Materials
- Metal insets of the square and its subdivisions
Preparation
Presentation
- Invite the child to bring out the material and arrange it properly.
- Take any two inset pieces from the same frame.
- Note: Montessori suggests the fourths to be taken from the frame as pictured.
- Superimpose the two pieces.
- Indicating the surface, tell the child that every point of one figure corresponds to a point on the other figure, that is, they can be superimposed perfectly.
- The Norwegians say that one "answers" the other, rather than on "corresponds" to the other.
- This is a special quality that these two figures have.
- We can say that one is congruent to the other.
- Repeat the experience with the other fractional divisions.
