**Introduction:** A Fraction Finding Mission project is an individual activity
that stresses problem solving and critical thinking as applied to operations
between rational numbers.

**Timing:** This activity requires 90 minutes of class time to
complete. Break it up over two,
maybe three periods. Some of the
project can be assigned for homework. Getting the math component done in class will allow students to focus on
the creative component at home and will reduce the chance that students will
get too far off base with the mathematical side of the project.

**Group Size:** Individual

**Learning Objectives:** The objective of this activity is to:

a) Review rational numbers and operations between various forms of rational numbers (mixed fractions, improper fractions, and normal fractions)

b) Develop problem solving and critical thinking skills

c) Integrate a creative component into a traditional math lesson

**Guiding Questions:** How can you use various forms of rational numbers be
combined to create a sequence of integers?

**Materials:** Colored poster paper, markers, scissors, and other random
art supplies. Photocopy enough activity sheets for each student.

**Procedures:**

Read through the opening sections as a class. This is an individual activity, so students may have varying levels of competence with operations between rational numbers, so they may need different amounts of support. The multiplication and division component of lab is challenging, so take your time explaining them and do multiple examples.

This activity requires students to create the integers between -10 and 10 using two rational numbers and an operation. Negative and positive rational numbers, each of the four operations (+, -, ¸, ·), and the different types of rational numbers (regular fractions, improper fractions and mixed fractions) must be used equally.

The art aspect of this project is pretty wide open. Their original rational numbers and the operation just need to be presented in some creative way on the poster. Students should focus on getting their rational numbers and operations completed before focusing on the design component. Students can present their A Fraction Finding Mission project in a variety of ways. I have included the number line and bingo board options in case students struggle with a create way to present their results.

Make sure students record their original rational numbers, operations, and work in the table provided. This is where their fractions will actually be graded for correctness. Their poster will only be assessed for creativity and neatness.

Make sure student understand the use of the rubric and know that they must score themselves before the project is turned it. The extra point is given with the idea that if anyone matches my score, they must of used the rubric properly. The same goes for taking the point. If they over-scored themselves by four points, they probably did not follow the rubric.

**Assessment:** A Fraction Finding Mission project should be graded based on
the rubric included in the activity sheet

**Answer Key:** Each student’s Fraction Finding Mission project will be
different, so an answer key would be of no use.
