Index: 4.1C Grade 6 CPI 1

 

Standard: 4.1 - Number and Numerical Operations

 

Strand: C - Estimation

 

Cumulative Progress Indicator: 1 -  The student will use a variety of strategies for estimating both quantities and the results of computations.

 

Grade: 6

 

Sample Activities:

 

·        In their beginning work with percent, students master the common fraction equivalents for familiar percentages and use fractions for estimation in appropriate situations. For example, an estimate of 65% of 63 can be easily obtained by considering 2/3 of 60.

 

·        Students use fractions, decimals, or mixed numbers interchangeably when one form of a number makes estimation easier than another form. For example, rather than estimating the product 3/5 x 4, students consider 0.6 x 4 which yields a much quicker estimate.
