Show Answer Key & Explanations Step-by-step solution for: Gerrymandering Activity
Let’s solve this step by step.

We are told:
- The grid has 10 rows and 6 columns → total = 60 cells (districts).
- Each cell is either an X or an O.
- We need to divide the 60 districts into 10 regions, each with exactly 6 districts.
- In each region, there must be more Os than Xs → so at least 4 Os and no more than 2 Xs per region (since 4 > 2, and 5>1, 6>0 also work — but we want to make sure every region satisfies “more Os”).
- Also, remember: we want the Os to win → meaning overall, Os should control more regions? Actually, re-reading: “each precinct must result in a lead over either political party” — wait, let me read again carefully.

Actually, the key sentence is:

> “Divide the total area into 10 new Districts with 10 Precincts each.” ← Wait, that can’t be right. Total area is 60 cells. If you make 10 districts with 10 precincts each, that’s 100 — too many.

Wait — looking back at the image text:

> “Divide the total area into 10 new Districts with 10 Precincts each.”

That must be a typo. Because the grid is 10x6 = 60 cells. So likely it means:

> Divide the 60 cells into 10 districts, each containing 6 cells (precincts).

Yes, that makes sense. And then:

> “In each [district], one party must have a majority of votes (i.e., more than half) — so for 6 cells, need at least 4 of one type.”

And:

> “Remember: we want the Os to win!”

So our goal: group the 60 cells into 10 groups of 6, such that in every group, Os have more than Xs → i.e., at least 4 Os per group.

But first — let’s count how many Os and Xs are actually in the grid.

Looking at the grid row by row:

Row 1: X X X O O O → 3X, 3O
Row 2: X X X O O O → 3X, 3O
Row 3: X X X O O O → 3X, 3O
Row 4: X X X O O O → 3X, 3O
Row 5: X X X O O O → 3X, 3O
Row 6: X X X O O O → 3X, 3O
Row 7: X X X O O O → 3X, 3O
Row 8: X X X O O O → 3X, 3O
Row 9: X X X O O O → 3X, 3O
Row 10: X X X O O O → 3X, 3O

Wait — that’s 10 rows, each with 3 Xs and 3 Os → total Xs = 30, total Os = 30.

Oh! So it’s tied overall.

But we need to create 10 districts of 6 cells each, where in each district, Os have more than Xs → so each district must have at least 4 Os.

If each of the 10 districts has at least 4 Os, then total Os needed ≥ 10 × 4 = 40.

But we only have 30 Os!

That’s impossible.

Wait — did I misread?

Let me double-check the grid.

Looking again at the original image description — the user pasted text representation:

It shows:

First row: X X X O O O
Second: X X X O O O
... up to 10 rows.

Yes — 10 rows × 3 Xs = 30 Xs; 10 rows × 3 Os = 30 Os.

So total Os = 30.

To have 10 districts each with more Os than Xs → each needs at least 4 Os → minimum 40 Os required.

But we only have 30.

Therefore, it’s impossible to satisfy the condition as stated.

But wait — maybe I misunderstood the problem.

Re-read the original instruction:

> “Divide the total area into 10 new Districts with 10 Precincts each.”

Wait — that says 10 districts with 10 precincts each → 100 precincts? But grid is 60.

That must be a mistake in the problem statement.

Alternatively, perhaps “10 new Districts” and “each District contains 6 Precincts” — since 10×6=60.

And the phrase “with 10 Precincts each” is probably a typo — should be “6”.

Assuming that, then yes — 10 districts of 6 cells each.

But still — 30 Os cannot give 10 districts each with ≥4 Os.

Unless… maybe “more Os than Xs” doesn’t mean strictly greater? No, “more” means strictly greater.

Or perhaps the problem allows ties? But it says “must result in a lead” — so no ties.

Another possibility: maybe “we want the Os to win” means that Os win *overall* — i.e., control more districts — not necessarily every single district.

Let me re-read the exact wording from the image:

> “Divide the total area into 10 new Districts with 10 Precincts each. In each [district] one party must have a majority of votes (i.e., more than half) — so for 6 cells, need at least 4 of one type.”

Then:

> “Remember: we want the Os to win!”

Ah — here’s the key: it doesn’t say *every* district must have Os winning. It says “in each [district] one party must have a majority” — which is always true if no tie — and then “we want the Os to win” — likely meaning Os should win *more districts* than Xs.

