Measurement and Conversions · Learning goals
Convert between feet and inches, meters and centimeters, hours and minutes, and use area and perimeter formulas to solve problems.
Why it matters
Changing feet to inches or hours to minutes is a real skill used in cooking, building, sports and travel.
Using area and perimeter formulas is a first step toward the algebra kids learn in middle school.
Every conversion uses multiplication or division, keeping those facts sharp.

Lesson preview
This is the real lesson text your child hears, read aloud by a friendly voice.
To change big units to small units, multiply. 3 feet = 3 × 12 = 36 inches.
1 meter = 100 centimeters, 1 kilogram = 1,000 grams, 1 hour = 60 minutes.
Area of a rectangle = length × width. Perimeter = 2 × length + 2 × width.
If you know the area and one side, divide to find the other side: 48 ÷ 6 = 8.
For parents
Learning sticks best when kids use it in real life. Here are simple ideas from this course.
Measure a room in feet, then ask your child to convert to inches. Work out the area to see how much carpet you would need.
