September 5, 2012 Place Value Eq: What are ways we can compare two whole numbers using <, >, or = ?

Pop quiz Write the value of the underlined digit 478,012 2. 32,817 Write the following numbers in expanded form 204,972 4. 7,821 Write the following number in word form 5. 315,568

Ways to compare When comparing numbers we say that they are… Greater than less than equal to For Example: 5>2 3<10 5+0 = 6-1 Compare these two numbers… 574,882 574,802 >

What if… Check this out! We don’t compare the whole number That can’t be right! 8,472 = 720,400 What digit did I compare? The digit in the hundreds place! 400 = 400

Try these out = > < = < > = > So what’s the plan? Compare the underlined digits 677,548 627,403 836,255 234,578 956,210 572 117,000 241,960 = > < = Compare the whole number 102,542 201,254 827,465 782,654 6,754 6,000+754 321,123 321,113 < > = >

In conclusion We compare numbers using these symbols <,> and = These symbols stand for less than greater than and equal to. We can compare whole numbers and digits.
