🔍 Key Concepts
• Metric prefixes and how they scale by powers of 10
• The sequence of common prefixes: kilo, mega, giga, tera
• How many zeros are in a thousand, million, billion, and trillion
💭 Think About
• Start with what you know: if kilo is 10 to the 3rd and mega is 10 to the 6th, what comes next in order?
• Think about digital storage sizes: kilobyte, megabyte, gigabyte, terabyte—how does each step change the size?
• Match each word (thousand, million, billion, trillion) to the number of zeros, then connect that to powers of 10.
✅ Before You Answer
• Be sure you know that kilo = 10^3 and mega = 10^6 before deciding on giga
• Confirm how many zeros are in a billion vs a trillion
• Check that your choice fits the pattern of increasing size: kilo < mega < giga < tera
