The Line of 20, 106 pages + plastic tool
This edition of The Line of 20—new, improved and enriched with illustrations—is the alternative to colored rods in primary school maths teaching. The method valorizes the intuitive skills of children who, according to recent research, are all born with an innate capacity for calculus and enter school with a lot of enthusiasm and information on numbers. Unlike colored rods, which require lengthy instructions, The Line of 20 is a fun and easy method that can be used immediately. It allows arithmetic operations within the number twenty and shows that these arithmetic operations are first of all simple actions such as adding and taking away. Students use the tool as an extension of their own hands and as mental calculus in human beings has evolved through the use of hands, no other explanation is required. The volume contains a complete syllabus for 1st class math including calculus and arithmetic problems, all presented according to the analogical approach. The Line of 20 is designed for students with difficulties in mental calculus, but has proven very helpful also with partially sighted or hearing impaired persons, and also with foreign students. It can also be a wonderful aid for parents who want to teach their children maths before their actual entry to school.
