In the sixth grade, a bridge is built between fractions and the decimal system, in the form of decimal fractions and percentages. 5in b1900-part2 Part 2 The Road to Abstraction — Principles of Teaching If you can’t explain a concept to a six-year-old, you don’t fully understand it. 5in b1900-part2 Conveying Abstractions The King’s Road to Abstraction During a sabbatical I spent in North America, I slipped on some ice and injured my shoulder. The doctors deliberated whether to operate or not. I consulted a renowned specialist, who was all for operating.

The same is true of abstractions — you can’t just place them on someone. They need to be established from the bottom up, from their concrete foundations. A piece of information can be conveyed to another person; abstractions must be established alone, and the teacher can only help by guiding to their specific examples. No person, child or adult, can understand an abstraction just from its wording. If one does understand, it is because he already had an available example in his mind. The same is true not only of teaching mathematical ideas, but also of the way they are formed.

We are unaware of most of our basic mechanisms of thought. Everyone knows, for example, that if you climb up 4 steps, you have to climb down 4 steps to get back to the starting point. However, we weren’t born with this knowledge. Acquiring it was a true accomplishment. The following is a list of several structures of thought of which a child starting school has a certain perception. One should remember that the child’s grasp of these principles is usually vague and intuitive, and therefore they have to be taught again, this time explicitly.
