Drawing and Constructing 2D Shapes

Students will use rulers and other tools to draw and construct various 2D shapes.

Key Questions

  1. Design a method to draw a perfect square using only a ruler and pencil.
  2. Critique the accuracy of a drawn shape based on its properties.
  3. Explain the steps involved in constructing a hexagon.

About This Topic

The Human Figure in Motion takes students from drawing 'stick men' to understanding the 3D mechanics of the human body. In 3rd Class, students use wire, pipe cleaners, or cardboard armatures to create figures that can run, jump, or dance. This topic focuses on the NCCA Construction and Drawing strands, emphasizing 'Visual Awareness' of proportion and the way joints allow for movement. By building a 'skeleton' first, students learn how the body is structured before they add 'flesh' or clothing.

This topic is highly kinesthetic. It encourages students to use their own bodies as a reference point. Students grasp this concept faster through role play and peer observation, where they freeze in an 'action pose' for their partner to study and replicate in wire.

Active Learning Ideas

Watch Out for These Misconceptions

Common MisconceptionArms and legs come out of the head or the very bottom of the body.

What to Teach Instead

Students often struggle with where limbs attach. Hands-on modeling with 'jointed' cardboard puppets helps them see that arms attach at the shoulders and legs at the hips.

Common MisconceptionLimbs are straight lines that don't bend in the middle.

What to Teach Instead

Many 3rd Class drawings lack elbows and knees. Role-playing 'robot' vs. 'human' movement helps them identify exactly where the body hinges.

Frequently Asked Questions

What is the best wire to use for 3rd Class?
Aluminum craft wire is ideal because it is very soft and easy to bend with small hands, yet it holds its shape well. Pipe cleaners are a great, cheaper alternative for initial practice and 'sketching' in 3D.
How can active learning help students understand the human figure?
The human body is the most familiar yet complex subject. Active learning strategies like 'The Human Mannequin' allow students to feel the pose in their own muscles before trying to build it. This physical 'muscle memory' helps them understand angles and proportions in a way that looking at a 2D diagram simply cannot match.
How do I help students make their sculptures stable?
Teach them to create a 'base', either by looping the wire into a large circle at the feet or by sticking the wire into a small block of clay or a piece of heavy cardboard.
Does this topic link to PE?
Yes, it's a perfect link to the 'Gymnastics' or 'Athletics' strands. Students can analyze the 'shape' of their bodies during different movements and then translate those shapes into their art.