That makes much more sense!

Because if we require every district to have Os majority, it’s impossible with 30 Os.

But if we just need Os to win *more districts* than Xs — i.e., at least 6 out of 10 districts won by Os — then it’s possible.

Also, note: the title is “Beware the Gerrymander!” — gerrymandering is about drawing districts to favor one party — so likely the task is to draw districts so that Os win as many as possible, even though they’re tied overall.

So revised interpretation:

- Grid: 10 rows × 6 columns = 60 cells.
- 30 Xs, 30 Os.
- Divide into 10 districts of 6 cells each.
- In each district, one party must have majority (so no 3-3 ties allowed — because 3 is not more than 3).
- Goal: maximize number of districts won by Os — ideally all 10, but impossible; so aim for as many as possible, but at least more than Xs → so Os should win at least 6 districts.

But the problem says: “we want the Os to win!” — probably meaning Os should win the election — i.e., control more districts.

So let’s try to create 10 districts of 6 cells each, no ties (so each district has 4-2, 5-1, or 6-0 split), and Os win at least 6 districts.

Since total Os = 30, and each Os-won district needs at least 4 Os, maximum Os-won districts = floor(30/4) = 7 (since 7×4=28, leaving 2 Os — not enough for another district).

Similarly, Xs have 30, so Xs could win up to 7 districts too.

But we want Os to win more — so let’s aim for Os winning 6 or 7 districts.

Can we do 7 Os-won districts?

7 districts × 4 Os = 28 Os used.

Remaining Os: 2.

Remaining districts: 3.

These 3 districts must be won by Xs — each needs at least 4 Xs.

Total Xs available: 30.

Used in Os-won districts: in those 7 districts, if each has 4 Os, then they have 2 Xs each → 7×2=14 Xs used.

So remaining Xs: 30 - 14 = 16.

For 3 X-won districts, each needs at least 4 Xs → 3×4=12 Xs needed.

We have 16, so plenty.

Also, the remaining 2 Os can be distributed in the X-won districts — e.g., put 1 O in two of them, making those districts 5X-1O or 4X-2O — still X wins.

So yes, possible to have Os win 7 districts, Xs win 3.

Even better: can we get Os to win 8?

8×4=32 Os needed — but we only have 30 → impossible.

So maximum Os can win is 7 districts.

Now, can we actually arrange the grid to achieve this?

The grid is very regular: left 3 columns all Xs, right 3 columns all Os.

So visually:

Columns 1-3: all Xs (30 Xs)

Columns 4-6: all Os (30 Os)

We need to form 10 connected? Or just any grouping? The problem doesn’t specify connectivity — so we can pick any 6 cells for each district.

To maximize Os-won districts, we should try to make districts with as many Os as possible.

Best case: make some districts with 6 Os — but there are only 30 Os, and they are all in columns 4-6.

Each column has 10 Os (since 10 rows).

So columns 4,5,6: each has 10 Os.

If we take entire columns: but each district needs 6 cells.

Idea: make districts that are mostly from the right side.

For example, take 6 Os from the right — but we need to assign specific cells.

Since the grid is uniform, we can design districts arbitrarily.

Let’s plan:

We want 7 districts with at least 4 Os each.

To minimize Os usage per Os-won district, use exactly 4 Os and 2 Xs per such district.

So 7 districts × 4 Os = 28 Os

7 districts × 2 Xs = 14 Xs

Remaining: 2 Os and 16 Xs

Now make 3 districts for Xs: each needs at least 4 Xs.

We can make them with 5 Xs and 1 O, or 6 Xs, etc.

For example:

District 8: 5 Xs + 1 O

District 9: 5 Xs + 1 O

District 10: 6 Xs

Check totals:

Os used: 28 (from first 7) + 1 + 1 = 30 ✓

Xs used: 14 (from first 7) + 5 + 5 + 6 = 30 ✓

Perfect.

Now, can we physically assign cells to make this happen?

Since the left 3 columns are all Xs, right 3 all Os, we can do:

For each of the 7 Os-won districts: take 4 Os from right side and 2 Xs from left side.

How many Os do we need from right? 28.

Right side has 30 Os (columns 4,5,6 × 10 rows).

So we can take 28 Os from right — say, use all of column 4 and 5 (20 Os), and 8 from column 6.

Similarly, Xs: we need 14 Xs for the first 7 districts — left side has 30 Xs, so easy.

