Rounding Rocket: Orbital Launch
Precision Engineering
T-Minus 10 Seconds! To reach orbit, your calculations must be precise—but not too precise. In Rounding Rocket, you fuel the engines by rounding large numbers to the nearest 10, 100, 1,000, 10,000, or 100,000.
Rounding is a critical skill for estimation and checking answers. This game visualizes the concept: get close enough to the target, and you achieve lift-off.
🚀 Flight Manual (The Rules)
- High 5 Rule: "5 or more, let it soar (round up). 4 or less, let it rest (round down)."
- Degree of Accuracy: Rounding to the nearest 10 is different from rounding to the nearest 1,000.
- Place Value: Identifying which digit determines the rounding (e.g., for nearest 100, look at the tens digit).
Mission Control (Year 6)
Rounding
Round any whole number to a required degree of accuracy (up to 10,000,000).
Place Value
Read, write, order and compare numbers up to 10,000,000 and determine the value of each
digit.
👨👩👧 Flight Director's Tip
Visualizing the number line:
- "Imagine a hill. Multiples of 10 are at the bottom. 5 is at the top. If you're at 5, you roll forward to the next 10."
- "Underline the digit you are rounding to. Circle the digit to its right. The circled digit is the 'Boss'. It tells you what to do."
