Variant 1 medium

The number of students in each group of Ethan's class was surveyed and shown in a graph. Find the total number of students in the group where the difference between the number of girls and the number of boys is the greatest.

The graph is titled "Number of students by group." The horizontal axis shows the groups $1, 2, 3, 4$ , and the vertical axis shows the number of students from $1$ to $5$ . For each group, the open circles (girls) and the filled circles (boys) are stacked separately.

Group $1$ : girls ( $\circ$ ) $4$ , boys ( $\bullet$ ) $3$
Group $2$ : girls ( $\circ$ ) $1$ , boys ( $\bullet$ ) $5$
Group $3$ : girls ( $\circ$ ) $5$ , boys ( $\bullet$ ) $2$
Group $4$ : girls ( $\circ$ ) $2$ , boys ( $\bullet$ ) $5$

1 · Understandwhat's really being asked

A graph shows the number of girls and boys in each of 4 groups. Find the group where the gap between girls and boys is the largest, then report the total number of students in that group.

Givens

Group 1: 4 girls, 3 boys.
Group 2: 1 girls, 5 boys.
Group 3: 5 girls, 2 boys.
Group 4: 2 girls, 5 boys.

Unknowns

The total number of students in the group with the greatest difference between girls and boys.

Constraints

The difference is how many more of one group there are than the other (a non-negative number).
The total of a group is girls plus boys.

There are only 4 groups, so I list each group's girl-boy difference one at a time (a subproblem per group), pick the biggest difference, then add that group's girls and boys for the total.

#2 Make a Systematic List 2.MD.D.10

For each group subtract the smaller count from the larger: Group 1 is 4-3=1; Group 2 is 5-1=4; Group 3 is 5-2=3; Group 4 is 5-2=3.

4-3=1,\ 5-1=4,\ 5-2=3,\ 5-2=3

Reading two stacked columns per group lets you compare girls and boys directly by subtracting.

Comparing the differences 1, 4, 3, 3, the largest is 4, which belongs to Group 2.

3Total the winning group

#7 Identify Subproblems 2.MD.D.10

Group 2 has 1 girls and 5 boys, so its total is 1+5=6 students.

1+5=6

The total of a group is just the two columns added together.

Answer: 6 students

4 · Reviewdoes it hold up?

Group 2 has the most lopsided split (5 vs 1), matching the largest difference of 4, and its total 6 adds up correctly.

Another way: Read off both columns for every group, write each total and each difference in a small two-column table, and scan the difference column for its maximum.
