Chapter 5: Playing with Lines

Introduction

Playing with Lines shows children that lines are everywhere — even in our bodies when we do yoga! The chapter starts with pictures of aasanas and asks children to find standing, sleeping, slanting and curved lines in them. It then uses a thread, dot grids, drawing and paper folding to explore different kinds of lines.

What's in this Chapter

  • Lines in aasanas: children circle aasanas with standing (vertical) lines, tick those with both vertical and slanting lines, cross those with curved lines, and put a star on those with sleeping (horizontal) lines. They also try some aasanas themselves. The teacher is asked to tell children about Ashtanga Yoga, described in the ancient Yoga Sutras of Patanjali.
  • What is Straight? Hold a thread tight between your hands — it makes a straight line. Bring your hands closer and it becomes a curved line. A tight thread can be held as a sleeping/horizontal, standing/vertical or slanting line — all of these are straight lines.
  • Trace the missing lines: children trace vertical, horizontal, slanting and curved lines in a picture.
  • Let us Play with Dots: join dots to make new shapes with straight lines, and draw clouds and a rainbow with curved lines.
  • Let us Do: make designs using any two types of lines, then three types, then all types.
  • Project Work — Fun with Folding: fold a paper again and again and look at the creases. Trace straight lines with a red crayon and slanting lines with a blue crayon, see who gets the most creases, and try to make curved lines by folding.
  • The teacher's note suggests discussing art forms like Madhubani, Kalamkari and Warli, and inviting local painters to show how they draw lines and shapes.

    • Key Ideas

  • A straight line does not bend; a curved line bends.
  • Straight lines can be standing (vertical), sleeping (horizontal) or slanting.
  • Lines can be joined to make shapes and designs.
  • Folding paper makes straight creases.
  • Lines are all around us — in our bodies, in art and in buildings.

    • Activities from the Book

  • Doing aasanas and finding lines in body positions.
  • Using a thread to make straight and curved lines.
  • Dot-joining to make shapes.
  • Paper folding to make creases.

    • Words to Learn

  • Line (रेखा)
  • Straight (सीधी)
  • Curved (घुमावदार)
  • Standing / Vertical (खड़ी रेखा)
  • Sleeping / Horizontal (पड़ी / लेटी रेखा)
  • Slanting (तिरछी रेखा)
  • Crease (सिलवट / मोड़ का निशान)
  • Aasana (आसन)
  • Design (नमूना / डिज़ाइन)

    • Tips for Parents & Teachers

  • Do a few simple aasanas together and ask, "Is your back straight or curved now?"
  • Give the child a piece of string to make straight and curved lines on the floor.
  • Look for lines in the home: door edges (standing), shelves (sleeping), a slide or ramp (slanting), a bangle (curved).
  • Show children a Warli or Madhubani painting and let them copy a few lines.

    • Common Mistakes

  • Thinking only vertical lines are "straight" — horizontal and slanting lines are straight too.
  • Calling a wavy line straight because it goes from one side to the other.
  • Mixing up the words "vertical" (standing) and "horizontal" (sleeping).

    • 💡 Key Learning Points

    • ✓Identify straight and curved lines.
    • ✓Name straight lines as standing (vertical), sleeping (horizontal) or slanting.
    • ✓Find lines in body positions (aasanas), pictures and objects around us.
    • ✓Draw shapes and designs by joining dots and combining different lines.
    • ✓Make straight creases by folding paper.

    👨‍🏫 Teaching Tips

    • →Help children practise simple yoga poses, giving instructions like keep the back straight, curve the back, slant the arms.
    • →Tell children about Ashtanga Yoga described in the Yoga Sutras of Patanjali.
    • →Let children hold a thread tight and loose to see straight and curved lines.
    • →Give dot grids and ask children to make shapes using only straight lines.
    • →Use the folding project and ask who gets the most creases.
    • →Discuss Madhubani, Kalamkari and Warli art and, if possible, invite a local painter.
    • →Ask children to make designs using two, three and then all types of lines.

    📋 Assessment Questions

    1. Can the child sort lines into straight and curved?
    2. Can the child show a standing, sleeping and slanting line with their arm or a pencil?
    3. Can the child find vertical and horizontal lines in a yoga pose picture?
    4. Can the child draw a design with at least three types of lines?
