There are five monsters. Each monster has six eyes. There are five groups of six eyes. Think about how we can find the total number of eyes. This model shows five groups of six eyes. Noah says, “I can add.” Hannah says, “I can multiply.” Help Noah write an addition expression for the total number of eyes.

Noah should write six plus six plus six plus six plus six. There are one, two, three, four, five groups of six. There are five sixes shown in our model.

Help Hannah by writing a multiplication expression for the total number of eyes.

There are five groups of six. So, Hannah could write five multiplied by six.

How many eyes are there?

We could use our knowledge of the six times table, or count in sixes. Six plus six plus six plus six plus six equals 30. Five multiplied by six equals 30. There are 30 eyes altogether. We could find our answer using a repeated addition sentence or a multiplication sentence.
