Metric Units Length Km M Cm Mm Decimals Practice Activities
Class 4 students convert between kilometres, metres, centimetres, and millimetres using decimal notation through real-world measurement tasks.
Practice that builds confidence
The ×10 Ladder
Children practise converting metric length units—kilometres to metres, metres to centimetres and millimetres—while working with decimal numbers up to three places. Activities progress from place-value charts to multi-step word problems set in Indian contexts like road distances and tailor measurements.
The printable set includes conversion tables, number-line jumps, ruler-reading tasks, and mixed-practice cards. Each page reinforces the ×10 / ÷10 pattern that links every adjacent unit.
Students revisit the metric staircase: 1 km = 1 000 m, 1 m = 100 cm, 1 cm = 10 mm. Worksheets open with a partially completed ladder; learners fill missing arrows (×10, ÷10, ×100, ÷100) and explain the pattern in one sentence.
Decimal Notation Focus
Class 4 expects fluency with decimals. Tasks present lengths like 2.375 km and ask for metres (2 375 m) and centimetres (237 500 cm). Place-value grids keep digits aligned, preventing the common error of misplacing the decimal when multiplying by 1 000.
Ruler & Tape Measure Reading
Photographs of a 30 cm ruler and a 1.5 m tailor’s tape show readings such as 4.7 cm and 1.23 m. Students record each in all four units, noticing that 4.7 cm = 47 mm while 1.23 m = 123 cm = 1 230 mm.
Real-World Word Problems
Contexts include: "Delhi to Jaipur is 281.5 km. Express in metres." and "A kurta needs 2.25 m cloth. How many centimetres?" Multi-step problems combine addition and conversion: "Rohan walks 1.2 km, then 850 m. Total distance in kilometres?"
Parent Routine & Teacher Tips
At home, measure family heights in cm, then convert together to m and mm. In class, set up a "Conversion Relay": teams race to rewrite five lengths on the board in all four units, passing the marker like a baton.
Common Errors to Watch
• Shifting the decimal the wrong direction (×100 instead of ÷100) • Dropping trailing zeros (writing 2.5 m as 25 cm instead of 250 cm) • Confusing 1 km = 100 m (missing a zero)
Kid-Friendly Strategy
"King Henry Died Drinking Chocolate Milk" (kilo, hecto, deca, deci, centi, milli) works, but for Class 4 simply chant: "Big to small—multiply. Small to big—divide."

Why iBloom Worksheets Help
The decimal-first approach matches the NCERT emphasis on decimal notation for metric conversion. Visual ladders and place-value grids make the ×10 structure explicit, not memorised.
Helpful answers
