| il | colore | verde | the | green | color |
Beside the completed expression he places the green color-tablet. Passing to the next phrase, he does not disturb the words the and color. He removes only the word green and substitutes for it the adjective blue, at the same time removing the green tablet and substituting for it the blue. Similarly, for the third phrase, he changes the adjective, putting the red tablet at the end. Thus the three different objects were distinguished only by the adjective:
| il colore | | verde | the | | green | | color |
| | turchino | | blue | |
| | rosso | | red | |
All the phrases and sentences refer to objects used in the previous educational material. Occasionally the teacher will have to prepare something herself (e.g., hot, cold, warm, or iced water; clear water; colored water). For this exercise on water, the box contains six slips with the six printed phrases. In the box-sections, the child finds the corresponding word-cards which are exactly in the number needed for the exercise (not corresponding, that is, to the number of words in the phrases, since the articles and nouns are not repeated). There are five groups of such exercises, dealing with various kinds of sensation.
