Elena collected 431 bottles for recycling. Pete collected 227 fewer bottles than Elena. How many bottles did Pete collect?

What do you need to find?
Explanation:
Elena collected 431 bottles for recycling.
Pete collected 227 fewer bottles than Elena.
Number of bottles collected by Pete
431 – 227 = 204

Circle the numbers you need to use. Explanation:
Numbers that are used to circle are Elena collected bottles and Pete collected bottles.

Combine place values to find the difference.

A. Subtract. 431 – 227
Estimate. 400 – 200 = ________
STEP 1: Look at the ones place. Since 7 > 1, combine place values. Combine the tens and ones places. There are 31 ones and 27 ones. Subtract the ones. Write 0 for the tens. Estimate. 400 – 200 = 200

STEP 2:
Subtract the hundreds.
So, Pete collected _________ bottles.
Since ___________ is close to the estimate of _________, the answer is reasonable. So, Pete collected 204 bottles.
Since 204 is close to the estimate of 200, the answer is reasonable.
Explanation:
To find a value that is close enough to the right answer,
usually with some thought or calculation involved. is called estimate.
So, the estimate of 204 is 200.

Regrouping the numbers for subtracting the higher number from smaller number

B. Subtract. 500 – 173
Estimate. 500 – 175 = ___________
STEP 1:
Look at the ones and tens places. Since 3 > 0 and 7 > 0, combine the hundreds and tens. There are 50 tens. Regroup 50 tens as 49 tens 10 ones. Subtract the ones. STEP 2:
Subtract the tens. So, 500 – 173 __________.
500 – 173 = 327

Explain why you combined hundreds and tens.
Yes, we need to regroup.
Explanation:
Sometimes we need to regroup the hundreds and the tens.
For example,
352 – 185 = 167
Place value disks can help us figure it out.
Subtract ones from ones first.
But we can’t take away five ones,
We only have 2 ones,
So, let’s regroup.

Problem Solving

Use Tools Use the table for 13-18. Question 13.
The table shows the heights of some roller coasters in the United States. How much taller is Kingda Ka than Titan?
211 feet
Explanation:
Height of Kingda ka = 456
Height of Titan = 245
The difference between both
456 – 245 = 211

Question 14.
How many feet shorter is Intimidator 305 than Top Thrill Dragster?
115 feet
Explanation:
Height of Top Thrill Dragster = 420

Explanation:
Height of Titan = 245
Combine both the heights
245 + 175 = 420
So, Top Thrill Dragster is taller than Titan.

Question 16.
Multi-Step How much shorter is Top Thrill Dragster than the heights of Titan and Kingda Ka together?
281 feet
Explanation:
Height of Titan  = 245

If the roller coaster is less then 195, then Intimidator is shorter.
500 – 195 = 305

Question 18.
Multi-Step Pose a Problem Look back at Problem 17. Write and solve a similar problem by using different numbers.
What if a roller coaster was 500 feet tall? Which roller coaster would be 255 feet shorter?
Explanation:
Suppose the height of roller coaster = 500
If the roller coaster is less then 255, then Titan is shorter.
500 – 255= 245 feet
