Session 20: Fraction problems

Introduction  Activity (15 minutes)

"Fraction of Me" Art & Share

Students"The colorteacher ingave each student a paper and asked them to draw a circle on it. The students divided the circle into 8 parts,parts shadingand partsshaded the sections to represent their interestsinterests." (e.g., 3/8 sports, 2/8 music).

Instructions:

1. Each student thinks about their hobbies or interests (e.g., sports, music, reading, video games, etc.).

2. They decide how much time or how interested they are in each activity, and represent that as a fraction out of 8.

For example:

• 2/8 music

• 2/8 reading

• 1/8 video games
  

3. Students colourcolor the slices of the circle based on these fractions using different colourscolors for each interest.

4. The total should always add up to 8/8 (1 whole circle).

Share with a partner or group

Discuss: "How are we similar or different? How does it feel to express yourself through fractions?"

Main Activity (65 minutes)

Fraction Addition and Subtraction Relay (3010 minutes)

Divide students into two teams. In teams, students solve fraction addition/subtraction problems at stations. Each correct answer earns 10 points. The team that solves the problem first will win.

1)

1. Liam drank 2/5 of a bottle of juice in the morning and 1/5 in the afternoon. How much juice did he drink in total?

     How much chocolate does Olivia have left?

Fraction Multiplication with Real-life Scenarios (2515 minutes)

    Divide students into groups of 3.

Each group receives a word problem card with a multiplication of fractions scenario. Examples:

1. A recipe uses 2/3 of a cup of flour. If you make 1/2 of the recipe, how much flour do you need? A garden is 3/5 of a yard wide.
2. A weed grows on 1/4 of it. How much space does the weed take up?
   Sarah jogs 3/4 mile each day. She jogs for 2/3 of a week. How many miles did she jog?

Each group must:

1. 1. Read the problem together
   

2. 2. Identify the fractions and what they represent
   

3. 3. Write a multiplication sentence
   

4. Draw a visual model (area model, bar model, or number line)


4. 5. Solve it and explain the answer in words

Solve It, Show It (30min)

Students work in pairs or small groups.

Each group gets a fraction division word problem card, such as:

1. You have 2/3 liter of juice. Each glass holds 1/6 liter. How many glasses can you pour?
