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 requires students to combine two quantities through addition, making it a straightforward addition word problem. The scenario clearly presents an initial quantity of students and asks for the total after an increase, which aligns with the addition skills second-grade students are learning.

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

This problem involves division rather than addition. It asks how many stickers each student will receive when the total is divided equally, which is not a task that requires addition to solve.

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 answer as it explicitly asks for the total number of students after an increase, requiring students to add the initial number of students (28) to the number of new students (12). This directly utilizes the addition skills appropriate for second graders.

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 students to find the difference between the total number of eggs and the cracked eggs, which involves subtraction. Therefore, it does not align with the goal of identifying a problem that uses addition.

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 requires students to deduce a previous quantity by subtracting the number of markers given from the current total. It focuses on backward reasoning rather than performing addition, making it unsuitable for this question.

Conclusion

The question aims to identify a scenario suitable for second graders to apply addition skills effectively. Among the options, only the scenario involving the school bus (option B) presents a clear addition problem by asking for a total after an increase in quantity. The other options either involve division or subtraction, which do not meet the criteria for solving through addition.
