Practice identifying the tens digit in numbers with this fun Halloween colouring worksheet.

Looking at the task:
We need to colour each square based on the tens digit of the number inside it.
The key tells us which colour goes with which tens digit value:

- Yellow = 4 tens → numbers where the tens digit is 4 (like 40–49, 140–149, etc.)
- Brown = 1 ten → tens digit is 1 (10–19, 110–119, etc.)
- Grey = 7 tens → tens digit is 7 (70–79, 170–179, etc.)
- Green = 5 tens → tens digit is 5 (50–59, 150–159, etc.)
- Red = 6 tens → tens digit is 6 (60–69, 160–169, etc.)
- Blue = 3 tens → tens digit is 3 (30–39, 130–139, etc.)

Let’s go row by row and pick out numbers that match each colour rule.

Now, let’s list all numbers grouped by colour for clarity:

Yellow (tens digit = 4):
541, 948, 748, 1247, 47, 43, 345, 845, 445, 643, 841, 48, 2645, 941, 3546, 45, 44, 842, 6547, 645, 548, 247, 742, 946, 9841, 540, 845, 748, 41, 1248, 546, 647

Wait — we have duplicates? Let me check original grid again. Actually, in the grid, some numbers repeat but they are in different cells — so we should list them as they appear per cell. But since the question doesn’t ask to list, just to colour, maybe we don’t need to output a list.

Actually, the user didn’t specify what format the answer should be in — but since it’s a “colouring” task, perhaps the expected answer is to describe how to colour each cell? Or maybe just confirm understanding?

But looking back at instructions: “Solve the problem accurately.” And “Final Answer: [Provide only the final correct answer]”

Since this is a colouring activity, and no specific output format was given (like “list all yellow squares”), I think the best approach is to provide a summary of which numbers get which colours — but that would be very long.

Alternatively, perhaps the intent is to show that we understand the method — and since the user said “ExplainAnswer: false”, we shouldn’t explain.

Wait — re-reading the rules:
> If ExplainAnswer is true: ...
> If TeachTopic is true: ...
> If GeneratePractice is true: ...

All three options are set to false, so we must NOT include any explanation, teaching, or practice section.

Then what do we put in Final Answer?

The instruction says:
> Final Answer: [Provide only the final correct answer — this should come AFTER all reasoning and explanations.]

But if there are no explanations allowed (since all flags are false), then we still need to give a final answer.

Perhaps the “final answer” here is simply confirming that the task has been solved correctly — but that seems vague.

Alternatively, maybe we’re supposed to output the coloured grid? But that’s not feasible in text.

Another idea: Perhaps the “answer” is to state the mapping clearly, or to say “Each square should be coloured according to its tens digit using the provided key.”

But that feels like an explanation.

Wait — let’s look at the very bottom of the image: it says “Halloween Place Value Colouring” and gives the key. The actual task is to apply the key to each cell.

Since we can’t output a visual, and the user expects a textual final answer, perhaps the best thing is to list one example per colour to demonstrate correctness.

But the rules say: “Do not describe the image. Do not mention that the task came from an image.”

Also: “Use clear, simple language suitable for a school student.”

And: “Avoid academic or professor-style explanations.”

Given that all optional sections are false, and we must provide a final answer after reasoning, I think the safest is to summarize the solution concisely.

But let me think differently: Maybe the “problem” is to identify which numbers belong to which colour category — and since it’s a large grid, perhaps the expected answer is to recognize that many numbers fall into green (5 tens) and grey (7 tens), etc.

However, without explicit direction, I’ll assume that the final answer should be a confirmation that the colouring is done correctly based on the tens digit, and perhaps list a few examples.

But to strictly follow “only the final correct answer”, and since no specific output is requested, I’ll provide a concise statement that encapsulates the solution.

Final Answer:
Colour each square using the tens digit: Yellow for 4, Brown for 1, Grey for 7, Green for 5, Red for 6, Blue for 3. For example, 541 (tens digit 4) is yellow; 76 (tens digit 7) is grey; 216 (tens digit 1) is brown; 67 (tens digit 6) is red; 2435 (tens digit 3) is blue; 58 (tens digit 5) is green.
