## Fraction Food Frenzy (Middle School)

### Amy Gunn

#### Description

This lesson is an introductory lesson for adding fractions with like denominators. It allows for illustrations and simple problem solving.

#### Objectives

The student knows the effects of the four basic operations on whole numbers, fractions, mixed numbers, and decimals.

The student uses models or pictures to show the effects of addition, subtraction, multiplication, and division, on whole numbers, decimals, fractions, and mixed numbers.

#### Materials

-Worksheets included in Associated File

#### Preparations

1. Print worksheets found in Associated File.
2. Copy worksheets for students
3. Decide whether to make an overhead of Worksheets 1 and 2 to use when doing examples or to use the chalkboard.

#### Procedures

Prior Knowledge: Writing and Reading Fractions written in words and expressed as numbers and adding simple fractions. Look at worksheets found in the Associated File before reviewing the following procedures:

Step 1: Go over example on the teacher and student work pages with students explaining that an illustration is a drawing. Make sure to tell students that they must use food items or related objects (plates, cups, bowls, cookie sheets, etc.). Review with students that when fractions have the same denominators, only the numerators are added. (Teacher Note: All of the fractions worked with today will use like denominators. This lesson can be adapted to work with mixed number addition when like denominators are used also.)

Step 2: Take a suggestion from the class as to what food item they would like to illustrate on the first problem. Then work it with them. The teacher may choose to make an overhead copy of the worksheet or simply complete the problem on the board.

Step 3: Have the students complete the second problem individually. Then ask 2-3 students to come to the board (or overhead) and demonstrate how they completed their problems.

Step 4: Have students complete the rest of the problems. Travel around the room observing student work, answering questions, and making comments as necessary. Be sure to praise creativity and correct answers. This is a formative assessment worksheet. It should be used for a teaching tool only and not graded.

Step 5: Review correct answers and ask for questions from students. Reteach and review as necessary prior to completing the next worksheet.

Step 6: On worksheet 2, complete word problem #1 as an example for students. Have students complete problem two on their own and then stop to review the correct answer and illustrations used to express the answer. Then have students complete the rest of worksheet 2. This worksheet is also for further skill development and practice and is not intended to be graded.

Step 7: After reviewing and reteaching worksheet 2 (which includes skills from worksheet 1) as necessary, have students complete worksheet 3 individually. Worksheet 3 can be used as a graded assignment.

#### Assessments

The worksheets included allow for percent of accuracy to be noted with the Sunshine State Standard at the bottom of the page. Worksheet 1 and 2 are designed to be used as formative assessment and worksheet 3 can be used summatively.
