AZ Math Standards Performance Objectives (samples):

Strand 1: Number Sense and Operation

Concept 1: Number Sense

• Grade 3 PO 18: Order three or more decimals, through hundredths, using models,

illustrations, or symbols.

• Grade 4 PO 15: Compare two decimals

• Grade 5 PO7: Order whole numbers, fractions, and decimals.

Directions:

Place Value Chart: Represent the decimal point by placing the chip between the columns on the

place value chart. Construct decimals numbers using base ten blocks and this place value chart.

Example: Represent the number 2.31 using the base ten blocks or chip abacus.

Since our decimal point is located between the flat and the rod, the flat represents one.

The rod represents one-tenth of the flat which as a fraction is

and as a decimal is 0.1.

The small cube represents one one-hundredth of the flat which as a fraction is

and as

100

a decimal is 0.01. When we apply the multiplicative and additive properties of our base

ten number system, we say that the number represented in the chart

NOTE: Place values change when the decimal point is moved.
