Instructions

Play through this interactive game to learn about Compare Two Multi-Digit Whole Numbers. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

To read numerals between 1,000 and 1,000,000 each sequence of three digits made by commas is read as hundreds, tens, ones followed by the name of the appropriate base-thousand unit (thousand, million, billion, etc.) ex. 365,000 is read as “three hundred sixty five thousand).

Compare two numbers by closely looking at place value, (Which number is greater 3,245 or 3,425? 3,425 because the digit in the thousands place is the same but the number in the hundreds place is greater).

Show comparisons using >, < and = where > is used to denote the value on the left is greater and < to show the value on the right is greater.

Convert between expanded form, number names and numerals. Write in written form.

After converting between expanded form, number names and numerals, compare numbers based on place value.

Discussion Questions

Before the Game

In the number 785, what number is in the hundreds place? Can you write the number 785 in expanded notation? How do you know what place value a number is in? Using the digits 3, 5, and 1, create three different numbers and then order them greatest to least.

After the Game

In this game it had you choose which crab had the higher value - did this illustration help you to see the importance of place value? What did you learn about place value? What are some ways to help you remember which way the > or < goes to show less than or more than? Look at the numbers 785 and 758 - why is 785 greater than 758?
