Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.

Place value is a building block of numbers. Without place value, we couldn't keep all our numbers straight! This tutorial introduces place value and shows you the parts of a place value chart.

Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

Finding equivalent fractions is an important part of things like adding, subtracting, and comparing fractions. But what are they? In this tutorial, you'll learn that equivalent fractions are just fractions that have the same value, even though they may look very different!