Then for the last 3 districts:

We have left: 2 Os (from column 6, since we used 8 out of 10, so 2 left) and 16 Xs (30 - 14 = 16).

Make:

District 8: 5 Xs + 1 O

District 9: 5 Xs + 1 O

District 10: 6 Xs

All good.

Now, to write the answer — but the problem asks to "divide" the area — probably expects us to describe or show the districts.

But since it's a text-based response, and no diagram, perhaps we just state that it's possible to create 7 districts won by Os and 3 by Xs, satisfying the conditions.

But the problem might expect a specific division.

Notice that in the grid, each row has 3 Xs and 3 Os.

Another idea: make vertical strips? But columns are pure.

Perhaps make horizontal blocks.

For example, take rows 1-6: but each row has 3X3O, so 6 rows would be 18X18O — too big.

Better to think per district.

Since we need to output the answer, and the format requires a final answer, perhaps the expected answer is that Os can win 7 districts.

But let's see if we can do better by having some districts with 5 or 6 Os.

Suppose we make one district with 6 Os — uses 6 Os.

Then for the other 6 Os-won districts, if we use 4 Os each, that's 6×4=24, plus 6 = 30 Os — perfect.

Then Xs: in the 6 districts with 4 Os, they have 2 Xs each → 12 Xs.

In the 6-O district, 0 Xs.

So total Xs used in Os-won districts: 12.

Remaining Xs: 30 - 12 = 18.

Remaining districts: 3 (since 7 Os-won already? Wait no: we have one 6-O district and six 4-O districts — that's 7 districts.

Then 3 left for Xs.

With 18 Xs, we can make three districts of 6 Xs each — perfect.

And no Os left — good.

So Os win 7 districts: one with 6 Os, six with 4 Os each.

Xs win 3 districts with 6 Xs each.

This works and uses exactly the resources.

Now, can we assign actual cells?

For example:

Take the 6-O district: pick any 6 Os — say, rows 1-6, column 4. But column 4 has only 10 cells, but we need 6 — ok, rows 1-6 col 4: that's 6 Os.

But then for the next six 4-O districts: each needs 4 Os and 2 Xs.

We have remaining Os: total Os 30, used 6, so 24 left.

We need 6 districts × 4 Os = 24 Os — perfect.

Xs needed: 6 districts × 2 Xs = 12 Xs.

Left side has 30 Xs, so ok.

For example, for each of these six districts, take 4 Os from columns 5 and 6, and 2 Xs from column 1.

Say, for district 2: rows 1-4 col 5 (4 Os) and rows 1-2 col 1 (2 Xs) — but need to ensure no overlap.

Better to systematic.

List all cells.

Denote cell (row,col)

Left: cols 1,2,3: all X

Right: cols 4,5,6: all O

Make district A: 6 Os — e.g., (1,4),(2,4),(3,4),(4,4),(5,4),(6,4)

Now, for district B: 4 Os and 2 Xs — say (1,5),(2,5),(3,5),(4,5) and (1,1),(2,1)

District C: (5,5),(6,5),(7,5),(8,5) and (3,1),(4,1)

District D: (9,5),(10,5),(1,6),(2,6) and (5,1),(6,1)

District E: (3,6),(4,6),(5,6),(6,6) and (7,1),(8,1)

District F: (7,6),(8,6),(9,6),(10,6) and (9,1),(10,1)

District G: now we need one more 4-O district — but we've used:

Os used: district A:6, B:4, C:4, D:4, E:4, F:4 — total 26 Os? Wait no:

A:6

B:4 (cols5 rows1-4)

C:4 (cols5 rows5-8? I said (5,5) to (8,5) — that's 4)

D: (9,5),(10,5),(1,6),(2,6) — 4 Os

E: (3,6) to (6,6) — 4 Os

F: (7,6) to (10,6) — 4 Os

Total Os: 6+4+4+4+4+4=26 Os

But we need 30, and we have 4 left? Columns: col4 used rows1-6 (6 cells), col5 used rows1-8 (8 cells), col6 used rows1-10 (10 cells)? Let's calculate:

Col4: rows1-6 used in A — 6 cells

Col5: rows1-4 in B, rows5-8 in C — that's 8 cells

Col6: rows1-2 in D, rows3-6 in E, rows7-10 in F — that's 2+4+4=10 cells

Total Os used: 6+8+10=24? But earlier I said 26 — mistake.

