Marlon has 4 baseball cards, Jake has 4 baseball cards and Sam has 3 baseball cards. Can you write a multiplication sentence to find how many baseball cards they have altogether? Explain.

No. I can't write a multiplication sentence for this problem. I can write an addition sentence for this problem.

Please explain why you can't write a multiplication sentence.

There's nothing to multiply.

To find how many baseball cards Marlon, Jake, and Sam have altogether, we can write a multiplication sentence.

First, let's write down the number of baseball cards each person has:
Marlon: 4 cards
Jake: 4 cards
Sam: 3 cards

To find the total number of cards, we need to add up the individual amounts. Since we are dealing with multiplication, we can multiply the number of cards each person has by 1 to get the total number of cards.

We can write the multiplication sentence using the number of cards for each person:

Total Number of Cards = (Number of Cards for Marlon) x (Number of Cards for Jake) x (Number of Cards for Sam)
Total Number of Cards = 4 x 4 x 3

To solve this multiplication sentence, we multiply the numbers together:

Total Number of Cards = 48

Therefore, Marlon, Jake, and Sam have a total of 48 baseball cards altogether.
