Step-by-step solution for: 3rd Grade Rounding Mystery Pictures Coloring Worksheets
The image you've uploaded is a "Rounding Numbers Mystery Pictures" worksheet designed for students to practice rounding numbers while revealing a hidden picture through coloring. Let's break down how to solve this type of puzzle and explain the solution process step by step.

There are two main parts:
1. Left Side (Problem Sheet):
- A list of numbers to round to the nearest 10 or 100.
- Each rounded number corresponds to a color code.
2. Right Side (Grid/Coloring Sheet):
- A grid with numbered squares.
- Students color each square based on the rounded number and its assigned color.
When completed, the colored squares reveal a mystery picture — in this case, three mushrooms.

#### ✔ Step 1: Understand the Instructions
- Round each given number to the nearest 10 or 100.
- Use the rounded result to find the corresponding color from the key.
- Color the matching squares on the grid.
> Example:
> If the number is 74 → round to 70 → look up what color 70 corresponds to (e.g., Orange).
#### ✔ Step 2: Solve the Rounding Problems
Let’s go through the example problems shown:
| Number | Rounded to Nearest 10 | Color |
|--------|------------------------|-------|
| 37 | 40 | Green |
| 51 | 50 | Yellow |
| 74 | 70 | Orange |
| 86 | 90 | Red |
| 99 | 100 | Purple |
| 147 | 150 | Blue |
| 173 | 170 | Pink |
| 193 | 190 | Brown |
> Note: The exact colors may vary slightly depending on the legend provided, but in this worksheet, the color key is likely listed at the top.
#### ✔ Step 3: Use the Color Key to Fill the Grid
On the right-hand side, there's a large grid labeled “SQUARES” with numbers inside each cell.
- Find the number that matches your rounded answer.
- Color that square using the assigned color.
For instance:
- If 40 → Green, then any square labeled "40" should be colored green.
- Repeat for all numbers.
#### ✔ Step 4: Reveal the Mystery Picture
As you color the correct squares, a pattern emerges.
In this case, the final image is three colorful mushrooms:
- One yellow mushroom (top left)
- One purple mushroom (top right)
- One red mushroom (bottom center)
These are made up of colored squares arranged in a specific pattern.

This activity combines math skills (rounding) with art, making learning fun and engaging.
It reinforces:
- Understanding place value
- Rounding rules (look at the digit to the right; 5 or more rounds up)
- Following directions
- Pattern recognition

👉 The mystery picture is three mushrooms — a fun reward for completing the math tasks!
---
- Double-check rounding (e.g., 95 → 100, not 90).
- Use a pencil first if unsure.
- Keep track of which numbers you’ve already colored.
---
✔ Answer: The mystery picture revealed after solving and coloring is three mushrooms — one yellow, one purple, and one red — created by rounding numbers and coloring the correct squares.
