MULTIPLICATION
We are no longer taught only one strategy to solve multiplicaiton equations. We are now taught a variety of strategies, so that we can choose the strategy that works best for us and our understanding. Here are a couple of examples of the different types of strategies that we can use to solve multiplication.
Area Model
When completeing an area model, we need to understand how to break up a number using place value and expanded form. For example 28 is the same as 20+8 and 36 is the same as 30+6. We can then line up one equation on the top and one on the side. Afterwards, we complete a series of multiplicaiton problems using the the simple equations and the power of zero. To find the final answer, I can add up all of the friendly numbers in the box.
Break-Up
For some students it is easier to see a large multiplication equation as a couple of smaller, and simpler equations. In the break-up strategy, we can create smaller equations by breaking up the larger number. For example, 7x8 is the same as (7x4)+(7x4). Since 7x4=28, I only need to add 28+28 to find the final solution.
Standard
Using the standard form can be simple for some and difficult for others to follow. The standard form is the way that most adults were taught to multiply when they were in school!
Memorization
We will naturally begin to memorize some of the multiplicaiton facts, and in many cases it is useful to do so. Just remember, you always need to have a strategy to solve the equation if you do not have it memorized! Click the link above to practice your multiplication facts.
