Math in My World

Example 1
The O’Dell family went on a whale-watching trip. They learned about different whales. The table shows the lengths of three whales. Order the lengths from least to greatest

Average Lengths of Whales
Whale Length (inches)
Orca Whale ……. 264
Blue Whale …….. 1,128
Humpback Whale ………. 744

One Way Use a place-value chart.
Line up the numbers by their place value from the right. Compare from the left.

Another Way Use a number line.

____ < _____ < ______ The order from least to greatest is ____ inches, ____ inches, and ____ inches.

264< 744 < 1128 The order from least to greatest is 264 inches, 744 inches, and 1128 inches.

Example 2 The table shows the distances whales travel to feed in the summertime. This is called migration. Order these distances from greatest to least

Use a place-value chart to line up the numbers by their place value. Compare from the left.
The greatest number is ____. The second greatest number is ____.
____ > ___ > _____
So, the whales’ migration distances from greatest to least are ____ miles, ___ miles, and ___ miles.

The greatest number is 6,200. The second greatest number is 3,500.
900 > 3,500 > 6,200.
So, the whales’ migration distances from greatest to least are 6,200 miles, 3,500 miles, and 900 miles.
