# Session 5: Subtraction
**Session Title** **Subtraction**
Objective - Understand subtraction through situation-based and real-life examples. - Apply subtraction to everyday tasks and scenarios. - Solve subtraction problems using fun, interactive activities.
Concept Subtraction is used in real-life situations to take away or find the difference between quantities. It is useful when giving change, removing objects, or finding how much is left.
Materials Required 1. Board & Chalk, Counters(small physical objects used to help students visualize and solve math problems.They can be anything like:Colored chips,Bottle caps,Beads,Pebbles,Coins,Buttons), 2. Dice 3. Role-play props (toys, food items, play money) 4. Chart paper 5. Number line
Methodology Activity-based Learning: Games and acting out real-life scenarios. Experiential Learning: Practicing subtraction through relevant daily experiences.
Session Duration 90 Minutes
### Intro Activity (15 minutes): **Market Math** Set up a pretend market. Each student gets some fake money. Items have price tags. Students buy items and calculate how much money they have left using subtraction. ### Main Activity(65 minutes): **Objective:** Build subtraction understanding through realistic examples. **Subtraction Scenes (10 minutes)** **Ask**: 1. A child has 10 cookies and eats 3. How many are left? 2. A shop has 15 pencils, and 6 are sold. How many remain? 3. A basket had 8 apples. 5 are given away. How many are left? **Class discusses and writes subtraction sentences.** **Substraction Treasure Hunt (20 minutes)** 1\. Hide numbers around the room. 2\. In teams, students pick two numbers, subtract the smaller from the larger. 3\. Write a subtraction sentence and run to post it on the answer chart. 4\. The team with the most accurate sentences wins. **Time to Solve (25 Minutes)** **Subtraction**: 1. Picture-based subtraction 2. This involves showing pictures (like apples, animals, or toys) and asking students to count and subtract by visually removing some. **Example:** There are 7 apples in a picture. Then 3 are crossed out. Question: “How many apples are left?” Answer: 7 - 3 = 4 **2. Real-life word problems** These help children understand how subtraction is used in everyday life. **Example 1:** "There were 12 birds. 4 flew away. How many are left?" Children need to subtract 4 from 12: 12 - 4 = 8 birds are left **Example 2:** "You had 10 candies. Gave 3 to your friend. How many do you have now?" Subtract the given candies: 10 - 3 = 7 candies left **3. Fill in the blanks** These help kids work backwards in a subtraction equation. **Example:** \_\_\_ – 3 = 6 **Ask**: “What number minus 3 equals 6?” **Answer:** 9, because 9 - 3 = 6 **Fill-in-the-Blank Questions** 1\. \_\_\_ – 6 = 9 2\. \_\_\_ – 4 = 7 3\. 10 – \_\_\_ = 6 4\. \_\_\_ – 6 = 3 5\. 8 – \_\_\_ = 2 6\. \_\_\_ – 15 = 4 7\. 15 – \_\_\_ = 10 8\. \_\_\_ – 7 = 2 9\. 9 – \_\_\_ = 3 10\. \_\_\_ – 15 = 6 ### Review Questions(10 minutes): **Ask**: 1. When did you use subtraction today? 2. Can subtraction mean 'how many more'? 3. How did role-play help you understand subtraction? ### Follow up Tasks(10 minutes): **Homework:** 1. Think of 3 real-life situations where subtraction was used today. 2. Write the subtraction sentence for each. 3. Ask a family member a subtraction problem and explain how they solved it ### Expected Learning Outcome: **Knowledge building:** - Concept of subtraction through everyday context. - Visual and situational understanding of subtraction. **Skill Building:** - Logical reasoning - Visual learning through role play - Confidence in applying math to real life
