Solve the following word problems by using an Open Number Line.  Don't be afraid to take a picture and then explain your answer.

1. Samuel has been saving the tickets that he wins from the arcade.  He has a total of 63 red and purple tickets.  If 26 of the tickets are red, how many purple tickets does he have?

2. Eli's school has 29 more students in first grade than in second grade.  If there are 63 students in second grade, how many students are in first grade?

Challenge yourself!  Can you use more than one strategy to solve the word problems?
