Core Concepts

Learn how to find the total number of items in equal groups by using repeated addition. This is a key step before learning the multiplication symbol!

Counting with Repeated Addition

1 of 15

You have $3$ groups of $2$ apples. How can you write this as an addition problem to find the total?

$$2 + 2 + 2$$

What is the total for $2 + 2 + 2$?

$$6$$

You have $4$ groups of $5$ stars. How would you write this as a repeated addition sentence?

$$5 + 5 + 5 + 5$$

What is the total for $5 + 5 + 5 + 5$?

$$20$$

A sentence like $3 + 3 + 3 + 3$ is called...

A repeated addition sentence.

Why is $3 + 3 + 3 + 3$ a repeated addition sentence?

Because you are adding the same number ($3$) over and over again.

Is $4 + 2 + 4$ a repeated addition sentence?

No, because the numbers being added are not all the same. You are adding $4$ and $2$.

There are $2$ nests with $4$ eggs in each. Write the repeated addition sentence to find the total number of eggs.

$$4 + 4$$

What is the total number of eggs if there are $2$ nests with $4$ eggs each? ($4 + 4 = ?$)

$$8$$

There are $5$ bags with $3$ cookies in each. Write the repeated addition sentence for the total number of cookies.

$$3 + 3 + 3 + 3 + 3$$

What is the total number of cookies if there are $5$ bags with $3$ cookies each?

$$15$$

$$6 + 6 + 6 = ?$$

$$18$$

Write a repeated addition sentence for $4$ groups of $10$.

$$10 + 10 + 10 + 10$$

What is the total for $10 + 10 + 10 + 10$?

$$40$$

Does $1 + 2 + 3 + 4$ represent finding the total of equal groups?

No, because the groups would have sizes of $1$, $2$, $3$, and $4$. They are not equal.
