Powers of 10 and Place Value · Learning goals
See how digits move when you multiply or divide by powers of 10, use exponents like 10^3, and round decimals.
Why it matters
Understanding how digits shift makes multiplying and dividing decimals much easier and less error-prone.
Writing 1,000 as 10³ is a first look at exponents, which kids use a lot in middle school math and science.
Converting units like meters to millimeters uses powers of 10 all the time.

Lesson preview
This is the real lesson text your child hears, read aloud by a friendly voice.
Multiply by 10 and every digit moves one place to the left: 3.45 × 10 = 34.5.
Divide by 10 and every digit moves one place to the right: 72 ÷ 10 = 7.2.
An exponent tells how many tens to multiply: 10^3 = 10 × 10 × 10 = 1,000.
Round 4.68 to the nearest tenth: look at the hundredths digit. 8 is 5 or more, so it's 4.7.
For parents
Learning sticks best when kids use it in real life. Here are simple ideas from this course.
Ask how many cents are in 10, 100 and 1,000 dollars, then how many dollars 1,000 cents makes. Talk about how the digits move.
