What are The Constructive Blue Triangles?

The Constructive Blue Triangles are all painted blue, and identical in size.  As an extension to the traditional Montessori activity; the 5 boxes of Constructive Triangles; this activity will challenge children. 

Using all their previous experience; gained through their prior work; the Child now attempts to make as many different geometric shapes from these 12 identical right-angled scalene triangles.  The constructive blue triangle activity set has a number of exercises that allows the Child to work independently, and self-check their answers.

Objectives of The Constructive Blue Triangles

• the direct objective is to
  • further develop the Child’s experience of right-angled scalene triangles
  • to make as many different triangles and quadrilaterals, as possible, by manipulating the triangles
• indirectly, the Child;
  • learns about geometry
  • improves their ability to understand shape, area, and solve problems
  • learns how many things in life are made up of triangles
  • places triangles together, and learns to make an independent third shape
  • improves their creative skills
• this activity is standard support material for all geometric curricula

Features – The beautifully made shapes, are matte blue, and very smooth to the touch
