An Unspecified Model – Triangles A
-
-
Activity in the kindergarten is recommended for groups of 4-6 children
-
-
For preschoolers, the accuracy of the fold should not be considered
-
The more the child folds, the better the accuracy of the fold. The inaccuracy will not affect the final product.
-
-
Each pupil will receive 2 sheets of origami paper
.
-
-
Folding instructions:
Fold opposite vertices on each sheet.
-
It is recommended to ask the children to place a vertex on the opposite vertex and then make the fold using the term ‘use a finger to make the fold’
-
-
A kindergarten teacher demonstrates only her paper. If necessary, repeat the demo several times. Never touch the child’s folded paper.
-
Acquiring confidence in folding is a process that cannot be interfered with.
-
-
Working in pairs: The children will connect the triangles to create a figure from their imagination
-
-
Children should be encouraged to verbally describe the figure they have created

-
Question: We ask the children to count the number of vertices and the number of sides of the triangle
-
-
Answer: The children will choose three vertices and three sides and give the name a shape, a triangle
-
From here on, the correct terms should be used to describe the elements of the triangle (vertex, side, triangle)
-
-
Composition and decomposition: We ask each child to place the triangles together so that the triangle’s side is fully attached to the side of the second triangle, and a larger triangle will be obtained.
-
Composition and decomposition:The children will place the triangles together so that the triangle’s side is fully attached to the side of the second triangle. It is best to demonstrate to the children what is meant by pinning ribs.
It is recommended to ask the children to count the sides and vertices of the triangle they formed.
-
-
Folding instruction: Fold one of the triangles vertically in half, so that one vertex lies on top of the other. Unfold
-
It is advisable not to check the accuracy of the folds and not to mention the word precision.
Even if the children folded inaccurately, the final result will come out well.
-
-
Folding instruction: We will fold each of the vertices to the line of symmetry
-
The child still does not know the term ‘line of symmetry’, so it is necessary to show the line of reference with a finger
During folding, it is recommended not to touch the child’s work and not to correct or re-arrange it
-
-
Folding instruction: Fold the vertices as shown in the animation
-
יDemonstrate with your paper so that children will understand which of the vertices to fold.
-
-
Folding instruction: Open the big triangle a bit
-
It is recommended to allow the children to create a design with their own markers
-
-
Model presentation: We ask each child to draw and design the final result.
-
It is recommended that the decoration be done only with markers (and not with stickers).
The teacher will not design her model before the children have designed their own.
-
-
Presentation of the model: We ask each child to describe the final model that was created from his/hers imagination and choice.
-
It is important that the children verbally describe what they have designed
-

-
- Lesson Aims
The child could distinguish between different polygons according to the number of sides or vertices
The child forms the shape
Development of the ability to verbally and visually describe the representation of spatial relations (decomposition and composition)
- Name of Model
The child decides what the final result is
- Prior knowledge
Not required
- The curriculum
- Materials
