Erickson The Line of 100

The Line of 100, 112 pages + plastic tool A new approach to teaching math in second grade, The Line of 100 follows The Line of 20 utilized in first grade. Relying on natural cognitive skills, The Line of 100 can also be used with children who have never been exposed to the analogical method.

The method is based on an “analogical calculaor” built as a 10-shelf wardrobe. Moving the bars sideways, the student can make additions and subtractions, and immediately understand what it means to divide and multiply. This workbook contains a full set of mental and written calculus exercises and problems. Special attention is devoted to operational learning such as the multiplication table.

All the exercises in the workbook are intuitive and immediately understandable without the help of any prior instructions.

Recommended to all young students with linguistic difficulties, The Line of 100 makes learning math fun and interesting.
