Comparing Numbers and Place Value

The video tutorial introduces first graders to the concept of place value and how it determines the worth of a number. It then explains how to compare numbers using the terms greater than, less than, or equal to. Through examples, students learn to compare two-digit numbers by first examining the tens place and then the ones place if necessary. The tutorial concludes with instructions for a Moby Max assignment to practice comparing numbers.

What does place value help us understand about a number?

• The size of the number

• The color of the number

• The shape of the number

• Where a number is and its worth

When comparing numbers, what does it mean if one number is greater than another?

• It has a smaller value

• It is the same value

• It has a larger value

• It is a different color

In the example comparing 26 and 39, why is 26 less than 39?

• Because 39 is a larger number

• Because 26 is a smaller number

• Because 2 is less than 3

• Because 6 is less than 9

What is the first step in comparing two-digit numbers?

• Look at the thousands place

• Look at the hundreds place

• Look at the tens place

• Look at the ones place

When comparing numbers with the same tens, what should you look at next?

• The color of the number

• The size of the number

• The ones place

• The hundreds place

In the example comparing 42 and 45, why is 42 less than 45?

• Because 45 is a larger number

• Because 4 is less than 5

• Because 42 is a smaller number

• Because 2 is less than 5

If two numbers have the same tens, what determines which is greater?

• The color of the number

• The ones place

• The size of the number

• The shape of the number

What should you do if the tens are the same when comparing numbers?

• Look at the color of the number

• Look at the ones place

• Look at the hundreds place

• Look at the thousands place

What do you conclude if two numbers have the same tens and ones?

• The numbers are equal

• The numbers are different

• One number is greater

• One number is less

In the example comparing 67 and 67, what is the result?

• 67 is equal to 67

• 67 is different from 67

• 67 is less than 67

• 67 is greater than 67
