Summary:
This unit will focus on the understanding of fractions and applying them to real life situations. The students will engage in numerous hands-on activities that explain various strategies that help solve fraction problems. Throughout this unit, the students will use manipulatives that they will create to develop a strong background of fractions.

Stage 1: Identify Desired Results

State:	KS
Title:	Mathematics - Number and Computation
Standard(s):	Uses equivalent representations for the same whole number, decimals, and simple fractions (thirds, fourths, tenths, and hundredths.) Uses appropriate representations of whole numbers, decimals and fractions to formulate and solve real-world problems. Uses a variety of computational methods including mental mathematics, paper and pencil, concrete materials and calculators and computers to estimate quantities involving rational whole numbers, fractions, decimals, and money.

Understandings:
user	Fractions represent division and equal parts of a whole. Fractions help solve real-life situations. Fractions can be represented as decimals and percents.

Essential Questions:
User	* How are fractions important in daily life? * Do adults in any occupations use fractions as part of their job? * What is the relationship between fractions, percentage and decimals?

Knowledge and Skills:

K
How to complete various operations of with fractions.
The relationship between a fraction and whole number.


S
*Develop fractions circles to utilize when completing the operations of fractions.

Notes:

Student Directions:
You have been hired as a nutritionist for Cheney USD 268 Food Services. Because the number of students eating changes from day to day, your job is to take their recipes and convert the amounts of ingredients to match the number of students eating. Some may need to be doubled or tripled while others may need to be reduced by halves and quarters.
You will also need to convert the fractions in your recipe to decimals.
Finally create a pie chart of all the ingredients in your recipe to show the percent of each ingredient.

Your conversions should be accurate and complete.

Other assessment evidence to be collected:

Stage 3: Plan Learning Experiences and Instruction

Learning Activities:

W
Pre-test on fractions, percent and decimals.

H
Each student will receive a cookie and the recipe that will make 100 cookies. They will then be asked what they need to do if they would like to make about two dozen cookies instead.

E
Textbook activities over fractions, decimals, and percentage.
Students will use manipulatives as they work with fractions.
Students will make Fraction Sticks -- Directions???
Whenever student papers are returned, they will figure their own percent on the activity.
Students will brainstorm for examples of fractions in real life and bring examples.
Students will practice for their final assessment by bringing their favorite cookie recipe from home. They will need to double and triple it as well as reduce it by halves and quarters. They will convert the fractions to decimals. They will also create a pie chart showing the percentage of each ingredient in the recipe. Finally in pairs, they combine the quantities of each ingredient from each recipe into a single shopping list.

R
Students will review the results of their manipulation of the own recipe (see above) to check for accuracy.

E
Students will each make a recipe to feed a given amount of people. They will be required to do the calculations in order to make enough food to feed all of their guest.

Post-test on fractions, percent and decimals.
