Metric Conversion Challenge Warm-Up - ppt video online download - Free Printable

Let's solve this Metric Conversion Challenge Warm-Up step by step, using the "Ladder Method" (also known as the metric prefix ladder). This method helps convert between metric units by moving the decimal point based on the number of steps between prefixes.

🔹 Part 1: Write the correct abbreviation for each metric unit

| Unit | Abbreviation |
|----------------|--------------|
| 1) Kilogram | kg |
| 2) Meter | m |
| 3) Gram | g |
| 4) Milliliter | mL |
| 5) Millimeter | mm |
| 6) Liter | L |
| 7) Kilometer | km |
| 8) Centimeter | cm |
| 9) Milligram | mg |

✔ These are standard metric abbreviations.

🔹 Part 2: Metric Conversions Using the Ladder Method

The metric ladder goes like this (from largest to smallest):

> kilo (k) → hecto (h) → deka (da) → base unit → deci (d) → centi (c) → milli (m)

Each step is a factor of 10, so we move the decimal point one place per step.

We’ll go through each conversion:

---

#### 10) 2000 mg = ______ g
- From milligram (mg) to gram (g): move 3 steps up (mg → g)
- Move decimal 3 places left:
2000 mg = 2.000 g → 2 g

✔ Answer: 2 g

---

#### 11) 104 km = ______ m
- From kilometer (km) to meter (m): move 3 steps down
- Move decimal 3 places right:
104 km = 104,000 m

✔ Answer: 104,000 m

---

#### 12) 480 cm = ______ m

🧠 Tips for the Ladder Method:

- Up the ladder (to larger units): move decimal left
- Down the ladder (to smaller units): move decimal right
- Count the number of steps between prefixes
- Each step = ×10 or ÷10
