The Cuisenaire Gattegno Method Of Teaching Mathematics

1 + 3 + 5 = 32 1 + 3 + 5 + 7 = 42 and so on, by means of a pyramid of rods adapted to enable the relationship to be seen. 4 It is similarly discovered that 2+4=3×2 2+4+6=4×3 2+4+6+8=5×4 and so on. 5 Finally, using these discoveries about the sum of the first odd numbers and the sum of the first even numbers, the pupils are guided into combining the two ideas, enabling the sum of the first whole numbers to be rapidly found: 1 + 2 = 12 + (2 × 1) 1 + 2 + 3 = 2 + (2 × 1) 1 + 2 + 3 + 4 = 22 + (3 × 2) and so on up to the first 20 whole numbers.
