Johann Heinrich Pestalozzi
Johann Heinrich Pestalozzi advocated ‘hands-on-learning’. He asserted that students need to learn through their senses and through physical activity. He proposed ideas such an integrated curriculum, the development of the whole child and "Hand, Head, Heart"
1800 - 1900
The late 1800s saw the invention of the first true manipulative-maneuverable objects that appeal to several different senses and are specifically designed for teaching mathematical concepts.
In 1837, the German educator Friedrich Froebel introduced the world’s first kindergarten. He designed called educational toys as Froebel Gifts or Frobelgaben, which included geometric building blocks and pattern activity blocks.
Jean Piaget specified stages of cognitive development in children, stressing the importance of “concrete operations” in the primary stages of knowledge formation.
In the early 1900s, Italian educator Maria Montessori continued with the idea that manipulatives are important to education. She founded a network of schools based on the education of the senses. She expanded the use of these tools with the belief that their use would enable children to learn through personal investigation and exploration.
