4 dice

Let’s clean up the dice!

How many dice are there?

Here is a multiplication picture of the pieces. Multiplication pictures help us see how many groups of items there are. They help us see how many items are in each group.

2 sets of 2 dice circled

We can also use an array to show the same thing. Here is an array that shows the number of dice we have.

2 rows of two dots

Let’s use the picture and array to write and solve a word problem! Word problems tell us a story using math. Multiplication word problems have key words that tell us to multiply.

Multiplication Key Words

by

per

of

each

in all

total

We will fill in the important numbers. Then we will find the total number of dice.

Multiplication Picture

Here is the multiplication picture of the dice.

2 sets of 2 dice circled

We need to know how many groups there are and how many are in each group. The circles are the number of groups. The number of items in each circle is the number in each group.

Question 1:

How many groups are there?

Question 2:

How many are in each group?

Array

Here is the array.

2 rows of two dots

We need to know how many groups there are and how many are in each group. The rows are the number of groups. The number of dots in each row is the number in each group.

Question 1:

How many groups are there?

Question 2:

How many are in each group?

Important Numbers

Both the multiplication picture and the array showed that there are 2 groups with 2 in each group.

There are __ groups of __ dice on the floor. How many dice in all do we need to put away?

We need to fill in the important numbers. The first blank is the number of groups. The second blank is the number in each group. Click Mock show me buttonto see where the numbers go!

Addition Sentence

Here is the word problem we created!

There are 2 groups of 2 dice on the floor. How many dice in all do we need to put away?

Now we need to solve it! Let’s start with the repeated addition sentence.

Question:

What repeated addition sentence can we use?

Multiplication Sentence

We can use 2 + 2 = ?

There are 2 groups of 2 dice on the floor. How many dice in all do we need to put away?

2 + 2 = ?

We also need a multiplication sentence.

Question:

What multiplication sentence can we use?

Total Number

We can use 2 x 2 = ?

There are 2 groups of 2 dice on the floor. How many dice in all do we need to put away?

2 sets of 2 dice circled
2 rows of two dots

2 + 2 = ?

2 x 2 = ?

How can we find the total number of dice on the floor? We can use the multiplication picture. We can use the array. We can also use the repeated addition sentence. You can choose what works for you! Click Mock show me buttonto see each way to find the answer!
