Example Question #1 : Solve Two Step Word Problems Using The Four Operations: Ccss.Math.Content.3.Oa.D.8

Jessica has been collecting beads all summer. She started with  beads and by the end of the summer she was able to add  more beads to her collection.  On the first day of school she wants to evenly split the beads up amongst her  friends.  How many beads will each friend get? 

Possible Answers:

Correct answer:

Explanation:

To solve this problem, we first have to find our unknowns. Our unknowns are the number of beads she will have by the end of the summer and the number of beads each of her friends will receive. We can set up equations for these unknowns by letting  represent the beads that she has at the end of the summer and  represent the number of beads each of her friends will receive. 

  because she gets  more beads by the end of the summer.

 because she is splitting up her total amount of beads between  friends. When you split something up evenly you divide.
