The reason why teachers were right all along is because they studied the mandatory college course of Child Development, unlike their business school curriculum developers. The Piaget child development model, the most accepted model of child development for childhood learning, teaches that:

  • Ages 2-7 learn by play, hands on, manipulatives,
  • Ages 7-11 are concrete thinkers which is why addition, subtraction, multiplication formulas and multiplication tables are successful with this group, and finally,
  • 11 and older is when logic develops and is a good time to introduce algorithms, algebraic equations, and different ways to figure out and understand new ways to get an answer.

The baby crawls before walking and walks before jumping because of their muscle development. Babies will not be better athletes if made to jump first. Children will not be better students if made to do algebraic equations in kindergarten
