Which of the following word problems will second-grade students be most likely to solve using addition?

Rationale

There are 28 students on a school bus. If 12 more students get on the bus, how many students will be on the bus?

This problem involves determining a total after an increase, which is a classic addition scenario suitable for second-grade students. They are expected to use addition to find out how many students will be on the bus after the additional students board.

A (Mr. John has 25 stickers to distribute equally among five students. How many stickers will each student get?) YOUR ANSWER

This problem requires division, as it asks how many stickers each student receives when the total is equally distributed. Second-grade students would need to understand how to split the total into equal parts, which is not an addition problem.

B (There are 28 students on a school bus. If 12 more students get on the bus, how many students will be on the bus?) CORRECT

This is the correct option because it straightforwardly asks for the total number of students by adding the number of students currently on the bus to the number of new students getting on. This scenario aligns perfectly with what second graders learn about addition.

C (A carton has 18 eggs, but 7 of them are cracked. How many eggs in the carton are not cracked?) YOUR ANSWER

This problem requires subtraction to find out how many uncracked eggs remain. Second graders would need to subtract the cracked eggs from the total, making it a subtraction problem rather than an addition one.

D (Jack gave Chris 12 markers, and now Chris has 19 markers. How many markers did Chris have before Jack gave him 12?) YOUR ANSWER

This problem involves finding a missing addend, which requires subtraction to determine how many markers Chris originally had. Although it relates to addition, it is not a direct addition problem for the students to solve.

Conclusion

In summary, the most suitable problem for second-grade students to solve using addition is the one about the students boarding the bus. The task clearly calls for them to add numbers together, aligning with their learning objectives. Other options involve division or subtraction, which do not fit the criteria for an addition problem, emphasizing the importance of recognizing operations in word problems.
