Teaching kit “Exploring the material world” Discovering forms

Triangle, square, circle and other forms… By widening the range of observation and encouraging comparison, the teacher helps the children to distinguish various types of criteria (form, size, mass, capacity etc) and to establish classifications and

Activity 20 : Triangle, square, circle and other forms… n This activity requires supervision. n Children can repeat the experiments on their own after working on them with the mediator.

NB ! Although the names of some shapes are introduced (square, triangle, rectangle, circle), the main aim is not to learn mathematical vocabulary.

At the end of a period of supervised activity, the child should be able to… 1. differentiate and classify objects according to characteristics related to their shape; 2. recognise, classify and name simple forms : square, triangle, circle; 3. reproduce an assembly of simple forms on the basis of a model (puzzle, tiling, assembly of solids).
