3rd Grade Math
posted by Kainalu Mauga .
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.

You have to add the numbers.
You could multiply 4 by 2, since two people have four cards, and then add 3 to the result.
