Index: 4.1A Grade 6 CPI 3

 

Standard: 4.1 - Number and Numerical Operations

 

Strand: C - Estimation

 

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

 

Grade: 6

 

Sample Activities:

 

·        Students challenge each other to find target numbers on a number line. First one student asks another to find 3.2. The second target number then must be between 0 and 3.2, say 1.74. The third must then be between 0 and 1.74 and so on.

 

·        Students use their calculators to explore the types of decimal expansions for common fractions. They discover that some such decimals terminate, some repeat, and some appear to do neither. (Actually, if the calculators could exhibit more digits, each such decimal would either terminate or repeat.)

 

·        Students use calculators to come as close as they can to an answer to: What number multiplied by itself gives an answer of 2?
