Metric Prefix Wheel | Unit Conversion Tool | Science & Math Classroom Manipulative | STEM Teacher Resource | Decimal Mover

Mastering the metric system just got easier! The Prefix Wheel is a hands-on, visual tool designed to help students understand and perform unit conversions with confidence. No more guessing whether to multiply or divide—this wheel shows you exactly what to do.

How It Works:

Set Start: Rotate the center wheel so the "Start" tab aligns with your original prefix (e.g., Kilo).

Set End: Rotate the top wheel so the "End" tab aligns with your desired target prefix (e.g., Centi).

Get the Answer: Look at the window below the "End" tab. It instantly displays the math operation needed to convert your value (e.g., "x 100,000").

Educational Benefits:

Visualizes Decimal Movement: The wheel's layout physically demonstrates the relationship between prefixes. Moving from "Start" to "End" on the wheel corresponds to moving the decimal point left or right in your number.

Covers Core Units: Perfect for converting Meters (length), Liters (volume), and Grams (mass).

Range: Covers standard prefixes from Kilo- (1000) down to milli- (0.001).

Product Details:
