considered. It addresses many Mathematical Reasoning standards and asks students to: Use models to understand fractions and to solve ratio problems; think about a ratio as part/part model and to think about the pattern growing in equal groups or a unit composed of the sum of the parts; find a scale factor and apply it to a ratio. (5th Grade Math)

In this lesson, students are introduced to rate in the context of music. They will explore beats per minute and compare rates using mathematical representations including graphs and double number lines.Key ConceptsBeats per minute is a rate. Musicians often count the number of beats per measure to determine the tempo of a song. A fast tempo produces music that seems to be racing, whereas a slow tempo results in music that is more relaxing. When graphed, sets with more beats per minute have smaller intervals on the double number line and steeper lines on the graph.Goals and Learning ObjectivesInvestigate rate in music.Find beats per minute by counting beats in music.Represent beats per minute on a double number line and a graph.

From politics to cookery, ratios, proportions and percentages are part of everyday life. This unit is designed to help you become more familiar with how figures can be manipulated, then you can check whether that discount really is as big as they claim!

Welcome to the UnboundEd Mathematics Guide series! These guides are designed to explain what new, high standards for mathematics say about what students should learn in each grade, and what they mean for curriculum and instruction. This guide, the first for Grade 7, includes three parts. The first part gives a “tour” of the standards for Ratios & Proportional Relationships using freely available online resources that you can use or adapt for your class. The second part shows how Ratios & Proportional Relationships relate to other concepts in Grade 7. And the third part explains where Ratios & Proportional Relationships are situated in the progression of learning from Grades 3-8.

This lesson unit is intended to help teachers assess how well students are able to: translate between decimal and fraction notation, particularly when the decimals are repeating; create and solve simple linear equations to find the fractional equivalent of a repeating decimal; and understand the effect of multiplying a decimal by a power of 10.

This task provides a context for indentifying different ways of representing half of a rectangle.

This lesson unit is intended to help teachers assess how well students are able to solve a real-world modeling problem. There are several correct approaches to the problem, including some that involve proportional relationships.

This course introduces students to the types of writing they will encounter in business, industry, the academic world and government. It examines the rhetorical nature of writing and asks students to think critically about content, audience, argument and structure. Students will learn how to effectively design documents, present instructions, create proposals and produce technical reports.

Course Outcomes:
1. Analyze the rhetorical needs (the needs of the audience in relationship to the assignment) for college-level evidence-based technical writing assignments.
2. Apply appropriate levels of critical thinking strategies (knowledge, comprehension, application, analysis, synthesis, evaluation) in their written assignments, with an emphasis on technical, evidence-based analysis, reporting, application, and evaluation.
3. Implement appropriate rhetorical elements and organization (executive summary, introduction, thesis, development and research-based support, visual evidence, conclusion, etc.) in their written assignments, with an emphasis on technical evidence-based analysis, reporting, and evaluation assignments.
4. Locate, evaluate, and integrate high-quality information and opinion appropriate for technical evidence-based assignments.
5. Craft sentences and paragraphs that communicate their ideas clearly and effectively using words, sentence patterns, and writing conventions at a high college level to make their writing clear, credible, and precise.

In this task students see different ways of partitioning a circle and a rectangle into two or more equal shares.
