NCERT Class 2 Maths Chapter 5 Playing with Lines: what it teaches

Children learn that lines have directions: standing (vertical), sleeping (horizontal), slanting and curved. Yoga poses, drawing and paper folding make it physical, and it prepares them for writing letters and numbers neatly.

Why it matters later. Knowing line directions helps with handwriting, drawing shapes accurately and, later, angles and symmetry.

tight: straightloose: curved
A thread shows straight and curved in seconds.
Dot paper makes neat standing, sleeping and slanting lines.
red: straight folds, blue: slanting
Folding paper shows lines in many directions.

You need

  • a piece of thread or wool
  • paper to fold
  • crayons
  • dot paper (draw a grid of dots)

Tonight’s 10 minutes

  1. Hold a thread tight between two hands: straight line. Move hands closer: curved line.
  2. Do three yoga poses together and name the lines your body makes.
  3. On dot paper, draw a house using only standing, sleeping and slanting lines.
  4. Fold a paper several times, open it and trace the fold lines in two colours: straight and slanting.

Words to use

  • straight
  • curved
  • standing (vertical)
  • sleeping (horizontal)
  • slanting

Watch for

  • Thinking a slanting line is not straight. Hold the tight thread at an angle. It is still straight, just tilted.
  • Mixing up standing and sleeping lines. Ask “Is it standing up like you, or lying down like you in bed?”

What it sounds like at home

A short example of the conversation. Your words will differ; the questions are what matter.

YouHold the thread tight. Is it straight?

Your childYes.

YouNow tilt it. Still straight?

Your childYes, but slanting.

YouBring your hands together.

Your childNow it’s curved.

A game for this week: Line spotter

  1. Walk round a room together.
  2. Call out a line type: “slanting!”
  3. Your child points to one: a ladder, a roof, a hanger.
  4. Score a point for each correct spot. Swap roles.

A 5-day plan, 10 minutes a day

  1. Day 1Straight and curved with a thread.
  2. Day 2Yoga poses and body lines.
  3. Day 3Dot paper drawing with straight lines.
  4. Day 4Curved-line drawings: clouds, rainbows.
  5. Day 5Line spotter game.

Everyday moments to practise

  • Door edges stand up; the floor lies down.
  • A ladder has slanting lines.
  • A rainbow and a smile are curved.
  • Letters on the TV screen: count straight and curved.

Quick check

Ask these at the end of the week. Tap to see the answer.

Is the edge of a door a standing or sleeping line?

Standing (vertical).

What kind of line is the top of a rainbow?

Curved.

Draw a letter using only straight lines.

For example A, E, F, H, K, L, M, N, T, V, W, X, Y, Z.

Ready for the next chapter when your child…

  • Names standing, sleeping, slanting and curved lines.
  • Draws each type on request.
  • Spots all four types around the house.

Questions parents ask

What lines are taught in Class 2 maths?

Straight lines in three directions (standing/vertical, sleeping/horizontal, slanting) and curved lines.

Is a slanting line straight?

Yes. It is straight but tilted.

How does paper folding help?

Each fold makes a straight crease; different folds make different directions to compare.
