Understanding Division with 2-Digit Numbers
Dividing by 2-digit numbers might seem tricky at first, but with practice, you'll become a division superstar!
When we divide larger numbers by 2-digit numbers, we use the same long division steps you already know, but we need to be extra careful with our estimations. Let's break it down into simple steps.
The Division Steps
Step 1: Estimate
Look at the first two digits of the dividend and estimate how many times the divisor fits into it.
Step 2: Multiply
Multiply the divisor by your estimate and write the product below the dividend.
Step 3: Subtract
Subtract the product from the dividend and bring down the next digit.
Step 4: Repeat
Repeat these steps until there are no more digits to bring down.
Let's Practice Together!
Example 1: 432 ÷ 12
Can you solve this division problem? Click to see the steps!
Solution:
1. 12 goes into 43 about 3 times (12 × 3 = 36)
2. 43 - 36 = 7, bring down the 2 to make 72
3. 12 goes into 72 exactly 6 times (12 × 6 = 72)
4. 72 - 72 = 0, so the answer is 36!
432 ÷ 12 = 36
Example 2: 875 ÷ 25
Try this slightly harder problem. Click when you're ready to check!
Solution:
1. 25 goes into 87 about 3 times (25 × 3 = 75)
2. 87 - 75 = 12, bring down the 5 to make 125
3. 25 goes into 125 exactly 5 times (25 × 5 = 125)
4. 125 - 125 = 0, so the answer is 35!
875 ÷ 25 = 35
Parent Tips 🌟
- Use real-world examples: Practice division with everyday items like sharing cookies among friends or dividing money equally.
- Estimation first: Encourage your child to make reasonable estimates before calculating - this builds number sense.
- Celebrate mistakes: Show that wrong estimates are part of learning - we just adjust and try again!
