Index: 4.1A Grade 8 CPI 5

 

Standard: 4.1 - Number and Numerical Operations

 

Strand: C - Estimation

 

Cumulative Progress Indicator: 5 -  The student will use whole numbers, fractions, decimals, and percents to represent equivalent forms of the same number.

 

Grade: 8

 

Sample Activities:

 

·        Given a circle graph of some interesting data, students estimate the size of each section of the graph as a fraction, a percent, and as a decimal. Students also create their own circle graphs.

 

·        Students use two different-color interlocking paper circles (each has a cut along a radius so they fit together), each marked off in wedges that are one hundredth of the circle, to show fractions that have denominators of 10 or 100, decimals to hundredths, and whole number percents to 100%

 

·        Students explore patterns in particular families of decimal expansions, such as those for the fractions, 1/7, 2/7, 3/7, ... or 1/9, 2/9, 3/9, ...
