In previous grades, students understood multiplication as equal groups. This lesson introduces multiplication as scaling. Students already know that multiplying a number by 1 results in the original number. Now they learn that multiplying a number by a whole number greater than 1 results in a produ...
the second factor is a number showing how many times the first factor must be added to obtain the product; product is the value obtained from repeated addition, showing what this operation is equal to.Multiplication belongs to the third Common Core math topic for learning. Hence, explain the ...

An array is a way to organize groups of objects into equal rows and columns. When we use an array, we create horizontal rows of numbers and vertical columns of numbers. This allows us to visualize how multiplication represents combining or grouping elements. ...
When students use these two strategies and make groups to calculate the requested value, they do not think about the properties of multiplication, nor the array model. However, the analysis of these strategies and the solution for other situations based on the same type of context can lead to...
Greer [56] classified four situations that can be modeled by multiplication, which include (1) equal groups—a number of groups of objects having the same number in each group, (2) multiplicative comparison—verbally expressed by “n times as many as” so that an amount of objects expands ...
number of skittles. For example, one girl had 24 skittles, so she was able to make 8 groups of 3and6 groups of 4, etc. It was also a great way to discuss thecommutative propertyand show that if they could make 8 equal groups of 3, then they could also make 3 equal groups of 8...