District A: 6 Os (col4 r1-6)

B: col5 r1-4 → 4 Os

C: col5 r5-8 → 4 Os — but col5 r5-8 is rows 5,6,7,8 — yes

D: col6 r1-2 and col5 r9-10? I said (9,5),(10,5) for D — but col5 r9-10 not used yet? In C I used r5-8, so r9-10 free.

In D: I said (9,5),(10,5),(1,6),(2,6) — so 4 Os

E: (3,6),(4,6),(5,6),(6,6) — 4 Os

F: (7,6),(8,6),(9,6),(10,6) — 4 Os

Now Os used:

Col4: r1-6: 6

Col5: r1-4 (B), r5-8 (C), r9-10 (D) — that's 10 cells — all of col5

Col6: r1-2 (D), r3-6 (E), r7-10 (F) — 10 cells — all of col6

Plus col4 r1-6: 6

Total Os: 6+10+10=26? But col4 has 10 cells, we used only 6.

Mistake: in district A, I used only 6 of col4, but col4 has 10 cells.

So remaining Os: col4 r7-10: 4 cells.

And we have made 6 districts so far? A,B,C,D,E,F — that's 6 districts.

We need 7 Os-won districts.

So district G: take the remaining 4 Os: col4 r7-10 — that's 4 Os.

But we need 2 Xs for this district.

So add 2 Xs, say from col1 r1-2 — but may be already used.

In previous districts, we used Xs:

For B: (1,1),(2,1)

C: (3,1),(4,1)

D: ? I didn't specify Xs for D — in my earlier plan for D, I said (9,5),(10,5),(1,6),(2,6) for Os, but need 2 Xs — I forgot to assign.

In district D, I need to add 2 Xs — say (5,1),(6,1)

Similarly, E: Os (3,6) to (6,6), add Xs (7,1),(8,1)

F: Os (7,6) to (10,6), add Xs (9,1),(10,1)

Now Xs used:

B: r1-2 c1

C: r3-4 c1

D: r5-6 c1

E: r7-8 c1

F: r9-10 c1

That's all 10 rows of col1 — 10 Xs.

But we need only 2 Xs per district for 6 districts? 6×2=12, but we have only used 10 so far? Districts B through F are 5 districts? Let's list:

District A: 6 Os, 0 Xs — no Xs used

District B: 4 Os, 2 Xs (r1-2 c1)

District C: 4 Os, 2 Xs (r3-4 c1)

District D: 4 Os, 2 Xs (r5-6 c1)

District E: 4 Os, 2 Xs (r7-8 c1)

District F: 4 Os, 2 Xs (r9-10 c1)

That's 6 districts: A,B,C,D,E,F

Os used: A:6, B:4, C:4, D:4, E:4, F:4 = 26 Os

Xs used: B to F: 5 districts × 2 Xs = 10 Xs

Remaining: Os: 30-26=4 (which are col4 r7-10)

Xs: 30-10=20 (cols2 and 3, all 20 cells, since col1 used)

Now district G: take the 4 remaining Os (col4 r7-10) and 2 Xs, say from col2 r1-2

Then we have 3 districts left for Xs.

Remaining cells: all of col2 and col3 except r1-2 col2 used in G? Col2 has 10 cells, we used r1-2 for G, so 8 left in col2, plus all 10 in col3 — total 18 Xs.

Make three districts of 6 Xs each.

For example:

District H: col2 r3-8 (6 cells)

District I: col2 r9-10 and col3 r1-4 (2+4=6)

District J: col3 r5-10 (6 cells)

Perfect.

And Os won districts: A,B,C,D,E,F,G — 7 districts

Xs won: H,I,J — 3 districts

In each district, one party has majority: for Os-won, at least 4 Os; for Xs-won, 6 Xs.

No ties.

And Os win more districts.

So this works.

Therefore, the solution is possible, and Os can win 7 out of 10 districts.

Now, for the final answer — since the problem is to "solve" it, and given the constraints, the key point is that Os can be made to win 7 districts.

Perhaps the expected answer is the number or the fact that it's possible.

But looking back at the problem: "Solve the problem accurately." and "provide the final correct answer".

Given that, and since it's a gerrymandering task, likely the answer is that Os win 7 districts.

To box it.

But let's confirm if we can get 8 — no, as 8×4=32>30.

So maximum is 7.

Thus, the final answer is that the Os can win 7 districts.

Final Answer: 7
