Add one-digit numbers
key notes :
โ Addition Means Putting Together
When we add, we join two groups to find the total.
Example: 3 + 2 = 5
๐งธโ๐งธ๐งธ = ๐5
๐ข Add One-Digit Numbers (0โ9)
Students practice adding any two numbers between 0 and 9.
Examples:
6 + 3, 4 + 5, 7 + 1
๐ + ๐๐๐๐๐๐๐ = ๐
๐๏ธ Use Fingers, Objects or Pictures
To help understand, children can use:
๐ Fingers
๐ Objects
๐ Pictures
Example: Show 4 apples and add 3 more ๐๐๐๐ + ๐๐๐
โก๏ธ Count On Strategy
Start with the bigger number and count forward.
Example: 5 + 3
Start at 5 โก๏ธ say โ6, 7, 8โ
So, 5 + 3 = 8 ๐
โ๏ธ Adding Zero
When you add 0, the number stays the same.
Example: 7 + 0 = 7
๐โ0 = ๐
๐ง Addition Facts to Memorize
Students should remember basic facts like:
3 + 3 = 6
4 + 5 = 9
2 + 7 = 9
๐ฏ Helps to add faster!
๐ฏ Number Bonds Help
Numbers that make the same total.
Example:
To make 10 โ 1+9, 2+8, 3+7, 4+6, 5+5
๐ก Number bonds help with quick answers.
๐ Addition is Commutative
Switching numbers doesnโt change the answer.
Example:
2 + 5 = 7
5 + 2 = 7
๐ Same total!
๐ Use Simple Word Problems
Example:
Ravi has 3 balls ๐พ and gets 2 more.
How many balls now?
3 + 2 = 5 ๐
๐ Practice Makes You Faster
More practice = faster adding!
Keep solving fun sums, games and puzzles ๐ฎ๐งฉ
Learn with an example
Add 2 + 7 =
Adding zero does not change a number.
Add:
0 + 4 = 4
The sum is 4.
Add: 8 + 9 =
You can count up to add. It is easier to start with the larger number. Start from 9 and count up 8:
9, 10, 11, 12, 13, 14, 15, 16, 17
8 + 9 = 17
The sum is 17.
Add: 9 + 8 =
You can count up to add. Start from 9 and count up 8:
9, 10, 11, 12, 13, 14, 15, 16, 17
