Subtracting 7

key notes :

🔢 What is Subtraction?

Subtraction means taking away.
➡️ When we subtract 7, we take away 7 objects.
🎈 Example: 10 − 7 = 3

🍎 Subtracting 7 Using Objects

Children can use:
🍏 Apples
🧸 Toys
⭐ Stars
Draw 7 items and cross them out!
✔️ Example:
🍎🍎🍎🍎🍎🍎🍎🍎🍎🍎
Cross out 7 → Remaining = 3

🧠 Think of It as Counting Back

When subtracting 7, count back 7 numbers.
Example:
15 → 14 → 13 → 12 → 11 → 10 → 9 → 8
So, 15 − 7 = 8 🎉

🎨 Use Number Line

A number line helps students jump back 7 steps.
Example: Start at 12, jump back 7 🦘
12 → 11 → 10 → 9 → 8 → 7 → 6 → 5
So, 12 − 7 = 5 ⭐

🧮 Facts to Remember

📌 Subtracting 7 always makes the number smaller by 7
📌 You cannot subtract 7 from a number smaller than 7 (in Grade 1 tasks)

Learn with an example

✈️Subtract.15 – 7 =

  • You can count back to find 15 – 7. Start at 15 and count back 7 times.
  • You end at 8.
  • 15 – 7 = 8

__________________________________________________

  • You can also use 10 to find 15 – 7.
  • Start at 15. Subtract 5 to get to 10. Then subtract 2 more. That way, you subtract 7 in all.
  • You end at 8.
  • 15 – 7 = 8

✈️Subtract. 8 – 7 =

  • You can count on to find 8 – 7. Start at 7. Count on until you reach 8.
  • You counted on 1 time.
  • 8 – 7 = 1

✈️Subtract. 7 – 7 =

  • When you subtract a number from itself, the answer is zero.
  • 7 – 7 = 0
  • You can count back to show this. Start at 7 and count back 7 times.
  • You end at 0.
  • 7 – 7 = 0
