Jaci and Emma are playing a game on their computer where a player earns points.
At the end of the first round: Jaci has seventy-four thousand, two hundred sixteen points. Emma has 70,000 + 4,000 + 100 + 80 + 9 points.
At the end of the second round: Jaci has 52,000 + 200 + 30 + 1 points. Emma has fifty-two thousand, sixty-eight points.
At the end of the third round: Jaci has 62 thousand, 9 hundred seventy-nine points. Emma has sixty-two thousand, nine hundred eighty-four points.
Jaci and Emma organize their points information together and use the greater than, less than, or equal sign to compare who made the most points in each round. How could Jaci and Emma organize their information and include the correct sign? Who made the most points in each round? Show all your mathematical thinking.
Whole Number and Decimal Place Value Unit
The Whole Number and Decimal Place Value
Unit involves understanding and representing the relative position,
magnitude and relationships within the numeration system in order to
answer questions such as:
How can you use the additive property of place value to decompose this number?
