describe classes of numbers according to characteristics such as the nature of their factors

Factors	Lesson: Students learn about factoring by using manipulatives and computer applets.
Finding Factors	Lesson: Finding the factors of whole numbers.
Factorize	Activity: Visualize factors through building rectangular areas on a grid. First enter all the factorizations of a number, then draw each factor set as an area on the grid. Factorize is one of the Interactivate assessment explorers.
Factorize 2	Activity: Visualize factors through building rectangular areas on a grid. As you draw each factor set on the grid, the factors will be listed. Factorize 2 is one of the Interactivate assessment explorers.

develop understanding of fractions as parts of unit wholes, as parts of a collection, as locations on number lines, and as divisions of whole numbers

Fraction Conversion	Lesson: Motivate converting fractions to decimals with the use of money.
Fraction King	Lesson: Students and teacher play a game called "Fraction King" to seed the idea of taking fractions of whole numbers then use manipulatives and several computer applets to concretize the idea.

recognize and generate equivalent forms of commonly used fractions, decimals, and percents

Fraction Conversion	Lesson: Motivate converting fractions to decimals with the use of money.
Ideas for Working with Fractions	Lesson: Students get practice working with conversion of fractions, decimals, percents through using several of the Interactivate activities.
Fraction King	Lesson: Students and teacher play a game called "Fraction King" to seed the idea of taking fractions of whole numbers then use manipulatives and several computer applets to concretize the idea.
Playing with Probability	Lesson:
Fraction Conversion	Lesson: Motivate converting fractions to decimals with the use of money.
Fraction Facts	Lesson: Introduces students to fractions and explores basic mathematical operations with fractions, comparing fractions, and converting fractions into decimals or percents.
Fraction King	Lesson: Students and teacher play a game called "Fraction King" to seed the idea of taking fractions of whole numbers then use manipulatives and several computer applets to concretize the idea.
Equivalent Fractions Finder	Activity: Visually represent two unique fractions that are equivalent to a given fraction. The fractional value is shown on a number line after you check to see if your fraction is correct. Equivalent Fraction Finder is one of the Interactivate assessment explorers.
Equivalent Fractions Pointer	Activity: Visually represent two unique fractions that are equivalent to a given fraction. The fractional value is shown on a number line as you color in the fraction. Equivalent Fraction Pointer is one of the Interactivate assessment explorers.

recognize equivalent representations for the same number and generate them by decomposing and composing numbers

Fraction Conversion	Lesson: Motivate converting fractions to decimals with the use of money.
Introduction to Fractals: Infinity, Self-Similarity and Recursion	Lesson: Introduces students to the ideas involved in understanding fractals.

understand the place-value structure of the base-ten number system and be able to represent and compare whole numbers and decimals

Comparing Fractions	Lesson: Introduces students to fractions and explores basic mathematical operations with fractions, comparing fractions, and converting fractions into decimals or percents.
Estimation (elementary)	Lesson: Students practice and improve upon their estimation skills.
Fraction Pointer	Activity: Graphically determine the value of two given fractions represented as points on a number line. Graphically find a fraction whose value is between the two given fractions (using an arrow on the number line as a guide), then determine its value. Fraction Pointer is one of the Interactivate assessment explorers.
Fraction Sorter	Activity: Visualize fractions by coloring in the appropriate portions of either a circle or a square, then order those fractions from least to greatest. Fraction Sorter is one of the Interactivate assessment explorers.
