Index: 4.1A Grade 4 CPI 3

 

Standard: 4.1 - Number and Numerical Operations

 

Strand: A - Number Sense

 

Cumulative Progress Indicator: 3 - The student will demonstrate a sense of the relative magnitudes of numbers.

 

Grade: 4

 

Sample Activities:

 

·        Students imagine collecting 10,000 of something. They discuss what objects would be reasonable to collect (such as bottle caps, pennies for charity, or pebbles from the beach), how much space this collection might take up, and how much it would weigh?

 

·        Students cut and paste sheets of base-ten graph paper to make models of the different powers of ten: 1, 10, 100, 1000, 10,000.

 

·        Students locate numbers as points on a number line strung across the room, continuing to attach labels as they learn more about numbers. Paper clips or tape are used to fasten equivalent forms of a number to the same point.

 

·        Students estimate and investigate how long a million seconds is using calculators.

 

·        Students write a Logo or BASIC computer program which will count to 100, printing the numbers to the screen as it runs, and timing how long it takes. Then they predict how long it would take the program to count to one thousand, to one hundred thousand, and to one million. They make the required changes to the program and check their predictions.
