Day 12: Subtraction Safari! ➖

Foundation Stage Mathematics | Apex Institute of Maths and Sciences

🎯 1. Concept: Taking Things Away

Welcome to Day 12! Yesterday we added things together to make our numbers bigger. Today, we are learning about Subtraction.

Subtraction means “taking away.” When we subtract, our final number gets smaller!

🍎🍎🍎🍎 ➖ 🍎🍎 🟰 🍎🍎 4 Apples MINUS 2 Apples EQUALS 2 Apples!

💡 2. The Magic Signs

To do subtraction, you need to know these two signs:

  • ➖ The Minus Sign: This straight little line means “take away” or “subtract.”
  • 🟰 The Equals Sign: This means “is the same as” or “how many are left.”
⭐⭐⭐⭐⭐ ➖ ⭐ 🟰 ⭐⭐⭐⭐ 5 Stars – 1 Star = 4 Stars

🌍 3. Math in Our Daily Life

We use subtraction every time we eat snacks or spend money!

Scenario 1: Eating Cookies! 🍪 If your mom gives you 5 cookies, and you eat 2 of them, how many are left? You just did subtraction! (5 – 2 = 3 cookies left).

Scenario 2: Popping Balloons! 🎈 You have 10 balloons at a birthday party. Oh no, 1 balloon pops! Now you have 9 balloons. (10 – 1 = 9).

📝 4. Home Practice (Fun Tasks)

Parents, please guide your child with these taking-away games!

  • Task A: The Toy Box Takedown: Put 10 small toys in a line. Close your eyes while your parent takes 3 toys away. Open your eyes, count what is left, and say the math sentence out loud! (“10 minus 3 equals 7!”)
  • Task B: Snack Time Math: At snack time, count out 8 grapes, crackers, or chips. Every time you eat one, say the new subtraction sentence. (e.g., “8 minus 1 equals 7!”)

Are you a Subtraction Master? Take this quiz to find out! Select your answers and click submit to check your score.

Easy
1. What does the minus sign (➖) tell us to do?
Solution: The minus sign means subtraction, which is taking things away!
Easy
2. You have 5 fingers on one hand. If you hide 1 finger, how many are left? (5 – 1 = ?)
Solution: 5 take away 1 leaves 4 fingers standing!
Easy
3. What happens if you have 3 cookies and you eat ALL 3 cookies? (3 – 3 = ?)
Solution: If you take away the exact same number you started with, you have zero (0) left!
Easy
4. Solve this math sentence: 4 ➖ 2 🟰 ?
Solution: Start with 4, take away 2. You have 2 left over.
Medium
5. Use your “Friends of 10”! If you have 10 blocks, and take away 2, how many are left? (10 – 2 = ?)
Solution: Because 8 and 2 make 10, taking 2 away from 10 leaves exactly 8.
Medium
6. Solve this math sentence: 7 ➖ 3 🟰 ?
Solution: Count backward 3 times from 7: 6… 5… 4!
Medium
7. You see 8 birds sitting on a tree. 1 bird flies away. How many birds are left on the tree?
Solution: 8 – 1 = 7. Taking away 1 is just counting backward by one number!
Medium
8. What happens if you take away ZERO? What is 6 ➖ 0 🟰 ?
Solution: Zero means “nothing”. If you have 6 and take away nothing, you still have 6!
Hard
9. You have 9 toy cars. You give 4 of them to your friend. How many toy cars do you have left?
Solution: 9 – 4 = 5. (You can check by adding them back: 5 + 4 = 9!).
Hard
10. Brain Teaser: If you know that 10 ➖ 4 🟰 6… what is 10 ➖ 6 🟰 ?
Solution: The numbers are all connected! If 10 take away 4 is 6, then 10 take away 6 must be 4!
