Question

name
a group of 35 students and 5 teachers went on a field trip. each teacher supervised an equal number of students during the field trip. which model can be used to find the number of students each teacher supervised?
a
image of a bar model with five boxes labeled 35 and a question mark for the total
b
image of a bar model with one box labeled 5 and a question mark for the remaining part, total labeled 35
c
image of a bar model with one box labeled 5 and one box labeled 35, question mark for the total
d
image of a bar model with five boxes labeled?, total labeled 35

Explanation:

Step1: Analyze the problem

We have 35 students and 5 teachers. We need to find how many students each teacher supervises, which is a division problem: we want to split 35 students into 5 equal groups (one group per teacher).

Step2: Analyze each option

• Option A: Shows 5 groups of 35, which would represent \( 35\times5 \), not what we need.
• Option B: Shows a total of 35 with one part as 5 and the other as "?", which would be \( 35 - 5 \), not relevant.
• Option C: Shows 5 and 35 as parts with a total "?", which would be \( 5 + 35 \), not relevant.
• Option D: Shows 5 equal groups (since there are 5 "?" boxes) that add up to 35, which represents dividing 35 into 5 equal parts, i.e., \( 35\div5 \), which is what we need.

Answer:

D. \( \boxed{D} \)
