What is Missing Factors Multiplication? Generally, in a multiplication sum, you are given two numbers and are supposed to multiply them and find out their product. Missing factors multiplication is a bit different. A missing factor multiplication sum provides you with a number and the answer it will produce upon being multiplied by another number (the factor). Hence, as the name implies, in a missing factor multiplication sum, you have to find out the number that will produce the given answer upon being multiplied by the other given number. There is a simple technique for doing that. You can simply divide the given answer by the other given number. The division will produce that missing factor because division and multiplication are reciprocals of each other. Here is how it is done: A typical multiplication sum can go like 9 x 3 = ___. Calculating the answer, in this case, can be pretty simple. All you have to do is multiply 9 by 3, and you get an easy answer of 27. In the case of missing factor multiplication, the sum will be 9 x ___ = 27. Here you have to guess the number that upon being multiplied by 9 gave the answer of 27 or simply divide 27 by 9 to give the answer of 3. Here was a quick guide on what is missing factors multiplication and how it is done. These worksheets and lessons help students learn to identify missing factors in multiplication problems with ease.

- Step-by-Step Lesson- Time to start the process of learning one step algebra.
- Guided Lesson - We go back to a horizontal start format.
- Guided Lesson Explanation - It is a really good idea to get into the habit of placing your own variable in the blank space.
- Practice Worksheet 1 - A horizontal orientation of the products. It mirrors the guided lesson.
- Practice Worksheet 2 - If students can rocket through this, they have mastered the basic skill.
- Missing Factor 5-Pack - A lot of great practice sheets for you to work through.

#### Homework Sheets

The first two sheets focus on the horizontal format and the last one is in a vertical format.

- Homework 1 - This is the first step towards products solved by algebra.
- Homework 2 - Start every problem by understanding what the problem is telling us.
- Homework 3 - If you have an equal symbol, you have an equation.

#### Practice Worksheets

We run the inverse to the homework sheets. Start with two verticals and end off with an horizontal.

- Practice 1 - You mathematically do whatever you want to an equation as long as you do the same thing to both sides of the equal sign.
- Practice 2 - When we are tackling finding missing parts of an equation all that we need to do is work on getting the unknown factor by itself.
- Practice 3 - If we reverse the operation that is being applied to the unknown number, we will get the unknown number by itself.
