Multiplication as a Model
1. Think about multiplication as a model. In your head, what is a model? A model can be many things. A model can be a person who gets there picture taken. A model can also be used to symbolize or show something, which is exactly how we think of models in math. Look at this example below:
XXX XXX XXX XXX
1 2 3 4
There are 4 different groups with exactly three in each group. Therefore, we have 3 groups of 4. Now think about this model as a multiplication equation. There are 3 groups of 4 in each group. As a multiplication equation, this would look like 3 x 4 = 12.
2. Look at the image below. The following image shows another example of a multiplication model.
XXX XXX XXX XXX
1 2 3 4
There are 4 different groups with exactly three in each group. Therefore, we have 3 groups of 4. Now think about this model as a multiplication equation. There are 3 groups of 4 in each group. As a multiplication equation, this would look like 3 x 4 = 12.
2. Look at the image below. The following image shows another example of a multiplication model.
3. Watch the following video to see how a multiplication model can be created using base 10 units or counters.
4. Now it is your turn. Take the base 10 units or counters you have by your computer. Create a model using your manipulatives for the following 3 multiplication equations:
1. 6 x 4 =
2. 9 x 6 =
3. 3 x 9 =
Write the equations on your piece of paper and find the product (answer in a multiplication equation). Raise your hand for a teacher to check your work before moving on to the next section.
