=== Age  ===

3-6 <br>

=== Materials  ===

*Constructive Triangle Box<br>

=== Preparation  ===

This is an individual exercise, which is done on a floor mat on the floor. (Note: work cycle to be observed). <br>

=== Presentation  ===

#The Directress shows the child how to take any one of the box individually to the floor mat. 
#She sits beside the child and places the box of shapes in front of the child. 
#Directress shows how to lay out all the contents on the mat. 
#Box 1 -Trace the lines on the shapes with fingers.
#Join up the triangles along the line. 
#Then, use the gray triangle as control of error by holding it just above all the shapes made earlier, (not touching) in turn. 
#The Directress then invites the child to put the shapes together, matching the black lines. the resulting shapes are discussed and named. 
#Directress may use the '''Three Period lesson''' to teach the child the name of the shapes that could be formed with the various shapes, for e.g. hexagon, triangle, rhombus,...etc.

=== Control Of Error  ===

In boxes 1 to 4 there are black lines on the edges of the triangles to be joined to make different shapes, thus providing guidelines and control for the child.<br>The shapes of the boxes (triangular, hexagonal and rectangular) also act as a control of error. <br>

=== Points Of Interest  ===

This is a sensorial exercise and is purely for the child to experience, discover and observe how different geometric shapes can be divided and combined. <br>

=== Purpose  ===

*Provide the child the opportunity to experiment with the various geometric shapes and discover, at a sensorial level, the various ways these shapes can be divided and combined to form other shapes. 
*Indirectly prepare the child for later study of geometry by giving the child visual and muscular experience of shapes. 
*Develop the child's vocabulary.

<br>

=== Variation  ===

The child may select any one of the five boxes, construct shapes and discover properties. <br>

=== Handouts/Attachments  ===
