What is the Repeated Addition Multiplication

Concept?

When we multiply, the result is the total number, referred

to as the product. In multiplication, we combine a certain

number of groups, which is the multiplier. Each group

has the same quantity, which is the multiplicand. Because

addition and multiplication are interrelated operations, we

obtain the same results by repeated addition. For example,

3 x 5 = 5 + 5 + 5. There are 3 groups of 5. Some students

are encouraged to memorize multiplication facts before

they understand the concept of multiplication. The result

is inconsistent surface knowledge. Working with repeated

addition builds the necessary foundations for permanent

ownership of multiplication facts.

Formative Assessment

To fi nd out if a student understands repeated addition

multiplication, give the student the following repeated

addition equations and ask the student to give the related

multiplication equation.

3 + 3 + 3 + 3 = 8 + 8 + 8 =

If the student is successful, provide the following

multiplication equations and ask the student to give the

related repeated addition equations.

7 x 4 = 6 x 9 =

If the student is not successful with either set of problems, try

groups of two, fi ve, or ten. If the student is successful with

both sets of problems, try more complex problems.
