Comparing Numbers in the Millions

The video tutorial revisits the concept of comparing numbers, initially taught in first grade using the 'hungry alligator' game. It explains how to compare larger numbers, such as those in the millions, by examining digits in higher place values. The tutorial outlines a step-by-step process to determine which number is greater, less, or equal by comparing digits from the highest place value downwards. An example is provided to illustrate the method, emphasizing the importance of careful examination of each digit. The video concludes by discussing the outcome if all digits are the same, resulting in an equal sign.

What game was used to teach comparing numbers in first grade?

• Hungry Alligator

• Hungry Tiger

• Hungry Hippo

• Hungry Lion

When comparing large numbers, what is the first step?

• Check the ones place

• Check the highest place value

• Check the tens place

• Check the hundreds place

Why can't we just look at large numbers and immediately know which is greater?

• Because we might make mistakes

• Because they are too big

• Because they are confusing

• Because they have more digits

What should you do if the digits in the highest place value are the same?

• Add the digits together

• Stop comparing

• Subtract the digits

• Move to the next highest place value

What is the second step in comparing large numbers?

• Compare digits until one is different

• Check the highest place value

• Check the ones place

• Compare the tens place

In the example, what place value was different between the two numbers?

• Thousands

• Millions

• Hundreds

• Ten thousands

What sign is used when one number is greater than another?

• Less than

• Greater than

• Equal to

• Not equal to

What is the correct comparison for 1,256,031 and 1,254,904?

• 1,256,031 = 1,254,904

• 1,256,031 > 1,254,904

• 1,256,031 < 1,254,904

• 1,256,031 <= 1,254,904

What is the place value of the digit '6' in the number 1,256,031?

• Hundreds

• Thousands

• Ten thousands

• Millions

What happens if all digits in the compared numbers are the same?

• Use the equal to sign

• Use the less than sign

• Use the greater than sign

• Use no sign
