Practicing Multiplication & Division by 10, 100, 1000

Unit conversion is an excellent way to practice multiplication and division by round numbers.

Practical Life Knowledge

Reading maps, cooking, and measuring time all require mastery of these conversions.

Tips for successful practice with children

💡 Show your child a ruler: within 1 centimeter there are 10 small lines (millimeters).

💡 Remember the prefixes: 'kilo' in Greek means thousand (km, kg).

💡 In time, the multipliers are different: 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day.
