Subtracting Three-Digit Numbers with Confidence

In this video, Mighty Owl takes viewers on a fun math journey at the zoo, using animals to teach subtraction. The video covers solving subtraction problems with three-digit numbers, focusing on place value and regrouping. Examples include a bear's weight loss, hawks' migration distances, and gorilla food consumption. The video emphasizes using tools like base 10 blocks and place value charts to aid understanding and encourages students to choose the best tools for each problem.

What is the first step in solving a subtraction problem?

• Align the numbers randomly

• Subtract the tens place

• Start with the ones place

• Subtract the hundreds place

Why do we start subtraction problems with the ones place?

• It's easier to calculate

• All of the above

• To align the place values correctly

• Because it's a rule

How much weight did the bear lose during hibernation?

• 445 pounds

• None of the above

• 102 pounds

• 547 pounds

What is the result of 547 minus 102?

• 445

• 645

• 455

• 525

What tool is suggested to help visualize subtraction problems?

• Ruler

• Protractor

• Base 10 blocks

• Calculator

What concept is introduced when there aren't enough tens to subtract?

• Regrouping

• Multiplication

• Addition

• Division

How many more miles did the hawks fly in the second week than the first?

• 267 miles

• 441 miles

• 93 miles

• 174 miles

What does the number 93 represent in the context of the hawks' migration?

• Miles flown in the first week

• Total miles flown

• Miles flown in the second week

• Additional miles flown in the second week

How much food did the gorillas eat?

• None of the above

• 674 pounds

• 945 pounds

• 271 pounds

What is the purpose of regrouping in subtraction?

• To make subtraction easier

• To convert hundreds into tens

• To solve addition problems

• Both A and B
