Adding 5
key notes :
| Key Points: |
- Addition means putting things together.
- When we add 5, we increase the number by 5.
- Adding 5 is like counting 5 more.
- Example: If you have 3 apples and get 5 more apples → 3 + 5 = 8.
- We can use fingers, number lines, or objects to add 5.
| 🧮 Examples: |
- 2 + 5 = 7
- 6 + 5 = 11
- 8 + 5 = 13
- 10 + 5 = 15
- 15 + 5 = 20
| 🌈 On a Number Line: |
- Start at a number.
- Jump 5 steps forward.
- The number you land on is the answer.
👉 Example: Start at 4 → jump 5 steps → land on 9. So, 4 + 5 = 9.
| 🎲 Practice: |
- 7 + 5 = ___
- 12 + 5 = ___
- 5 + 5 = ___
- 9 + 5 = ___
- 14 + 5 = ___
| 🖼️ Visual Example (for teaching with pictures): |
- Show 5 extra apples, stars, or blocks being added to a group.
- Use a number line with arrows jumping +5.
Learn with an example
🔷Add. 0 + 5 =
When you add 0 to a number, the number stays the same.
0 + 5 = 5
🔷Add. 10 + 5 =
- You can count on to find 10+5.
- Start at 10 and count on 5 times.
- You end at 15.
- 10 + 5 = 15
_________________________________________________
- You can also think about place value to add.
- 10 + 5 is 1 ten and 5 ones.
| tens | ones |
| 1 | 5 |
- That makes 15.
- 10 + 5 = 15
🔷Add. 4 + 5 =
- You can count on to find 4 + 5.
- It is easier to start with the larger number. So, start at 5. Count on 4 times.
- You end at 9.
- 4+5=9
_____________________________________________
- You can also add using doubles plus one.
- Remember the doubles fact 4 + 4 = 8.
- Notice that 4 + 5 is 1 more. That makes 9.
- 4 + 5 = 9
