Fill in the missing numbers in the multiplication number snake puzzle.

Let’s solve this step by step.

We are given a “Number Snake” where each box is connected to the next with an operation like “×2”, “÷3”, etc. We need to fill in all missing numbers — but looking at the image, it seems most boxes already have blue numbers filled in. The instruction says “Fill in all the missing numbers,” so maybe we’re supposed to verify or complete any blanks? But in the provided image, every box has a number.

Wait — perhaps the student is meant to check if the chain is correct? Or maybe some numbers were originally blank and now filled? Since the image shows an “ANSWER KEY”, likely all answers are already there. But let’s double-check one path to make sure the math works.

Let’s pick a starting point: top left is 1 → ×2 = 2 → ×1 = 2 → ÷2 = 1? Wait no — from 2 (top row) down to 2 (second row): that’s labeled “×1” — which means multiply by 1 → 2 × 1 = 2 ✔️

Then from that 2 → ×5 = 10 ✔️
From 10 → ×4 = 40 ✔️
From 40 → ×2 = 80 ✔️
From 80 → ×3 = 240 ✔️
From 240 → ×2 = 480 ✔️
From 480 → ×1 = 480 ✔️
From 480 → ×2 = 960 ✔️

Now go back up: from 480 (bottom right) ← ×1 from above? Actually, arrow points UP from 480 to 480? That doesn’t make sense unless it’s same value.

Actually, let’s trace another path: start at 1 → ×2 = 2 → then down ×1 = 2 → then left ×½? Wait no — from 2 (second row, second column) ← ×½ from 4? So 4 × ½ = 2 ✔️

Then 4 ↓ ×3 = 12 ✔️
12 → ×2 = 24 ✔️
24 ↓ ×1 = 24 ✔️
24 ← ×½ from 48? 48 × ½ = 24 ✔️
48 ↓ ×2 = 96 ✔️

Another branch: 20 → ×3 = 60 ✔️
60 ↓ ×1 = 60 ✔️
60 → ×2 = 120 ✔️
120 ↑ ×2 = 240 ✔️ (since 120 × 2 = 240)

Also: 10 → ×4 = 40 ✔️
40 → ×2 = 80 ✔️
80 ↓ ×3 = 240 ✔️
240 → ×2 = 480 ✔️
480 ↑ ×1 = 480 ✔️
480 ↓ ×2 = 960 ✔️

Bottom row: 240 ← ×2 from 120? 120 × 2 = 240 ✔️
120 ← ×1 from 120? Same number — okay
120 → ×2 = 240 ✔️
240 → ×4 = 960 ✔️

All operations check out. Every multiplication/division matches the result shown.

So even though the worksheet says “fill in missing numbers,” in this answer key version, everything is already filled correctly.

Therefore, the completed snake is as shown — no changes needed.

Final Answer: All numbers are correctly filled in as shown in the answer key.
