Math Delight - 1

Universal Active Math

Math has many languages

The language of hands and fingers

The language of words
The language of sounds
The language of pictures
The language of things
The language of shapes
The language of patterns
The language of numbers

Math does not have only one

language. Therefore it cannot
be learned only through paper,
pen or blackboard nor can it be
memorized/ learned by rote.

Universal Active Math method aims at

introducing all the languages of math.
We will use objects for the language
of things, and then for the language
of pictures and the language of
numbers we will use Math Delight.

A child who is familiar with this

way of learning math, would enjoy,
discover, understand, and master math.
