Addition by Splitting
- Split two-digit numbers into tens and ones.
- In the above example, we split the number 23 as: 20 + 3.
- And split the number 14 as 10 + 4.
- Then add 1-digit numbers: 3 + 4 = 7.
- Then it is easy to add: 20 + 10 + 7 = 37
What is a Quick Mental Math Addition Strategies Tens Fact?
Quick Mental Math Addition Strategies With Tens Two children are napping.” Make Ten facts are pairs of numbers that equal 10. Being able to instantly recognize combinations that make 10
for example, 3 + 7 = 10— helps when adding 30 + 70 = 100 or 43 + 7 = 50. Add Ten facts (10 + 3, 7 + 10) apply when 10 is added to a single-digit number.
- Adding Tens to a Two-Digit Number:
- Strategy: When adding a multiple of ten to a two-digit number, simply increase the tens digit by the appropriate number of tens.
- Example: 47 + 30
- Add 3 tens (30) to 4 tens (40), resulting in 7 tens (70).
- Combine with the units place: 70 + 7 = 77.
- Adding Tens to a Three-Digit Number:
- Strategy: Similar to the previous technique, adding tens to a three-digit number involves adjusting the hundreds and tens digits.
- Example: 248 + 50
- Add 5 tens (50) to 4 tens (40), resulting in 9 tens (90).
- Keep the hundreds place as is: 200.
- Combine with the units place: 200 + 90 + 8 = 298.
- Adding Two Numbers with Tens in Different Places:
- Strategy: When adding two numbers with tens in different places, start by adding the tens separately, and then add the units.
- Example: 76 + 35
- Add the tens: 70 (from 76) + 30 (from 35) = 100.
- Add the units: 6 + 5 = 11.
- Combine both results: 100 + 11 = 111.
- Carrying Over When Necessary:
- Strategy: When the sum of units exceeds ten, carry over the extra to the tens place.
- Example: 58 + 47
- Add the units: 8 + 7 = 15. Carry over 1 to the tens.
- Add the tens: 50 + 40 + 1 (carried over) = 91.
- Combine both results: 91 + 5 (carried over) = 96.
- Adding Multiple Numbers with Tens:
- Strategy: Add the tens together, then add the remaining digits one by one.
- Example: 30 + 40 + 20 + 50
- Add the tens: 30 + 40 + 20 + 50 = 140.
- Add the units: 0 + 0 + 0 + 0 = 0.
- Combine both results: 140 + 0 = 140.
