93. Which of the following word problems will second-grade students be most likely to solve using addition?
Answer: B
Students will solve the problem about the school bus using addition.
The word problem regarding the school bus is most likely to be solved using addition because it requires students to find the total number of students after an increase, which directly involves adding the number of new students to the existing total.
A) Mr. John has 25 stickers to distribute equally among five students. How many stickers will each student get?
This problem is focused on division, as it involves distributing a total of 25 stickers evenly among five students. Second-grade students would need to use division to determine how many stickers each student receives, making this option incorrect for an addition-focused question.
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?
This problem clearly requires addition, as students must add the 12 new students to the existing 28 to find the total number of students on the bus. This straightforward addition aligns well with the skills expected of second-grade students.
C) A carton has 18 eggs, but 7 of them are cracked. How many eggs in the carton are not cracked?
This problem involves subtraction, as students need to determine the number of non-cracked eggs by subtracting the 7 cracked eggs from the total of 18. Thus, it does not pertain to an addition problem, making it an incorrect choice.
D) Jack gave Chris 12 markers, and now Chris has 19 markers. How many markers did Chris have before Jack gave him 12?
This question is also based on subtraction, as it asks for the original number of markers Chris had before receiving 12 more. Students would need to subtract 12 from 19 to find the answer, which does not involve addition.
Conclusion
The only word problem that requires addition is option B, where students must add the number of additional students to the initial total. Options A, C, and D involve division or subtraction, thus failing to meet the criteria of using addition. Therefore, option B is the correct choice for second-grade students to practice addition skills effectively.
