Students will learn how to factor numbers by using manipulatives and computer applets.

Understand numbers, ways of representing numbers, relationships among numbers, and number systems

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

- understand the effects of multiplying and dividing whole numbers;
- identify and use relationships between operations, such as division as the inverse of multiplication, to solve problems;

- develop fluency in adding, subtracting, multiplying, and dividing whole

*Technological*:

Students must be able to:- perform basic mouse manipulations such as point, click and drag.
- use a browser such as Netscape for experimenting with the activities.

Students will need:

- access to a browser.
- access to pencil and paper.

**Focus and Review**- Pass out 2 pieces of graph paper to each student.
- Instruct the students to draw all possible rectangles with an area of 10 squares.
- The students should draw squares with dimensions of 1x10, 2x5, 5x2, and 10x1.
- Call on several students to draw their rectangles on the board.
- Next, instruct the students to draw all possible rectangles with an area of 24 squares.
- Continue having the students draw rectangles for different size areas until they recognize that there is a connection between the dimensions of the rectangles and the area of the rectangles.
- Call on a student to explain this connection to the class.

**Objectives**
Students will demonstrate their ability to list the factors for different numbers.
**Teacher Input**- Explain to the class the term factor.

**Guided Practice**- Work a few problems with the class demonstrating how to using the Factorize and the Factorize 2 applets.

**Independant Practice**- Instruct the students to work 10 computer generated problems from each applet.

**Closure**
Review the term factor and some different methods that can be used to
find the factors of a given number.
