Math
“… Because of this vital importance of mathematics the school must use special methods for teaching it and make clear and comprehensible its elements with the help of plenty of apparatus that demonstrates the materialized abstractions of mathematics …” - Maria Montessori (From Childhood to Adolescence)
When the child is introduced to writing and reading, he is also prepared to understand the figures representing numbers. The child’s mind needs to be fed with concrete and accurate materials, which is why hea is given clear and precise tools that are specifically made for him to help satisfy these needs.
