| C353 This material is used for the study of inscribed and concentric figures. The material consists of 9 green metal frames with bottoms and red insets with 1 set of 5 circles decreasing in diameter and 1 set of 4 squares decreasing in length and Anchura . |
| C354 This material is used for geometry, specifically exercises of equivalent, identical and similar figures. The set consists of 9 green metal frames with bottoms, 1 set of insets divided into squares and rectangles and 1 set of insets divided into triangles (this material is also used for small metal inset work, ‘linear geometric design.’). |
| C355 The Metal Triangles material allows the child to make an analytical study of triangles. The set consists of 4 metal frames with bottoms. The insets are equilateral triangles divided into 1, 1/2, 1/3 and 1/4. |
| C356 This set of material represents three cases of the Theorem Of Pythagoras. In the first, 2 sides of the triangle are equal; in the second, the sides of the triangle are in the proportion of 3: 4: 5; and in the third, the general case (the Euclidean demonstration) is shown. The material consists of 3 green metal plates with bottoms and blue, red, yellow and white inset pieces. |
| C357 The Equivalent Figure Material provides experience in studying the relationship of equivalent figures that leads to the discovery of area and theorems. The material consists of 13 green metal frames with bottoms and red insets. |
