Open Middle tasks provide opportunities for student to approach a mathematical task using different strategies and representations. They can be used as a warm-up/closing activity, as a formative assessment, or to facilitate discourse and discussion and get insite into student thinking and problem solving. These tasks provide a great opportunity for student to engage with the Standards for Mathematical Practice.

The purpose of this task is to help solidify students' understanding of signed numbers as points on a number line and to understand the geometric interpretation of adding and subtracting signed numbers.

This problem provides an opportunity for students to reason about ratio and proportion in the realistic context of mixing a fruit drink from concentrate. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support, and links to related problems (Blackcurrantiest is cataloged separately).

The purpose of this task is to extend students' understanding of fraction comparison.

The purpose of this task is to present students with a situation in which they need to divide a whole number by a unit fraction in order to find a solution.

The purpose of this task is for students to find the answer to a question in context that can be represented by fraction multiplication. This task is appropriate for either instruction or assessment depending on how it is used and where students are in their understanding of fraction multiplication.

The purpose of this task is to provide students with a situation in which it is natural for them to divide a unit fraction by a non-zero whole number.

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.

In this activity, students will choose a math topic that they have learned about in the year and plan and film a video about using that topic in a real life way. For example a student could choose fractions and make a video about using a recipe. Students will present their film as part of the assessment.

In this fraction activity students are presented with various situations in which they must determine what fraction of the pizza each person would receive. The activity is built around simple fractions and designed so that students record their results and determine a pattern for dividing fractions among a set of people. In addition to the activity, a solution, teacher resource page, and printable page are provided.

The purpose of this task is to have students add mixed numbers with like denominators. This task illustrates the different kinds of solution approaches students might take to such a task.

In this problem students apply basic proportional reasoning in the context of a pie recipe. Given a recipe for 80 pies, Peter needs to determine whether the ingredients he has on hand are enough to make 2 pies. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, ideas for extension, and printable lists of ingredients (doc).

This task helps students understand that when you multiply by a number you always get a bigger number.

This activity gives students an opportunity to use and develop their visualizing skills in conjunction with the knowledge of fractions. Students are given one large rectangle that is divided into ten smaller quadrilaterals and triangles in which they have to find what fractional part is represented by each of the ten numbered shapes. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support.

In this video segment from Cyberchase, Jackie and Inez figure out how to break an Electro-Root into 2/5, one of the ingredients for the antidote to MotherboardŒë_í_Œ_ virus.
