GEOMETRICAL FORM
The pupil is required to study form. There are certain forms to which certain names are applied. They occur frequently in the simplest subjects. Therefore, while these forms are known under the formidable title of geometrical figures, nevertheless most of these shapes are so simple as to be easily recognized and with a little exercise of the memory can be called by name. The easiest way for the child to form their acquaintance is to make and draw them. Their application will readily follow.
Let the teacher cut from cardboard the following geometrical forms:
The Square.
The Rectangle.
The Triangles (right, acute, obtuse and equilateral triangles).
The Circle.
The Oval.
Explain Simple Pictures. Try to explain matters connected with the study of lines and form by means of simple illustrations. For instance, a child may not understand the meaning of parallel lines. Draw for him a little picture of a ladder, showing that no matter how far extended the lines would never meet. Then draw a picture of a half-closed umbrella, and explain the meaning of converging and diverging lines, as shown in Fig. I. Tell him that the lines I, 2 and 3 are converging lines, as they approach toward the ferrule of the umbrella that converging lines tend to get close together.
