how to represent quantities using different units. Estimate and measure
quantities of length, mass, and capacity, and solve measurement
problems.
What Is a Number System?
Understand the nature of the real number system, the elements and
operations that make up the system, and some of the rules that govern the operations. Examine a finite number system that follows some (but not all) of the same rules, and then compare this system to the real number system. Use a number line to classify the numbers we use, and examine how the numbers and operations relate to one another.
Number Sets, Infinity, and Zero
Continue examining the number line and the relationships among sets of numbers that make up the real number system. Explore which operations and properties hold true for each of the sets. Consider the magnitude of these infinite sets and discover that infinity comes in more than one size. Examine place value and the significance of zero in a place value system.
Place-Value Centers
First-graders develop an understanding of the numeration system by
relating counting, grouping, and place-value concepts. Activities
include measuring with Unifix cubes and using base-ten blocks. NCTM
standards: number sense and numeration, measurement, connections.
Student Diversity Workshop 5
