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

In the base 10 system, the value of each place is 10 times the value of the place to the immediate right.

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

What symbols can we use to show a number is greater or less than another number? How many different ways can you write a number? What are the differences between standard, word, and expanded form?

After the Game

How does having a good understanding of place value help you compare numbers? When would it be important to know when a number is smaller or larger than another number? What strategies did you use when comparing numbers?
