Index: 4.1A Grade 8 CPI 4

 

Standard: 4.1 - Number and Numerical Operations

 

Strand: C - Estimation

 

Cumulative Progress Indicator: 4 -   The student will compare and order numbers of all named types.

 

Grade: 8

 

Sample Activities:

 

·        Students use concrete and pictorial models to develop order relations among fractions and integers. Using Cuisenaire Rods and varying the unit, students demonstrate that one fraction is larger than another. Similar arguments and conclusions are made on a number line for integers.

 

·        Students' abilities to order rational numbers (both positive and negative) are assessed by asking them to identify points on a number line between, say, -3 and -5.

 

·        Students are each given a rational number on a large card (-1.2, 4, 3/4, -2 1/4, -1, 3.14, 22/7, and so on). They then order themselves from least to greatest along the front or side of the classroom. They also respond to instructions like: Hold up your card if it is between -2.5 and +0.7.
