Identify the factors of multiplication expressions for arrays

How to identify the factors of multiplication by observing an array?

One can tell you many theories about reading multiplication arrays quizzes for Grade 3, but some good examples are worth more than 1000 words.

Here is a beautiful selection of everyday objects that will help children better understand how to interpret an array. They can then retrieve information such as the number of rows and columns easily. Those data will then allow writing a multiplication expression to determine how many entries or objects the array has in all.

For example, if an array has 5 rows and 10 columns, the corresponding multiplication expression that describes this array is 5 x 10 = 50

How to identify multiplication expressions for arrays

The following example will help kids for the reading multiplication arrays quizzes for Grade 3. For multiplication, the numbers being multiplied are called factors. It is these factors that must be identified in an array in order to write the multiplication expression.

Now look at this case that will serve as an example.

Now look at this case that will serve as an example. Consider the following problem: in a large box, boxes of milk are arranged in two rows and four columns. How many boxes of milk are there in all in that box?

This array represents our word problem. From this representation, we deduce the multiplication expression that describes the model: 2 rows and four columns give 2 x 4 = 8 milk boxes.
To redo a brief review on the other way to describe our array, as we are interpreting the array or the problem, we can infer the following repeated addition: 4 + 4 = 8. With the equal groups we will get 2 groups of 4 boxes of milk.
