Linear Measurement: Ropes, Jumps and Boundaries - Class 4 Maths Worksheet
Read a ruler from any mark, use metres and centimetres, half and quarter metres, and find the perimeter of pitch plans and shapes on a dot grid.
Learning Objective
Read a ruler (also from a mark other than 0), know 1 m = 100 cm, change between metres and centimetres, use half and quarter metres, estimate lengths and find the perimeter of simple shapes.
Skills Practised

Interactive Story Mission
Join Coach and Pariskhit for a 10-minute football training story. Children work through 12 activities with big buttons, kind feedback, hints when they get stuck, and a badge and stars at the end.
- Read the Ruler: Read where the lace ends.
- Not Starting at Zero: Find where it starts and where it ends.
- A Broken Ruler: Drag the length into the goal.
- Tenth of a Rope: Look at the 1 m rope cut into equal parts.
- A Half Rope: Look at the 1 m rope cut into 2 equal parts.
- Marks on a Tape: Tap the missing mark.
- Shorter or Longer Than 1 m: Tap a card. Then tap its group.
- Metres to Centimetres: Read the sign.
- The Longest Boundary: Each side of a square on the grid is 1 cm. Tap the shape with the longest boundary (perimeter).
- Round the L: Count the sides all the way round.
- Stickers on a Board: Drag the number into the goal.
- Rope Round the Garden: Add all the sides.
Note for Parents & Teachers
This follows the NCERT Class 4 chapter "Measuring Length". 1 metre is 100 centimetres, so half a metre is 50 cm and a quarter metre is 25 cm. The perimeter is the length of the boundary of a shape. Football fact used: a football goal is 7 m 32 cm wide (as of the date on this worksheet). At home, measure a few things with a ruler and tape and walk round a room to find its perimeter.
