ALGEBRA OUR WAY TODAY:http://bookstore.xlibris.com/Products/SKU-0112143017/Baby-Algebra-For-Baby-and-You.aspxIntroducing baby to algebra as early as the baby shower via algebra themed baby beginnings, such as:mobiles, room plaques, pacifiers and other baby algebra paraphernalia,we inundate baby with the message that algebra is important to baby and family tradition.Baby algebra uses pictures and key words to help Baby to generalize and grasp algebra concepts. Therefore we can think our way through the stepping stones called tests. Colors and images react . Colors with one side of the brain, images with the other side of the brain, together create and complete the learning process inherent at birth . WALLA! Baby does algebra.
