Una estrategia de cálculo mental con
Softa [21]

Esta estrategia se puede aplicar sumando  15,75 + 0,25, –1,8 + –0,20, 3,5 + 12,5 y 2,62 + 7,38 antes de sumar el tercer número dado en cada caso.

<h3>¿En qué consiste está estrategia?</h3>

La estrategia propuesta consiste en sumar dos números decimales que den como resultado un número entero antes de sumar el tercer número decima. Por ejemplo si teneos  1,4 + 0,6  + 1,2, se debe sumar primero 1,4 + 0,6 lo que es igual a 2 antes de sumar el 1,2.

<h3>¿Por qué utilizar esta estrategia?</h3>

Este estrategia es beneficiosa porque facilita sumar números decimales.

<h3>¿Cómo aplicar está estrategia?</h3>
  • 15,75 + 1,2 + 0,25 = 16 (0,25+15,75) + 1,2 = 17,2
  • (–1,8) + 2,45 + (–0,20) = -2 (-1,8-0,20) + 2,45 = 0,45
  • 3,5 + 11,8 + 12,5 = 16 (12,5+3,5) +11,8 = 27.8
  • 7,38 – 1,5 + 2,62 = 10 (7,38+2,62) + 2,62 = 12,62
